Verified Patient Reviews
Extremely rude and rushed. Walked out of the room as I was asking questions.
Very professional and thorough.
very informative and gave specific and detailed review of everything
Very professional and thorough. I didn't feel rushed and she definitely takes the time to be as helpful as possible
Very informative and answered all my questions. Highly recommended!
I was turned off because the practice required you to leave a credit/debit card number in case your insurance didn't pay the SUGGESTED COST for services rendered. The practice will charge your card for the remaining portion of the physician's SUGGESTED COST (which is absurd to me). I waited to see the dr. for a little over 20 minutes, to have a six minute session that ended with the dr. recommending a retinoid cream.
Love this office- clean - new- professional
Check-in was efficient. All of my concerns were addressed and the staff explained what they were looking for throughout the exam. Everyone I met was very friendly and professional.
she's very sweet and patient. I had wonderdul experience with DR. Lian Mark
The receptionist was weird - nobody greeted me when I walked in so I didn't know whether to wait to check in or sit until they called me. They were also confusing about signing the forms and scheduling a follow up.
Dr. Mack was great. I was seen right on time, and the visit lasted about 30 minutes for an annual skin check. She was professional the entire time, talking to me about what she was doing and seeing without me having to ask. All in all a very comfortable and successful visit.
Great appointment. She was confident and knew what to offer me and prescribe in terms of topical medicines. Overall great experience. Thank you.
Love this office. Friendly, thorough, quick and clean!
Dr. Mack is thorough and professional. She made sure to follow up with my prior doctor and make a thoughtful plan before my second appointment. Her office is well run and everyone I encountered was kind and helpful.
Staff was very friendly; answred all my questions.
It was a great experience. I will definitely be back.
A very patient focused office. Top scores all around.
Dr. Lian was very thorough and sweet. I went in for my annual skin screening and she went over all the different types of moles she found and which should be monitored and which are normal, etc. Very bright personality. It was a pleasure being there.
Dr. Mack was super sweet. She explained everything as the exam progressed and answered all my questions. She gave recommendations along with options that would be most beneficial for me
She is very nice and very professional.
Having your naked body scanned is unpleasant, but Dr. Mack makes it as comfortable as possible.
Always super quick but not at all rushed, great location, beautiful office, no upselling of products or procedures. Really a pleasure to see Dr. Mack!
She was fabulous and super warm and welcoming. The office is beautiful
She's awesome - talks you through the whole process and gives recommendations without pushing.
Dr. Mack was sufficient, though I was not overly "impressed." My only complain was that she did seem a bit bored/dismissive of my concerns, so I didn't feel 100% open in sharing my worries.
Doctor Lian was very nice and all the assistants too, They treated the problem with accuracy and making me feel very comfortable.
So kind and honest. Great at listening and addressing your problems head on!
She was very sweet but very straightforward. I felt like she really knew what she was talking about and I had full confidence that she would steer me in the right direction to help my skin.
Dr. Mack was very thorough and thoughtful! She checked over every body part and made detailed documentation of moles/spots to monitor over time. She took the concerns I had addressed with her seriously and was able to give me practical advice on treatments solutions. Highly recommended!
I had a wonderful appointment with Lian and she made me feel very comfortable the entire time. I definitely recommend her to anyone who is in need of a dermatologist.
Dr. Mack was very through and explained my issue along with her recommended treatment plan. Her staff was lovely from the secretary to the PA who helped me onsite. I can't wait for my follow up already!
Very thorough. Explained all the medical terms and processes clearly. Answered all my questions comprehensively. Seemed current in her knowledge. Personable but professional! I have a follow up in 3 weeks. :)
Clean, bright office with kind and competent staff.
The doctor was super knowledgeable. She was friendly, yet professional, and spent the time necessary to answer my questions.
Dr. Mack listens to all my concerns and caught something my previous dermatologist didn't. She takes the time to hear out your history to make the right diagnosis. Friendly staff, clean environment, and knowledgeable doctor!
Dr. Mack is the best!
Super Nice and quick! My issue was only eczema so a bit standard. Totally dedicated to hearing out my issues. Good treatment recommendations and nice office. Go here!
Dr. Mack is great. She is thorough but efficient, so you feel like you haven't been there forever but still like she went through everything carefully.
Dr. Mack really took the time to listen to me and explained my options in depth. She gave me time to ask questions. I was in and out quickly for a cortisone injection but all in all Dr. Mack and her team were very pleasant and thorough.
Very clean and smart decor. Friendly staff.
Quick and easy appointment! Dr. Mack was very knowledgable.
Dr. Mack was very thorough and took the time to listen to all of my symptoms. Would definitely recommend to others.
Dr. Mack was extremely kind and professional. The office was incredible clean and well designed. It feels like your'e stepping into a nice boutique, and not a doctor's office. I look forward to my next appointment with her. Also for a dermatologist, she is a walking billboard. Her skin is incredible, so I very much trust her treatment and advice.
Dr. Mack is amazing! She was prompt, thorough and very knowledgeable. I most definitely will be using her for any dermatological needs in the future
My first visit went so well. The office was very nice and clean; they even had snacks and water for you in the lobby. I didn't wait long before Dr. Mack greeted me. Dr. Mack was personable and knowledgeable. I trusted the suggestions she gave me and felt very positive as I left the office. It was great to speak to someone of color about my skin, I felt like I was in good hands. Can't wait for my second visit!
Overall, she was very pleasant, knowledgeable and approachable. She explained concepts very well. I would highly recommend her. I did have to wait for some time before I was seen, but she appropriately acknowledged the wait time, so I would factor that out for the value of her treatment.
Dr. Mack was extremely friendly, calming, and intelligent. She quickly assessed my skin and provided me with her recommendations, making sure to explain everything in laymen's terms. I am curious to see the results of her recommended prescriptions. Overall great experience!
Dr. Mack and her team are great -- about two weeks before my original appointment, her admin called me to inform me that she would be out of the office and her PA would be seeing me, and wanted to give me the opportunity to reschedule. Because it was my first cosmetic dermatology appointment, I appreciated the option and rescheduled on the phone with no hassle. Dr. Mack is always attentive, personable, and informative -- I appreciate the added knowledge and I have total faith in her expertise!
Lied about copay costs and then charged my credit card multiple times with out my permission! They only want your money, no interest in helping or healing you!
I have horrible skin ulcers/cysts and I’ve been going here for a year regarding this skin condition to no avail or no testing or suggestions on how to improve. The audacity that this could be self-inflicted was my last straw as these lesions are very severe and painful and caused by something that I am paying for her expertise to solve which she apparently doesn't have. I even had to ask Dr. Mack to test for what I thought it could be, and hasn't tried to rule out what it could or couldn't be.
She's great I always feel comfortable with her explanations and recommendations.
The office is very clean, chic and comfortable. Lian Mack was also polite, conversational and treated me super quick. Excellent experience.
legit and welcoming!
I am confident with Dr. Mack and trust her knowledge/skills in her field. Appreciate her calm, careful demeanor. Entire office staff is very friendly and helpful.
Dr Mack is a professional MD. A great experience
Excellent visit. Dr. Mack made me feel comfortable during my visit and gave me some good advice moving forward. I was in and out of the office but didn't feel rushed. Efficient! When I had additional questions right after the appointment she was easy to reach.
She's an expert in her field. I had a very severe outburst in dry skin on my face. She took the time to thoroughly exam my skin and asked about the products I use. She informed me that the expensive face cleanser and moisturizer was actually drying my skin and prescribed a new set of over the counter products that work better with my skin during the winter. Turns out the cleanser I was using should only be used on warm climates. She was extremely professional, warm and inviting. Not to mention that her office is gorgeous and her staff is delightful. I've already recommended her to two friends who equally love her!
GREAT visit with Dr. Mack! It had been a while since I had a full-body check, and Dr. Mack was friendly, open, and explained any terminology she used or issues she was looking for. Fantastic experience and very quick visit. I will definitely be back!
I really enjoyed my visit with Dr. Mack. She was friendly and knowledgable. I liked how she gave me a printout of everything that we discussed during the visit, so I would know the names of everything. Would definitely recommend Dr. Mack and will be coming back for future visits!
She was very friendly and knowledgeable
She was great - explained what every medical term she mentioned meant and was extremely nice.
I think Lian and her staff are well informed and crave being efficient. I loved the comfort they provided and will referred them to everyone I know
Dr. Mack and her staff were great! The office was clean, updated, and cozy. Everyone was very friendly and Dr. Mack couldn't have been more informative. She answered all my questions with honest feedback. I'm looking forward to future visits with Dr. Mack!
I had a great visit with Dr. Mack. She seemed confident when she saw me and got right to the issue at hand. I look forward to getting clearer and brighter skin with her!
Dr. Mack is a wonderful dermatologist. Her office is easy to get to, modern, and comfortable. The staff are very nice as well. Can't recommend enough!
Lian was really personable and knowledgeable. I had a very good experience and would highly recommend her
Dr. Mack was pleasant and thorough. I'd definitely recommend her!
Dr. Mack is a very nice and professional. I came back a few times for annual checks - an old client from her old practice. I send my wife to her practice as well as two good friends. Her administrative team is a whole different story though. They charged my card for a product without my permission. No one told me that I'm going to pay for this and no one mention any price to me (I thought they are billing my insurance for this). My receipt stated a much lower amount for the copayment but it didn't bother them to charge my card a much higher amount. After I called them, they said it was their mistake for not telling me anything about this because the secretary was busy with other things. I understood but asked for an immediate refund. They refused until I will come back to the clinic to return the item. I said that I can only come next week but they refused to send the refund until I showed up there with the product. What a terrible way to treat an old client just to keep their money for a few more days... If you don't want to deal with very annoying administrative people you should not go there at least until Dr. Mack gets more reliable staff.
Dr. Mack is kind, patient and thorough. She does not seek to rush you out, or provide blanket solutions like I have experienced with other dermatologists in the past. The Glamderm atmosphere is an incredibly refreshing, contemporary setting which immediately puts you at ease. You can't help but feel like you are making all the right choices in life by choosing to go there! One thing is for certain: you are in good hands.
Love Dr. Mack. She's very realistic and honest which I appreciate. She's a very kind and empathetic person. I love that I didn't feel rushed at all in her office. She was very attentive and sensitive to my specific needs. I highly recommend her.
very professional. friendly while explaining in detail thoughts / diagnosis. nice staff, modern and clean office will definitely be back if needed.
30 minute wait time :( other than that it was good.
Fantastic as always. Ultra-professional, incredibly friendly and a pleasure.
Dr. Mack was very friendly and willing to answer all of my questions. She's great!
she was very professional and thorough
Dr. Mack was extremely professional and knowledgeable, I had complete trust in her ability to answer any questions I had and provide recommendations for treatment. She was friendly and took time to listen to my concerns. The office staff were friendly and I was seen right away upon arrival.
Excellent experience. She was knowledgable and best of all no wait to see her.
I had a great visit. She answered all my questions and concerns and I will recommend her to all of my friends. This was my best dermatologist visit ever.
Dr. Mack was very professional and knowledgeable. I like that she took the time to translate the medical terminology used to direct her assistant to take notes for my records.
Doctor Mack is great. She is highly professional and capable, and incredibly supportive.
Wonderful bedside manner and made me feel very comfortable!
I enjoyed seeing Dr. Mack. She was very knowledgeable and made some great recommendations for me. As a woman of color it was important for me to go to a doctor who understands a brown skinned person. She explained everything very well scientifically and in layman's terms. I will definitely be seeing her again.
Office is modern and nice. Dr. Mack was very kind and professional
The atmosphere, location, bed side manner is impressive. She had the answer for every skin care concern and or question I had. All with a smile and sincere concern, she eased my embarrassing state of mind. Lian and her staff are Awesome!!
Dr Mack is great! I highly recommend her. Smart, quick, and very attentive. I will consult with her again in the future whenever I require any dermatological attention.
Dr. Mack was fantastic. I expected her to be extremely professional and knoweldgeable and she didn't disappoint, but it was really nice that she was also warm, personable and dare I say funny. Her staff was also excellent.
Easy, no stress, and exactly the results I was looking for. The office staff were really friendly and got me in and out quickly.
All around great experience. Everyone in the office is efficient, professional, and personable. Will certainly go back.
Dr Mack was terrific! Today was my first visit but I now consider her my long-term derm doctor. She is friendly, her office is super clean and welcoming, her staff is nice, and you feel like you're in very knowledgeable hands in Dr. Mack's care.
Dr. Mack and her team are professional, friendly and quick. Highly recommend!
She was very brief but I suppose my visit warranted just a few minutes since I was there to get a second opinion.
She was super attentive and explained the entire process of the screening I was undergoing. She did so without my asking and it was very helpful and informative. I would highly recommend her on the basis of her professionalism and friendliness. She happily answered the plethora of questions that I have brought along with me.
Great Doctor, unbelievable bedside manner. Very nice person.
She recommended blood work even though I didn't need it. It was quite clear to me that she wanted to make a profit rather than be concerned of a patient's well being
I was seen immediately and Dr. Mack was quick and thorough with the skin exam. She explained everything in full and her staff was great.
The clinic itself is very clean and modern. Dr. Mack always makes me feel comfortable through difficult procedures, and her staff are friendly and engaging (unlike other offices where people look like they hate being there). I've only been coming for treatment of plantar warts, but I would definitely come back for other derm-related concerns!
Highly recommend Dr. Mack!
She was so sweet and knew what she was talking about. Quick and easy! Totally recommend.
Wow! And I mean that. Dr. Mack is really fantastic. She immediately understood concerns with my skin and was able to prescribe a routine that, three months later, has changed how my skin looks. She is quick and efficient, but also listens, and her staff is lovely and friendly. Not that it matters, but I also love the modern and sleek look of her office. I highly recommend Dr. Mack, she's someone I'll keep seeing for sure.
First time I've dealt with DR Mack and she was exceptional. Her assistant Nicole is great too (I've seen her twice), but to have the actual DOC. Be as , if not more pleasant than her staff if is amazing. Will recommend.
She was patient, informative and professional. She is the first dermatologist that I have been to that spent more than 5 mins with me. My husband will be making an appointment with her next. I highly recommend Dr. Mack!
From the moment you enter the practice to the moment you walk out the door, the professionalism and warmth you are met with is beyond remarkable. The staff was not only engaging, but very knowledgable. Dr. Mack, took her time to go over everything, field questions, and most importantly, provide honest feedback! The overall visit was what all offices should strive for.
Dr. Mack took care of me very quickly, thoroughly, and with a great bedside manner. Made me feel comfortable talking about a an uncomfortable subject. Had an assistant take down notes for me so I could remember all her instructions and was very down to earth– she understands how frustrating dealing with insurance can be and cared about getting me meds that are affordable. I hope that what she prescribed works, but either way I'm looking forward to my followup in six weeks.
She was very sweet and thorough, and spent a lot of time answering my questions. Will definitely go back!
I liked that she advised against expensive solutions, recommending and explaining why alternatives made more sense for my skin problems.
Dr. Mack is one of the few doctors that actual listens and takes her time with you. She and her staff are wonderful!
Very happy with my visit to Dr Mack. Went for an annual skin check and recommendations for acne problems. She provided a thorough assessment and the medication she prescribed worked. Her office is clean, and staff was very friendly. Will be returning next year.
I am a nervous person when it comes to doctors. dr Mack pit me at ease immediately and took her time with all my questions. I've already recommended her to several of my friends and my appointment was just a couple of hours ago.
The visit was great! I was a bit nervous going in, but Dr. Mack and her staff made me feel comfortable. I highly recommend this practice.
She has the right balance between knowledgeable professional and sympathetic healer. I was very happy with the visit.
Dr. Mack is really nice and very calming. The office is really pretty and her staff is great; I was seen almost immediately after finishing paperwork. As far as bedside manner, I was concerned about something I didn't need to be concerned about and she addressed it quickly, without seeming like she was rushing. I absolutely plan to continue seeing her for all of my skincare needs!
Great bedside manner! Explained everything and what it means. loved her and would recommend to friends!
Dr. Mack is thorough, professional, and has a pleasant and knowledgable staff
I have been a patient for many years and followed Dr. Mack to her new practice . I will follow her anywhere ! I am a complicated case & her skill & care is the best I've ever had . She is patient , empathetic and positive. Her office is beautiful and staff top tier. She truly practices the art of healing. I can not say enough about Dr. Mack & recommend her anytime I hear someone needs a dermatologist.
Electronic forms are awesome! And both the nurse and Dr. Mack are super nice! Best, Scott
Warm welcoming reassuring and straightforward.
She was amazing! She answered every single question I had.
I went to Dr. Mack for my first skin check. She was friendly and more than willing to answer all my questions. I highly recommend.
Dr. Mack is knowledgeable and professional, as are all of the office staff members that I have encountered. I would highly recommend her to anyone seeking an experience dermatologist.
Dr. Mack is personable, highly professional and has a well run office. She has excellent credentials, and provided a clear explanation of my general dermatological condition, as well as her recommendations for treatment.The office atmosphere is inviting with friendly and efficient office staff. I had a wonderful experience. I highly recommend Dr. Mack.
Very professional while still being very nice. She listened carefully to what I had to say and answered all of my questions. No waiting time either and the office is gorgeous, feels very clean
Dr. Mack was special in that she explained things that previous dermatologists did not. I appreciated the information and her thorough, considerate approach. I will definitely be coming again.
Literally the best doctor experience I've ever had. Booked last minute, very friendly staff, 0 wait, thorough diagnosis and recommended treatment
Very clean and modern office. The small size feels comfortable. The owner of the practice met with me on time. The office leverages contemporary technology to stay organized with appointments, and notes, which was great. She seems very knowledgeable in her field. She didn't introduce herself when entering the room, and seemed like she was in a rush to complete our consultation.
Lian Mack was professional, informative, and helpful! I already have a return visit scheduled.
Professional, knowledgeable, in and out
Friendly staff, clean and modern office, very efficient and made me feel comfortable.
Beautiful office and beautiful staff. Everything was great. I highly recommend seeing Dr. Mack!
As I said before I would recommend her to others. She is great!
The office is beautiful and the front desk was great. Just be aware that you have to schedule a full body mole check separately!
It seems she specialize, as is the case with many NYC dermatologists, in cosmetic procedures.
The office is beautiful! Dr Lian was very professional and sweet. She gave examples of products that she uses everyday. I had to wait about 15 minutes but not bad compared to other doctors! Will definitely go back
I just didn't feel super taken care of. I actually shyed away from asking some of my questions because I felt like I was being a burden...
Dr. Mack is very professional and conscientious, she is the best! Today I had a quick follow up and I was in and out in 30 minutes.
Dr Mack was very nice, informative and answered all of my questions. She knew what my rash was, and left me feeling comforted about my symptoms. Would definitely go back to her for any skin issues in the future.
I waiting for just ten minutes and the entire experience was a breeze. I hate going to the doctor but this experience went quite smoothly. Highly recommend
Wonderful dermatologist who listens to any and all concerns!
Dr. Mack and her staff are amazing! I had a few issues that were examined, diagnosed and taken care of in about 15 minutes. I was very comfortable and absolutely blown away by how quickly I was in and out of there, with a job well done I might add. Definitely use Dr. Mack as your dermatologist!
Very professional office staff. Dr.Mack is an excellent dermatologist and I feel very comfortable and pleased to have her taking care of my dermatological needs. I will highly recommend her to others. Hazel C
She is absolutely the best!!!
Dr. Mack is always on time and gives great medical advice. More importantly she is so sweet, makes me feel right at home, and always remembers me by face. I've already recommended her to others!
I loved Dr. Mack and her assistant. They were very personable and thorough and the office was clean and beautiful. Dr. Mack broke down all the medical jargon for me so I could stay informed throughout the appointment which I really appreciated. I will definitely be back to see them again. I did have to wait a little while to get in and noticed they took a girl with a 10:30 appointment in before me even though I had a 10:15 appointment. She may have been meeting a different doctor though, but some kind of check-in from the receptionists would have put me more at ease.
Very professional and courteous staff. Dr. Mack was thorough and efficient, not to mention very friendly!
Dr. Mack's office was the cleanest and nicest office I had visited so far. The staff at reception were genuinely friendly and helpful. Dr. Mack was informative and attentive and very friendly and professional. I would highly recommend her and the office to anyone!
The doctor's office was very small but decorated nicely. I was able to fill out all of my forms in advance of the appointment so when I arrived I only needed to sign a few documents. Having done everything in advance this helped to speed things along. I was in and out of the office very quickly which was great! Dr. Mack was kind and listened to everything I said. She also has amazing skin herself which always makes me feel confident in a doctor that is supposed to help with mine!
Wonderful experience. So much better than any I've had before in NYC. I was in and out in under a 1/2 hour. My issue was addressed with superior knowledge and attention.
Very quick. Super professional. Fantastic bedside manner. The entire visit was excellent.
Professional, efficient and friendly. All I was looking for!
Her new office was so beautiful and welcoming. I was impressed with her bedside manor and she was very efficient! All staff was quick and professional!
I truly enjoyed my visit with Dr. Mack. The office is beautiful, and the staff are friendly, and engaging. Dr. Mack was courteous, professional, and my course of treatment was very straight-forward, and easy to understand. I've already recommended her to several of my friends.
Dr. MACK knew her stuff. Loved her awareness about the skin concerns of people of color.
I found Dr Mack through Zocdoc and was encouraged to see her based on the great reviews, for my acne problems. She is very kind, professional and knowledgeable. I would say she instills great confidence in the treatment plan we followed. Acne is a condition that takes time to cure, Dr Mack urged me to be patient for a couple of months and I am glad to say she was right. Three months later, my face is almost acne-free and my skin looks great.
Dr. Mack was very professional. I didn't have to wait at all. Stuff was friendly too. Answered all my questions and concerns. Highly recommended.
I have recommended her to a co-worker. She is awesome. I am happy I went to her.
Dr. Mack and her staff are amazing! Very knowledgeable and pleasant. Better than what I had expected.
I was so scared coming into this appointment. Dr. Mack and her team put me at ease, and immediately made me feel so much better! Have found my long-term skin care doctor. Thank you so much!
Didn't seem to take my concerns seriously after realizing that I wouldn't be interested in purchasing any creams.
I came in for a body scan and to make sure I am generally taking care of my skin properly. Dr. Mack was both very thorough and still efficient when checking for moles or anything abnormal on my skin. While checking my skin, she explained the type of mole/freckle/blemish and her assistant noted everything down. She did not even mention let alone try to push any skin products (which has been my experience before), but if I asked for her advice on anything specific she was a wealth of knowledge. I feel confident that I am in good hands with Dr. Mack with respect to maintenance and protection of my skin from an aesthetic perspective as well as from a health and safety conscious perspective.
Very informative and caring. Great staff!
Very nice and informative Doctor. Her office space is also really clean and spacious.
Absolutely great! Have already recommended her to all of my friends! Will definitely be going here again!
Dr. Mack was excellent! She was extremely friendly and approachable, and explained exactly what she was doing and looking for throughout the checkup. She also went out of her way to define medical terms and highlight what I should and shouldn't be concerned about between periodic visits. I also appreciated her recommendations for specific products to use for my skin type and concerns, and how she preferred to have all of my prior dermatologists' records and pathology results forwarded for her to review before making any decisions on procedures.
I enjoyed my visit with Dr. Mack. She was thorough and explained everything that she did/recommended. She gave me samples for the acne medication that she recommended, which I was very appreciative of. Much better to try something first than to get the full bottle only to realize it doesn't work! She also had some up-sells that she recommended for my condition but suggested starting with the sample medication first. Very nice to not feel like you're being taken advantage of so that the doctor makes more money :) Highly recommended!
She's very smart and warm. And found that we both like the color purple. The office was very relaxing and the staff were very friendly. Highly recommend her service.
As always, it was quick and Dr. Mack and her staff were great. Always a pleasure.
I loved the office - it was bright and well designed.
Dr. Lian Mack was amazing. She is the epitome of patient centered care. Detailed oriented and extremely knowledgable.
I'd give Dr. Mack 10 stars if I could. From the incredibly cheerful lady at the front desk, to the attentive and charming assistants, to Dr. Mack herself, this was truly one of the best doctors visits I've ever experienced. What was originally a consultation turned into Dr. Mack going out of her way to squeeze me in, taking care of my problem in a matter of minutes, and sending me on my way with mountains of stress lifted from my shoulders. I cannot recommend her highly enough. Go here.
Very through and explained everything well. Process was super easy!
Dr. Mack takes the time to explain everything she is noting, which is very helpful.
Dr.Mack makes your doctor visit a luxury experience!
Dr. Mack and her office were incredibly helpful through the entire process. I have recommended her to all of my friends. You are in the BEST hands with her. Thank you!
Dr. Mack has a beautiful office and a lovely staff. She is warm and thorough and offers a wide range of services - perfect for all my needs!
Everyone at this practice was so kind and helpful! Will definitely be returning.
Very friendly and quick to diagnose.
Dr. Mack and her staff are all kind, friendly, and knowledgeable. I appreciated her sensitivity toward insurance plans and clear explanation of how everything would be billed. Highly recommended.
Dr. Mack was professional, kind, and efficient. She knew the brand of treatment best for me off the top of her head, and the entire appointment took only 20 minutes.
She's simply fantastic. Talented and a pleasure as well.
I absolutely love Dr. Mack! I moved out of state and still return to see her. She is sweet, empathetic, and knowledgeable. The office and staff are also fantastic.
Dr Mack is wonderful--she is super sweet and gentle, talks through everything as she is doing it, always making me feel very comfortable. She is very skilled and I completely trust her.
I was very comfortable. She is lovely, with a very professional, knowledgeable and confident. I was happy when I left there. I am almost sure she will help me. Thanks Doc Zoc !! Jeannie W.
Dr. Mack was very knowledgeable, professional, and courteous. Unfortunately she couldn't help my issue, but it wasn't due to lack of ability. When it comes to skin/hair some things are just not medically treatable or covered, even if they are. I liked her better than my previous dermatologist, and if I worked closer to her office, I would return again.
Dr. Mack was soooo great. I chose her because, as a woman of color going to her first dermatologist, I wanted to choose a doctor of color that would have a personal understanding of treating skin of color. As she's checking me out, she would use an acronym and then actually explain the acronym, I learned alot about the moles on my skin. The skin screening was very thorough, I honestly felt like she was just going to look at my face and maybe at a couple moles I was worried about, but she checked everything and I felt very comfortable. 5 stars 5 stars 5 stars!
Everything done just right.
No wait time, answered all of my questions clearly and patiently. Thanks, Doc!
The office was very pleasant and Dr Mack had a great professional manner.
Got me in right away. Explained my issues very accurately, and now 1 month down the line treatments have been on point. Excellent visit and highly recommended.
Very good experience
Dr. Mack is the best Dermotologist in NYC. She has a beautiful office, friendly and smart staff. Needle in a haystack.
I left that office feeling amazing! Wonderful & personable staff and doctor!
My consultation was great & informative. I'm looking forward to trying the regimen she recommended.
Dr. Mack is very personable, professional, and knowledgeable. You will certainly appreciate her manner. I strongly recommend her.
She was a sweetheart. Very friendly and very understanding and knowledgeable of my unique skin condition. Will definitely recommend to anyone I know who needs a dermatologist!
Dr. Mack was great. I was concerned about some recent and sudden hair loss that a prior visit to another dermatologist left me with an alopecia diagnosis and possible debt over cortisone injection sad a treatment. Dr. Mack took the time to explain everything and had suggested I'd get blood work done before any diagnoses were given instead of just jumping to the easiest thing she could diagnose. Overall very knowledgable and caring.
The visit was great, exam was thorough and Dr. Mack has a very pleasant office team. Great impression for a first visit and new patient.
Very thorough. Beautiful office. I didn't feel rushed at all. Dr. Mack made sure I understood the reason behind my complaints and the treatment I was being put on. Will definitely return.
I wanted to wait a few weeks before I commented on the prolonged results of treatment and more than one month later I am STILL beyond thrilled with my first visit to Dr Mack's practice! Her practice is intimate, centrally located and convenient, and beautifully decorated. Her front office team made me feel as though I was the only patient of the day, catering to my needs and answering questions with a smile. Great customer service! The check in process was extremely easy with minimal paperwork. My visit with Dr Mack was thorough yet efficient. We discussed multiple options for the day and my follow up visits. She made me feel EXTREMELY comfortable, is very knowledgable, and even discussed cutting edge treatments I never heard of. She has an eye for aesthetics and clearly outlined what I should expect in the weeks to come. Her approach is not pushy at all which I appreciate having gone to other derms that only want to sell their products. Thanks to her and the team. I will definitely follow up with my skincare needs at GlamDerm.
Dr. Mack was fantastic. Felt like I was going to see my friend who was a doctor - I am happy to have finally found a dermatologist who has an organized and efficient practice!
Dr. Mack and her staff were great. I was very comfortable the whole time and I was in and out of the office within 30 minutes.
One of the worst dermatology visits I've ever had. The doctor was not helpful at all and ended up billing me a lot for a "small procedure" she did without fully explaining the costs of it. She also kept pushing for future procedures that I was not comfortable with, but did not suggest anything less aggressive. In addition, the receptionists were also rude. I will never recommend this practice to anyone.
My visit with Dr. Mack was excellent. She is very knowledgable and explained all the options to me in a way that was understandable. She also answered all of my questions and made me feel as though they were all important questions. On the next visit she even made sure that the other physician was supported by her and available if needed which made the entire process, being my first time, feel extremely comfortable.
Dr. Lian Mack, MD is very knowledgable and very thorough in her examinations. The office is very clean and makes you want to come back. My skin is on point because of her! I would recommend Dr. Lian Mack to everyone.
The reviews I read about Dr. Mack are true. She is really great and knowledgeable. Perfect for a lunch hour appointment if you're just looking for a check-up/consultation. She educated me on some issues with my skin in a very clear way and gave me a few options. The lobby is also very clean and welcoming. I will most definitely go back.
Wonderful bedside manner, friendly staff and a nice, clean office. I Highly recommend!
The office is sleek and fabulous. Customer service was top notch from the time I walked in the door up until I left. Dr. Mack was kind, informative, patient, and took her time. Her skin looks great so this gave me confidence that she could help me look fabulous as well. The staff were friendly and made the check in process quick. I left with a smile and recommend anyone that needs a great cosmetic dermatologist to visit this practice.
Dr. Mack is awesome! She's just started her own practice, and I think it was a great move for her. I'm glad I followed her over. She is incredibly professional but also very personable. I would highly recommend her!
Dr. Mack was very professional and answered all of my questions. Looking forward to going back for other services.
Dr. Mack was very professional and very informative during my appointment explaining every step of the process. Great doctor, I will definitely recommend her to family and friends.
I am a previous patient of Dr. Mack's from her old practice, and have followed her to her new private practice because of her professionalism and excellent provision of care. I would highly recommend Dr. Mack!
Very personable and honest
Dr Mack was fantastic - very nice and did a thorough annual skin exam. Highly recommended!
She was lovely. Answered all my questions & made sure I was satisfied before ending the appointment. She didn't try to push any products on me that I didn't need. I would definitely recommend her.
Dr. Mack is very thorough and personable. She is warm and makes you feel comfortable with any questions. She takes the time to explain things thoroughly and her reasoning for giving you a certain treatment. She also works with you to give you samples and coupons and find treatments that work for your price range. All I could ask for in a dermatologist!
Very professional. Explained everything to me and very informative!
Dr. Mack told me that the acne on my forehead was ONLY treatable by a surgical facial that was not covered by insurance. I pushed back and asked if there was any topical I could try because it was a lot for a student to cover. I was told 'no,' but went to sephora anyway and got some fancy face wash, and, lo and behold, the acne that had persisted for a year cleared up within a week. Maybe this office is better for cosmetic procedures, but it felt transparently self-serving.
I've been a patient of Dr. Mack's for 4 years now and have followed her to three different locations. Yep, she's that good. Very consultative in her approach, is passionate about her work and the science behind it, oh and her new practice is gorgeous! Just like your skin if you work with her.
What a great doctor! She took my concerns seriously, immediately presented me with a treatment plan with several options, and all around just gave me a lot of confidence both in her and in what I'll be using. Excited to see results!
Really lovely office and really lovely staff. Dr. Mack is quick, personable and professional. Oh- and there is free chapstick. The nice kind. :)
The Dr. was good but they told me that they accepted my insurance when in fact they do not. Few weeks after the visit I received a billed for "Out of Network" services. I had to call ZocDoc & her billing dept to get the issue resolved. Ultimately, they removed the out of network charge. I was a bit annoyed that it happened in the 1st place. I would encourage anyone using this service to confirm with the Doctor's office that they accept your insurance. Usually ZocDoc is spot on but it doesn't hurt.
Dr. Mack is very professional and also friendly. She listens well and responds. Most important she is very careful and thorough. Jim F
Cool office. Nice staff. Great doctor.
great experience all around, highly recommend.
Have been seeing Dr. Mack since first visit at Chelsea Skin and Laser earlier in the year. Very pleased and happy with her treatment thus far; she is professional and knowledgeable. Very comfortable with her.
Dr Mack is great! Awesome Dr. with a sense of comfortability and knowledge of her practice. I felt like I had been going to her for months even though it was a first visit!
1. I love Dr. Mack's office. 2. Front desk staff super helpful and nice. 3. Dr. Mack is amazing! Unfortunately, I am no longer based in NY so I had to give up the commute.
Doctor is very professional and kind, treatment was very effective!
I had a very embarrassing skin issue in a very embarrassing place, and she made me feel totally comfortable about it. We had a good laugh, and she gave me great advice, and my skin cleared up pretty quickly.
I love, love, love Dr. Mack. She's super nice. I felt very comfortable with her. She took her time and answered all my questions. Everyone in her office was very friendly.
Friendly office staff, on time appointment. She took time to explain different options. I would highly recommend!
Dr. Mack was thorough and thoughtful. Her staff was also very nice.
Dr Lian and her staff were very nice. The office is beautiful and clean, very modern and pristine. I didn't have to wait to see the doctor, she was really personable and knowledgeable. We got the point very quickly and I left with my question answered. I would definitely see her again and recommend her!
Really great and professional. Took the time to explain what everything meant to me. Was very thorough.
Dr. Mack is superb. She is knowledge and able to build trust. The staff working in her practice are also very professional.
Could not have had a better experience. On time, easy check-in, very friendly and very knowledgeable. Look no further if you're searching for a great dermatologist.
Love Dr. Mack! Her and her staff are available whenever you need!
Dr. Mack and her staff were extremely professional and knowledgeable. The office was really clean, modern, and welcoming. Highly recommended and I'll definitely be back soon!
Dr. Mack always makes me feel welcomed and comfortable during my visits. She maintains an awesome aura, positive attitude, and genuine smile. Her staff is very thorough in follow through as well. The new office is coming along very nicely to add! I will definitely keep her as my dermatologist, no matter where she goes!
Dr. Mack could not remember seeing me before. She listed incorrect ailments and treatment, which I was honestly happy to correct. What really irked me was her prescribed treatment, which ended up aggressively worsening my condition rather than fixing it. When I went back and showed her, she was convinced I needed to stick with it. I ended up picking a new dermatologist.
Dr. Lian was great! She was very sweet and saw me in under 15 minutes. She also was able to recommend different options for me and even mentioned a few other doctors that could also be helpful. Would highly recommend.
Efficient, friendly, and thorough skin cancer screening. No wait to see the doctor, and she explained everything about various moles and other spots.
Dr. Mack was very professional and knew her stuff! I would highly recommend her!
Super thoughtful, personable, educational, and thorough. I had been to a few other dermatologists before visiting her and I really appreciated her help.
Great Dr.! Very approchable and informative! The staff is also very nice. Definitely recommended.
Dr. Mack was excellent. Most thorough dermatology exam I have ever had.
She was very sweet, engaged, knowledgable and informative. And, of course, her skin is AMAZING. I'm trying to get on her level!
Dr. Mack was fantastic. Knowledgeable, to-the-point, and friendly. Happy to have her in the neighborhood.
I am a new patient of Dr. Mack's and I've had nothing but a great experience from the beginning. Dr. Mack was very helpful and responsive to my emails prior to my appointment. Once there it was a quick wait until I saw her, just because of new patient paperwork. She was very thorough and explained medical terminology along the way. She took the time to answer any questions I had and offered her best medical opinion. I intend to continue seeing Dr. Mack as she made me feel very comfortable and not rushed at all. (Her office is going through some construction at the moment but that didn't interfere with my appointment - I was there was an annual skin screening)
Thorough and Clear, nothing short of efficient as well as patient to answer any and all questions.
Very personable and knowledgeable. She was able to work with me and my expectations for acne treatment. I haven't had any acne since finishing my treatment with Dr. Mack. She's great. Highly recommend!
She was great. Easy to talk to and explained things well.
She is wonderful and always very helpful.
WOW. What a kind and cool woman. Everyone in her office was the same. I cannot recommend enough
My last visit with Dr.Mack was excellent. Dr.Mack is very personable and is always attentive to any concerns you may have. I highly recommend Dr.Mack. Thus far she is the best dermatologist that's truly cares about her patients and is always accessible.
Dr. Mack and her staff are very professional. The office is new and conveniently located near a major subway stop.
Friendly, professional and efficient.
Dr. Lian is knowledgable, direct, and very friendly. I followed her from her previous practice to her new self-run office in Gramercy, even though I live on the west side!
Dr. Mack is wonderful. She was patient with me, and took time to explain what the implications of my minor procedure were. I highly recommend her.
Dr. Mack was very thorough, attentive and answered all questions I had regarding my diagnosis. She also followed up quickly after testing and gave a detailed analysis of diagnosis. I highly recommend Dr. Mack.
She is simply the best Dermatologist in NYC. Im so glad she's been my doctor for years.
Dr Mack is nice, smart and friendly. The office staff at GlamDerm is amazing and I feel so well taken care of when I'm in the office!
Very pleasant, confident, and answered my questions and concerns.
Dr. Mack was so thorough and informative, just like the reviews on here said. I came in for a routine skin checkup that I had been neglecting, but she also helped me with other issues she saw. I've seen Doctors before that will only help you with the specific reason for why you're there, but my visit was really comprehensive and I couldn't be happier. Highly recommend!
Dr. Mack had a great bedside manner and explains the procedures she performs in a way that is both comprehensive and understandable. The issue I have with this office is that for both appointments I booked (initial and follow up), I had to wait almost 30 minutes past my appointment time to see the Dr. even when other individuals who arrived later were taken back first. The staff apologized for the wait but as this has happened twice, it seems to be the norm.
Beautiful office. Great service. Short wait. Dr. Mack is an utter rockstar. Very knowledgeable and caring. So glad I found her.
Dr. Mack is extremely friendly and knowledgable. She is patient and takes her time to explain all solutions available.
Dr. Mack was great! She was thorough yet to the point. She explained everything she was doing - very smart, competent dermatologist.
Great first visit! Was seen very quickly, felt like Dr. Mack really addressed my issues!
Dr. Mack was incredibly knowledgeable and personable. I felt at ease immediately. She quickly and correctly assessed my situation, reviewed past medications/treatments, found a better solution and described all of the possible side-effects and implications in GREAT detail. I feel incredibly confident that I have gotten the best solution and most comprehensive treatment possible. She even scheduled a follow-up and gave me a full run-down of how the treatment will progress and future steps. She is a rare find.
I love Dr. Mack! The ratings are on point. This was my first time visiting her and I will definitely be coming back. The wait time was reasonable. Her staff was very friendly and her best side manner was awesome. She answered all my questions and this was the first time visiting a doctor, that I didn't feel rushed!
I absolutely loved her. She explained what she was doing, was thorough, nice...great all around.
Best dermatologist in New York! I flew in from Europe to see her-THAT good..
Thoroughly impressed, definitely would recommend.
Phenomenal consultation, lovely woman.
I was 5 mins early for my appt and they took me right away. Dr. Mack explained everything, did the treatment, and I had paid and left in a total of 15-20 mins. They don't make you feel rushed, just are efficient and you're never waiting. Dr. Mack has a very calming presence and way of explaining things. She called me herself to follow-up. 100% recommended.
Got a quick but thorough annual screening. Dr. Mack explained everything she was doing and looking at and kept me at ease.
Thanks to Dr. Mack, my partner and I were able to catch a bed bug problem and get in under control super early. Other dermatologists told me what I had were simply hives, and prescribed anti-histamines. Dr. Mack correctly identified that my bites were actually bug bites, and she strongly recommended getting an exterminator. Her hunch was verified when the exterminator came the same day. Thank you so much Dr. Mack!!
Dr. Mack is caring and practical. She has an easygoing bedside manor and makes sure she handles all of my concerns.
Great doctor! Took her time to check all of my moles and explained clearly the medical terms she used.
Dr. Mack is an excellent practitioner. She's clearly passionate about her work and genuinely wants to improve your skin's health. I appreciate how she discussed my issues from a technical point of view and also spoke to me like a human.
She is amazing!
That was my first time ever to see a doctor in the United States. I am impressed with the service provided by Dr. Mack and her assistant, Joan. Pleasant room and a plenty of time to discuss my medical conditions with both of them. I want to go and visit them every day but I don't want to get sick :)
Highly reccommend Dr. Mack!! The overall experience was better than most doctors visits and she was informative and knowledgable.
She was very nice. I found her very professional and her bedside manner is great. She did not push procedures on me I did not want. Just answered my questions.
Dr. Mack was very informative, patient and really pleasant. She took her time with me, addressed my concerns and really made me feel at ease and important.
Dr. Mack was amazing! This was my first time visiting a dermatologist, I came in for an annual skin exam and had a few questions regarding changes in my skin and Dr. Mack took her time with me --she was very informative and answered every question and concern I had. I highly recommend her, she will definitely be my go-to Dr!
My time speaking to the doctor was literally 5 mins. She was nice, but this was a rushed appointment. Spoke mostly to her assistants. I'm not sure if I'd return.
This was such a great experience. Dr. Mack was so helpful and enlightening- I left completely informed and understanding the steps I need to take. I was taken in right on time, which worked out great for me to get back to work on time. I would highly recommend her to anyone looking for a wonderful Dermatologist
Fast and easy. Very personable, gave clear explanations for all notations made during the exam.
Professional, great office, nice staff. I was in and out in a jiff
Dr. Mack was amazing - quick, very knowledgeable, and not judgemental...would highly recommend!
Knowledgable, personable, just a great, easy experience. I highly recommend DR. Sorhaindo
Very thorough and explained everything in detail.
Dr. Mack exceeded all my expectations when I came to see her for a cosmetic procedure. She took her time and explained in length the full scope of the treatment. I felt completely comfortable and incredibly well taken care of - and loved the result!! Told all my girlfriends to go see her....
She was great, thorough, answered all of my questions and there was no wait time.
I am very pleased and looking forward to returning! She is very pleasant and informative.
I went to see Lian A. (Sorhaindo) Mack, MD, for the first time today. She was fantastic! Very pleasant, sweet, took her time to answer all of my questions and concerns. I never felt rushed at all. The office itself is very zen & spa like. Front desk staff was nice & efficient. I would highly recommend her and I am looking forward to my next visit.
It was great! Dr. Mack is extremely kind and informative! I highly recommend her.
Came in to see Dr. Mack for my very first dermatologist appointment ever. I have pretty clear skin but was having breakouts on my back and chest. Dr. Mack did a full scope of my entire body. I have a handful of moles on my body that I have never checked out and I was very happy she did a scope because I was worried some of them could be a problem since they were elevated. She told me everything looked normal and did write me two scripts for my breakouts. I was very pleased with my visit, she is very professional and sincere. Would absolutely recommend!
Really great experience all around!
Great experience, nice staff, thourough exam and she explained all of the terminology she was using. I was seen within 5 minutes of checking in.
I will not be returning. I found her to be unhelpful, and after I waited for an hour in their lobby, she did not come up with any solutions to my problems. I was already self-conscious when I arrived at the office with my dermatological condition, and only left more so.
She was very thorough and explained everything so I could better understand. My skin looks amazing now!
She was very knowledgable helpful and understanding. One of the best doctors I have gone to. I highly recommend her!
My appointment with Dr. Mack was great. The office is very stylish and almost spa-like, with friendly reception staff and I only waited about 2 minutes. I was there for a skin exam, and she checked me very thoroughly making notes on all my moles and measuring ones that looked irregular. She also gave me some samples to test out for some persistent acne I've been having. I'm happy that I'm able to try the samples before I pay for the full subscription product and have it not work (like has happened in the past). Overall this office was efficient, welcoming and the doctor gave me solid advice. I recommend them!
Great consultation, great manner and thorough.
Dr. Mack is very competent, professional, and efficient at what she does. I couldn't be more pleased.
Promt. Thorough. Thoughtful. Helpful. Couldn't ask for a better experience.
First, Dr. Mack is great. She made me feel very comfortable and answered all my questions. She even addressed my concerns about my prescription before she placed it and without my even remembering checked my moles and gave me literature on what to look out for with them. Her office staff is also exceptionally friendly! And her location near my workplace is perfect for me. I'm very happy that I found her.
Was everything I had hoped for in a visit to a new dermatologist!
Great first visit with the doctor. Highly recommend.
Dr. Mack was a great experience. She was very thorough in her skin check and explained everything that was happening as she did the exam. Her office was very professional and I was seen right away. I highly recommend her.
Compared to other dermatologists I have seen over the years, she was more thorough. Dr. Mack was pleasant and very efficient.
Clean office, friendly staff and Dr. Mack has a calm, smart demeanor with me.
Dr. Mack was really great and professional. She was patient and answered all my questions. The Staff was also wonderful and very friendly. I would definitely recommend Dr. Mack to anyone.
Dr. Mack was timely, thorough, and answered all my questions. I would recommend her to others.
Anxious to go back in September.
So happy with Dr. Mack. The office is beautiful, and they make sure to stay on time. All the staff was friendly, and Dr. Mack herself was wonderful. I was there for an annual skin screening, and she was thorough and explained everything as she went along.
Love Dr. Mack! Super sweet, honest, understanding, and helpful. I would recommend her to everyone.
Very lovely. She and her assistant were very helpful and thorough during my visit. I look forward to continuing to work with her.
Very thorough, knowledgeable and to the point. Appreciated that I was seen so quickly and she made sure to take the time to see if I had any questions on anything. Definitely will be going back!
She was extremely nice and attentive, very professional. She was able to quickly and correctly diagnose my condition and prescribe the proper medication for my acne -- Something I had been struggling with for over 10 years. Dr. Mack is wonderful and I highly recommend her.
Very condescending. Not attentive. Rushed. Terrible work. I will never go back.
The meeting was rushed and she didn't seem interested in the information I provided her with. I spent most time with her assistant that was not able to explain all the different creams that they kept telling me I should get. Based on the reviews I had read on her I was excited to meet with her, but unfortunately walked out disappointed.
My visit was quick and informative. Dr. Mack informed me on the issue I was seeking help with very quickly, putting my fears to rest. She was fast but thorough, and very friendly! My only complaint was the wait – I showed up 10 minutes before my appointment to an empty waiting room. Four people showed up after me, and each was called into a waiting room before I was. I also had to wait a while in the examination room before seeing Dr. Mack, but the nurse was very attendant and apologetic, and checked in on me multiple times to give me updates.
Dr. Mack took her time and helped me understand all my issues and medications. I felt totally informed when i left. :)
I think she was very professional and "listened" to me instead of hearing about my symptoms. She was very thorough and knowledgeable. I would highly recommend her.
She seemed off put by having to examine my condition. Not thorough, not particularly willing to volunteer suggestions.
She is very well spoken, and she really payed close attention to my concerns. She is amazing!!!! Very professional.
