Verified Patient Reviews
The doctor was courteous and efficient. She was attentive to my complaints and concerns, diagnosed my condition after a brief but thorough examination, administered a relatively pain-free injection for my skin condition, and advised a plan for a course of treatment.
Dr. Hammerman saw me a few minutes after I arrived for my appointment. Very knowledgeable, and a very nice person, to boot.
It was a pleasure to see an office so efficiently run. The staff was congenial. I was seen on time which is a first for me in a long time. Dr. Hammerman and her staff were so attentive and I felt that my condition was taken seriously and than addressed fully. Everything was explained to me in a concise and respectful manner. I felt at ease, not talked down to or rushed. I would definitely recommend Dr. Hammerman to my friends and relatives.
She was ok , not very friendly , felt rushed. Had more questions but felt like i was bothering her .
She is good
Very clean place nice ppl and no wait Time loved that she talked me through everything she was doing
I was late...more than 1/2 hour late. Doctor Hammerman still took me in to take a look at me. She is great, and a very nice girl.
She remains to be one of best physicians I have ever met.
Loved her personality!!! very thorough and informative.
Shs was very pleasant and imformative
Dr. Hammerman and her assistant were very professional and took the time to answer my questions. The wait time wasn't bad at all. Will definitely be returning.
Dr. Hammerman is an excellent dermatologist. I highly recommend her!
I arrived a few minutes early and the front desk staff were friendly and welcoming. There was a bit of a wait to see the doctor, but I wasn't in a rush, so it was fine. Things went downhill when I met with the PA, who didn't even bother to look up from her chart to greet me or even to ask questions. Dr. Hammerman came in a few minutes later and she was even more cold and clinical- there was no warmth to her face. As a first time patient, you'd expect to feel a bit welcomed.She did a cursory exam , and sent me on my way. Would never used thisbpractice again. I'll stick to Spring Street Dermatology, even if it's a bit of a trek to lower Manhattan.
Showed up early, but was seen immediately. Most of the paperwork was done online when I made the appointment, so checking in for first time was a breeze. Very friendly, helpful staff. Doctor was professional, and quick, without making me feel rushed.
Would highly recommend. Barely waited in the office/room. Staff was helpful. Dr. Hammerman listened to my concerns and treated accordingly.
It was a great experience. I took my child and she treated her right away. I had taken her to other dermatologists that did not do anything to her and Dr. Hammerman was awesome. :)
Love the service I was in and out and the doctor took enough time to explain everything she needed too. The only con I have to say is leaving the credit card on file and it being manditory. I've been to oher doctors office and work for one and I always seen that it was optional not mandatory. They should really let patients decided if they want to keep their credit card on file for 90 days.
Filled out all my paperwork online, so that definitely helped! Apt was for 4:10pm. Waited about 20 minutes. Was seen by an assistant first. Waited in the room for about 5-8 minutes. Met with Dr. Hammerman. She was very helpful with the diagnosis (eczema). Recommend a few medications and tests that can be done. Requested a follow up soon. Was with her for about 5-10 minutes max. Out by 4:50pm. Would recommend! :)
Dr. Hammerman was professional and very nice throughout the whole appointment. My family and I all see her for our dermatology needs, she is skilled and very knowledgeable in her area of work. I highly recommend her.
Dr. Hammerman was excellent, very kind and took the time to explain everything to me. I found my permanent dermatologist. Recommend highly
I absolutely love her been going to her for years , she is amazing when it comes to skin and she understands you and she doesn't push any purchases on you which is a plus in my book . She is caring and understanding and works with you .
Didn't make me feel comfortable.
I was very pleased. Dr. Hammerman was very professional and personable. I did not feel rushed. She addressed all my concerns. The office staff was also very professional.
She was so nice and professional. Made me feel comfortable and I most definitely will keep seeing her for all dermatology matters
Everyone was,friendly and professional. The receptionist and medical assistant were lovely. Dr. Hammerman was,knowledgeable about what I was,concerned about. Perfect visit.
Always Pleasant, Cordial & Processional -Knows her stuff!
Very knowledgeable and attentive to all my questions
Dr. Hammerman was great. She was very professional and got straight to the point. My issue was resolved at the same appointment. I highly recommend her.
I was very excited to go to my first dermatologist appointment. When got to facility; I was like wow because was so beautiful. My appointment with Dr. Hammerman was amazing because she take her time to listen to you as patient, she very informative on what you should do and how you should do it. She lets you know that going to take sometime but the process worth it. What love about her she told me about my insurance might not cover one my medication; so she gave me options on how should go about the situation. Schweiger have a pharmacy program that will deliever your medication to your house; I can say they wonderful because of them and Dr. Hammerman got all my medication cover from my insurance. If you want great female Dermologist so she Dr. Hammerman.
Very pleasant doctor, made me feel better about a suspicious mole.
Rather not say!
too quick....didn't have enough time to discuss skin issues
Pleasant, professional, helpful visit and doc is very knowledgeable about my medical condition. Also the receptionist in front very helpful and acomodating to all patients. Definitely would recommend to other people to there for their dermo needs.
As always, Dr. Hammerman and the rest of her staff were professional, compassionate, and helpful.
It's been over 24 hours since my appointment and my prescription STILL has not been called in. Every other doctor's office I've ever been to, the prescription is called in immediately so I am definitely not a fan of this, nor was I notified that this was how the office operated. I would've preferred the good old fashioned hand written prescription if I knew this was the case. The doctor, however was great. The check-in process was quick and easy and there was absolutely no wait.
I saw this doctor for about a year. Pros: she seemed generally knowledgeable and her recommendations generally improved my skin. Wait times in the early morning were reasonable Cons: visits feel quick and rushed. Previous dermatologist spent more time examining me rather then waiting for me to say what's wrong. What did it for me was when my prescription got forgotten twice. The first time I called maybe 3x before it got resolved. "We'll call you back" has a 50 50 chance of happening. The second time was way more trouble I waited for a few days for the pharmacist that the doctor recommended to call me with delivery time. They often took a few days so I eventually called. They said they'll call the doctor and call me back. I ended up calling both doctor office and pharmacist many times over the next week before it was resolved. The doctor never sent it over. Eventually some business manager called me to say they would make sure it's done. I had to commute 2 hours total back and forth to the pharmacy to get an emergency pickup so I wouldn't miss more doses. When I saw the doctor the next time, this incident wasn't even mentioned, but I did get upsold on more laser procedures. This was regular, and I get they have to do that, but screwing up the basics, while upselling leaves me with a unpleasant feeling. This kind of behavior hurts the patient/doctor relationship
Very caring , great doctor
Was okay so far good.
Took a complete history and time to determine my issues. Her assistant was also just as thorough. Definitely one of the best physicians I have ever met.
I think Dr. Hammerman seems like a very nice person however she is the worst doctor I have ever been to. Annual skin exam should have taken about 15 minutes but the exam was only 1 to 2 minutes. She said everything looked fine come back next year. She didn't go into any detail and didn't even get a chance to ask any questions and she immediately left. If you're looking for a doctor that cares about patients don't see this doctor.
I'm very impress with Dr. Hammerman professionalism!!! She make me feel very confident and constable.. I looking forward for my next appointment...I highly recommended Dr. Hammerman !!!! :)
Attention to detail Thorough
Dr Hammerman (after reconmmending full body checks every three months) failed to examine the back of my legs on the body check I was there for. After two malignant melanoma diagnosis in three weeks I thought this was negligent on her part.
My visit was very good. Dr Hammerman is professional with good bedside manner.I am on my second visit and does not have a problem. I would definitely recommend her service.
Very professional and all business. She was quick and efficient. Her assistant was also very efficient. I would definitely recommend her to my family and friends.
Dr. Hammerman listened to my sun screen use and had a "no preach" style and I really appreciated that. Waiting for results and keeping my fingers crossed for good news.
I went for Botox AND a body scan (skin cancer runs in my family). I was last patient of day and they couldn't do both. Here prices are on the more expensive side for injectibles. But she was willing to work with me if I did lip filler too (I suggested that not the doc). She is beautiful and has amazing skin and lips. Def go for injectibles ! I go back next week - they give an extra 10 units for free if you need more in 2 weeks! Her staff sucks. But she knows it. Def going back for my lips !
This was an initial exam with this physician and I thought it was extremely brief and not at all as extensive as it should have been. I am not only a healthcare provider, but I have multiple dermatological issues that needed to be addressed. The skin assessment was brief and not all areas were assessed as they should have been. I was prescribed several medications and was told that they were sending these to a pharmacy and I would be contacted by the pharmacy within 48 hrs. I was not contacted so I called the office. After explaining the situation ,I was shuffled between several members of the office staff, finally realizing that no one there knew what was going on. I was then told that the prescription was never sent and that they would send it in at that time. The members of the office staff were curt and not at all courteous. I think perhaps Dr.Hammerman needs to review what constitutes a "thorough" skin assessment. I also think that the office staff need to be educated on how to interact effectively with patients. I will be seeking a new physician for my next exam, very disappointed in the experience.
I am vpleased with my visit. MD K. Hammerman very professional .
She has no knoweladge ....unexperinced doctor I have ever visted, maybe last one... My pcp gave me a copy of my blood report to show her, she couldn't read it the tests....
Dr. Hammerman took less than 5min to examine me. She barely looked at my skin, prescribed me a cream and advised to come back in a few weeks. This has been a very unsatisfying doctors visit. Unfortunately I would not recommend her, even though the staff (nurse) was nice.
I had a nice experience with this doctor and all my concerns were addressed. I also liked that a treatment plan was made up.
Very professional and focused on what was important to me.
Dr. Hammerman is an amazing women who will take her time with you. She is very thorough and conversational, making the visit very casual and you as a patient very relaxed.
Dr Hammerman was really short and not friendly at all. I didn't feel comfortable. I was her last patient and I could tell she was rushing me out the door so she could leave her office.
Very pleasant, professional and attentive doctor.
Dr. Hammerman determined my dermatalogical issue right away and gave me samples in order to treat it. I was given a follow-up appointment in a month.
I am a new patient with Dr. Hammerman. I have been to other Dermatologists before and so far I give her very high grades in every category. She is very knowledgeable, very caring doctor. But the most important thing to me is that she is thorough She caught somethings that other doctors completely missed. Her treatments for me are working well, and I could not be happier.
Dr. Hammerman was great! She answered all my questions and had great recommendations for my skin.
I shouldn't have believed all the hype- excellent ratings on healthgrades, etc + I had been impressed with her credentials + video of her on her website. However, the actual visit was something else altogether. . Firstly, my daughter was in and out in less than 10 minutes! Note, this was her first time seeing dr. hammerman and not much could have been discussed / diagnosed in so short a time. Secondly, her office had emailed me a rather lengthy form to fill out and submit before her appointment and therein I specifically stated that she did NOT want to take any pills prescribed ( I had read about the side effects of some of the acne meds and decided that creams/ ointments should be prescribed, at least initially. As far as her bedside manner, perhaps she woke up on the wrong side of her's this AM but she was quite unfriendly and standoffish -- quite a difference from the persona shown in her video. And lastly, my daughter had wanted some moles removed and when my daughter was finished seeing her, I asked the doctor about this. She replied that she didn't do laser mole removal and thst she'd have to see a plastic surgeon..But why didn't she recommend the doctor who was in her practice and whose brochure I had seen in her waiting room?! For the above reasons, neither I nor my 2 friends who were ready to see the doctor upon hearing my recommendation, will never see dr. hammerman..
She is very nice and professional . Her staff is also nice and accommodating .
She is awesome ????
The doctor was great and would recommend her to my friends!! The company's billing department was rude and didn't contact me back timely when they charged me twice. I got so fed up I decided to pay and never go back.
Dr. Hammerman took less than 10 min to examine me. She offered me some cream samples, barely looked at my skin, advised to come back in a few weeks. Even she removed a wart I asked her about I wasn't satisfied with this visit as I came for annual screening and wish to be examined more thorough. The staff was nice.
Excellent!! Great staff. Beautiful office. No waiting. Dr. Hammerman was thorough and professional. I have already recommended her to friends.
I love Dr. Hammerman. I've been seeing her for alopecia every month, and she's been nothing but sweet and accommodating. I highly recommend, as the office space is relaxed and clean, and her professionalism and genuine care for her patients shine through. Highly recommend!
Dr. Hammerman is very sincere, professional and understands the needs a patient requires and I would recommend Dr. Hammerman to anyone who needs skin care.
I have been to this office twice and have had the best experiences that I have ever had at any doctor's office. I waited less than 5 minutes both times, even though I was ten minutes early today. The doctor has excellent bedside manner and gives me all of the time that I need, even when I have a lot of questions. I even asked her if she had a good gynecologist that she would recommend in the area and she knew of a good one, even though she's a dermatologist. I love that she has evening hours so I don't have to miss work. I have only excellent feedback. Great experience.
She might be a good doctor and gave one good advice but it wasn't for the reason I went for. She wasn't sure about my issue whether it was a ring worm or not and said to apply a cream and see if it helps. What is the point of going to a doctor if they can't diagnose properly. And for me it matters if doctor is friendly which she didn't seem to be.
She was amazing!! She is very knowledgeable and pleasant. She did a thorough skin exam whilst keeping me posted as she conducted the examination. I was her first appointment so there was no wait time. I have found my dermatologist!!
Everything from the wait to the consult went well. What did NOT go well was arriving at the pharmacy over an hour after I left the office to find out she had not sent the prescription yet. Disappointing but other than that a great, fast visit.
Had a great first visit with Dr. Hammerman. She does a superb job with injecting Botox without it being overdone - she will just administer the minimum amount you need. She also gives very helpful suggestions on skin conditions such as rosacea. The office is clean and nice and I didn't have any wait. Overall, an excellent experience.
Very professional. Was the first appt so didn't have to wait.
Dr. Hammerman was very efficient and she had impeccable bed side manner. Extremely informative and very bright.
Dr. Hammerman was very professional and even took me early in the morning. I would recommend to anyone looking for an annual body scan.
Very professional and explained things well and thoroughly
Excellent doctor, strong knowledge and answers to questions in details. Recommend her to anyone
Very polite, professional, relaxed doctor who addressed all of my concerns. Her PA is also very nice.

I think it was great!
Dr. Hammerman was most knowledgeable, professional, and had a very nice manner as well. I highly recommend her!!
Excellent doctor, courteous would recommend her anytime.
It was ok. Just needed a prescription refill. Dr. Hammerman seems nice enough, I guess (I saw her for only a few minutes so I can't really say) but I really miss Dr. Azfar. Dr. Azfar was one of my favorite doctors, definitely in my top three ever.
