Verified Patient Reviews
She's my favorite dentist in NYC.
Doctor Rimma was excellent and very informative! Highly recommend
Everyone at the office was friendly and helpful. I'm really happy that I found this practice!
Very atentative and kind.
Everyone - from front desk staff to hygienists to dentist - at this office is lovely and they always keep things running right on time. I'd definitely recommend them!
I don't usually write recommendations beyond the star rating, but I had a really great experience on my first visit with Dr Portman. The office was bright, clean and the staff was really friendly. They took me in right at the scheduled time, Dr Portman was bright, energetic and friendly. I felt at ease with her, and she took the time to explain things to me. I look forward to continuing in her practice for years to come!!
Very friendly, great office.
I was 4 months overdue for a cleaning and so looking forward to get my teeth cleaned. I was disappointed. It felt like the hygienist was rushed cleaning my teeth, and afterwards my teeth still felt gritty. When the dentist arrived, we interacted overall for maybe 2 minutes total; the interaction felt rushed and a bit curt when I tried discussing a few things further. I will probably be going to a different dentist next time.
Always a great experience. Both Williamsburg and Park slope location. Staff is friendly and Doc is attentive to details. Equally important is truthful about what you need and don't need. Locations are clean and santinary as it should be. Updated technology too.
If you need anything other than a straightforward cleaning or filling, go someplace else. The hygienist and Dr. Portman both lacked a professional bedside manner and asked invasive, quizzical questions about my medical history seemingly more out of curiosity rather than real medical concern. They were not able to answer my questions on how my oral heath may be inductive of overall physical health and left me feeling like a circus side show with more questions than answers.
Best dentist around, great hygienist and staff!
Dr. Portman is beyond exceptional! My visit with her was professional, effective, efficient and the happiest I have ever been after any dentist visit in the past.
Had an excellent visit here for a teeth cleaning and preventative check-up. The receptionist was attentive and friendly, the dental hygienist was very thorough, and the dentist didn't have to do much but gave a nice amount of information and analysis. I'd highly recommend.
Dr. Portman is absolutely amazing and the staff is wonderful.
Dr. Portman is the best. Full stop. She is concerned, professional and technically super competent. Doesn't want to rush into unnecessary procedures. Can't recommend enough.
I love Dr. Portman. I've been going to her for a few years now. She is friendly, informal and quick. She works quickly and painlessly. I highly recommend seeing her.
She was great. Felt extremely comfortable. All of my friends go here. Great place!
Excellent Dentist. This is my third time visiting her. I didn't have to wait, the staff was very nice and the doctor is amazing. I highly recommend this dentist.
Second time coming for a cleaning. The staff I extremely friendly and Dr. Portman saw me within minutes of walking in the door. I recommend Dr. Portman and this office to everyone.
Dr. Portman and her team were very friendly and professional. As a new patient, I was fully registered and had my bi-annual cleaning completed under an hour. Would highly recommend Dr. Portman and her team!
Everyone was super kind and gave me a lot of information. Answered all my questions. Very comfortable experience. They work really hard with your insurance to make sure you're not going broke from procedures. Filled my forms online and when I showed up everything was ready. I just had to sign the papers and I was all set. Highly recommend!! Going back for follow up.
Made my first cavity filling a breeze!
Everyone in the office was super nice and welcoming. The doctor was very helpful and took the time to explain various options.
Wonderful office! The man at the front desk was super helpful and patient after my insurance information didn't go through ZocDoc (the paperwork I filled out online didn't make it to them...) and I didn't have my insurance card with me so he had to call my dental insurance to get my plan info. The hygienist Olga was wonderful and I felt like she did a thorough job with minimal discomfort. Dr. Portman was very friendly, efficient, and told me that I had some cavities possibly forming but that we would watch them (a previous practice told me I needed 7 filled at once which made me feel like they just wanted my $$... thank goodness I didn't listen). I will be back!
Great! Hygienist was lovely, thorough with my cleaning, professional and kind. Very little wait to see the doctor. Everyone was open to answering any questions from reception to the doctor. Will be my main office from now on!
The doctors are great, internal communication is excellent, always felt like I was in good hands...the entire staff is terrific. I highly recommend this practice.
Awesome sauce...love the doc, she's the best..Won't be going anywhere else ...
Started my veneer process. It was painless and Dr. Portman and her assistant were awesomeness. I will always be a client.
Dr. Portman was great!
The best dentist experience I have ever had. Couldn't possibly recommend any higher.
Rimma Portman ,DDS was great. Virtually no wait time. Receptionist extremely helpful from appointments to insurance, Mendy was excellent and professional made a new patient feel right at home. Portman as kind,gentle answered all my questions made me feel very comfortable and informed. Outstanding service. Will highly recommend.
Helpful, friendly and thorough! A really pleasant visit after being away from the dentist for far longer than I'd like to admit.
Very clean and professional office. Everyone was very nice and helpful. I was seen right away. I would highly recommend.
Thank Rimma! Everyone was so nice at your office :)
Very professional and efficient appointment. Really glad I chose Dr. Portman!
I can't say enough about how great my experience was. Dr. Portman was kind, succinct, extremely professional, and very skilled at her craft. She clearly explained to me what she was doing, and my options for additional dental work in the future. The care she showed was very personalized and made me feel comfortable with the decision I made. I would recommend all of my friends and family to see her and her staff for any work: cavity filling, cleaning, whitening, etc..
The entire staff was friendly and made me feel very comfortable. Dr. Rumna Portman was incredible. She took all my fear away about going to the dentist. She explained to me what was going to Happen and also performed the smoothest cleaning ever. I will coming back in 3 weeks to do my next cleaning and she will also be doing my veneers.
Great dentist! One of the best I have been to in the last few years. Dr. Portman has never been behind schedule, is always in a great mood, educates me well and gives great advice. I would recommend her to anyone looking for an outstanding dentist!
I love this whole office. All of the staff at Ismile are so welcoming...they were the sweetest to my 16 month-old while I had my cleaning. The equipment is new, receptionists are amazing and I am sad I hadn't found Rimma Portman sooner!
My first office visit was definitely a positive one. The office seemed clean & professional. All staff were friendly & polite. They did a thorough cleaning and check-up. Dr. Portman seemed polite & focused. I look forward to seeing what they can do with my repairs scheduled and having my work done there in the future.
The front desk staff, hygienists and Dr. Portman were all really friendly, professional and willing to answer questions.
I had a great experience - my appointment was quick and easy. I was told I had "cute teeth" which made me laugh. Dr. Portman will definitely become my go-to dentist in New York.
She was amazing! Super friendly and obviously knowledgeable, but really Dr. Portman separated herself form every other dentist I've ever had by the way in which she helped me feel at ease. I have a lot of work to do, having neglected my teeth for quite some time, yet Dr. Portman proverbially held my hand and made me feel good about starting my journey of tooth repair. I highly, highly recommend Dr. Portman and her staff!
Union Street location brand new and kept extremely clean. Wonderful service by all staff, starting from doctor Portman to the nurse and receptionist.
I hadn't been to a dentist in two years due to my fear of dental work. Dr Portman made it easy. The hygienist, Maria, was the absolute best I ever had. She knew how nervous I was and was so understanding and yet got my teeth so clean!! Thank you!!!
This will now be my regular dentist! Going to the dentist is usually traumatic which is why i take so long to go. Everyone at this office is wonderful from the front desk to the dental assistants. As for Dr. Portman her bedside manner is excellent, very personable but knows her stuff. Never had a dentist show and explain exactly what's wrong with my teeth with such detail without freaking me out. Highly recommend her!
Like many people I turn into my 12 year old self when I have to go visit the dentist. I'm pretty much on the verge of tears every time. Dr Portman is AMAZING. She made me feel super comfortable and didn't diminish my irrational fear. Highly Highly recommend her!
Saw Dr. Portman for the first time and was very impressed. She was professional, kind, encouraging, and informative.
Another fantastic appointment with Dr. Portman! I'm so thankful that I found a dentist that I'm not afraid to go to.
Dr. Portman is amazing and everyone who works for ismile has been lovely. I've visited both locations and they have never disappointed..
She was great. The staff was great. The office was great. Everything was great!
Dr. Portman's bedside manner was so stellar. I hadn't been to the dentist in quite a long time and both she and the dental assistant were understanding and very patient with me. The front desk staff were equally friendly and I was seen the moment I signed the necessary documents with the front desk.
I love her. Highly recommend.
Was dreading the visit to the dentist.. Rimma made it stress free and pain free!
Such a pleasant experience here! Everything was super fast and efficient, and I walked out feeling very knowledgeable about any issues that came up. Would definitely return!
Wonderful experience! Dr. Portman and her staff were attentive, thorough and made the entire experience great. Dr. Portman saw me right away and had awesome bedside manner. I will definitely recommend this office to friends and family.
Dr Portman is friendly, talented, and empathetic. The best experience at a dentist I've had by a lot. Quite pleasant, in fact!
Very thorough cleaning, awesome as usual.
The staff and Rimma are always pleasant. Nice office, easy location, good equipment. Everyone makes you feel comfortable.
She was extremely knowledgeable, helpful, and kind.
Excellent, timely care. Highly recommended.
Amazing knowledge and very helpful. Took time to listen to all my concerns and addressed them all in very understandable manner. Always looked for the best options! Just great, I would recommend her to everyone!
She and her staff are pleasant and helpful. I was seen within a few minutes of my appointment and everyone was very thorough.
Good experience - hard to judge from just one visit, but seems knowledgeable and professional.
This is my second visit to see Dr Portman and I was taken at my appmt time each time. Both the dental assistants that attended to me with xrays/pre-cleaning stuff were super friendly and nice. The girl at the front desk is also very nice. Dr Portman is awesome! I even made my boyfriend start going to her because she is so skilled and smart and makes you feel at ease for being at the dentist. I like that they have TV's in the exam rooms and the waiting area-keeps you distracted from thinking of why you're there. Highly recommend! Bonus that she takes Saturday appmts.
Dr. Portman and the staff at iSmile were very welcoming and professional. I visited the office for a cleaning and check-up, both of which went smoothly. I then had a few x-rays taken, had a brief discussion with Dr. Portman, and was on my way. Overall, a great visit. The office is very clean and modern. I'll be back in 6 months.
Great as always. Everyone is always nice and makes it a pleasurable experience.
my 2 year old daughter had no tear either pain with Dr Rimma. highly recommend her to anyone!!
She's the best. I actually like going to my dentist.
Friendly, answered all questions and did not try and sell me on invisiline!
Best dentist ever!
Rimma's great! Her and her staff are awesome!
Great hygienists always! Yesterday was no exception - shout out to Olga! Sr. Portman is great too!
Love Rimma and iSmile! Her office is super efficient, clean and calming. She gets you in and out quickly and the dental hygienists rock. I was afraid to get my first filling but they walked me through every detail and made the process super quick and painless.
I filled out paper work because it was my first visit, but otherwise I wasn't waiting at all. The room I had my teeth cleaned had a tv playing a nature documentary about pacific salmon and grizzly bears. During the cleaning I kept thinking that the basic survival of animals is so simple and refined. Grizzly bears never worry about appointments and they have great teeth for catching jumping salmon. On the other hand, pacific salmon die once they finish mating and the eggs gain nutrition from the rotting corpses of their ancestors. So...5 bags of popcorn and one bear with floss hanging out of its mouth.
Everyone working there was very kind and attentive. I, admittedly, had not been to the dentist in years and no one was shaming or judgemental, but instead taught me better oral health care and made me not hate the idea of regularly seeing a dentist.
Dr. Portman is great! Super nice, professional, and the staff is great too. Can't wait for my next cleaning!!
She's so nice and very efficient! Actually look forward to going to the dentist now :)
Highly recommended. She is very nice and professional.
She is awesome. Truthful and honest in terms of what needs to get done. Went to 4 high rated doctors across NYC for treatment plan and I chose her. Professionalism and staff are great. Explained exactly what was getting done including description of dental code of what it is compared to others. Only top of the line stuff at the reasonable competitive price. Thank you so much! Worth driving 40 min or more.
Excellent dental office, staff and hygienist friendly, professional and efficient. Dr. Portman is fantastic. Highly recommend!
I love that they have weekend appointments for those of us with strict schedules.
Even after my insurance, I seemed to pay more than I ever had at my previous dentist for cavity/annual appointment... not sure why? But, Doctor Portman and her staff are super nice... and the place is professional, clean, and modern.
I have been dreading going to the dentist, and this visit was way overdue. Dr Portman was extremely kind and did not judge, as most other dentists would have. The entire visit was very pleasant. I look forward to keeping up this routine every 6 months!
Excellent as always
It was great and was one of the best dental visits I have ever had. From the lady who cleaned my teeth to the dentist, all were very sweet to me and made me feel like they genuinely cared about my teeth. Definitely recommending it and shall be back! Thanks!
Dr Portman was a recommend to me, and so happy I started going to see her! The office is clean and modern. The staff and Dr are friendly. Dr Portman helped me fix a few issues I had developed (I hadn't been to the dentist in 8 years!) I was nervous about them, and she definitely kept me relaxed & made sure I was OK the entire time. I've been going back ever since for regular checkups!
Wonderful, clean, professional and accommodating. Highly recommended.
Very good dental hygienist as well as very professional dentist.
Really the best dental experience I ever had. Will never go elsewhere
She was approachable and patient.
She's the best. I've recommended her to friends. Always listens to concerns, and her solutions to my dental problems weren't always the expensive or complicated answers. She works with my budget.
She was very good, and her hygenist was terrific. My only complaint is the front desk staff, who were curt/terse and not paying attention to what they were doing. Additionally, they assured me follow-up same day on next steps for my procedure, but they have not followed-up. Perhaps they are just having a bad day, but I would not like to have that experience again.
Short, sweet and straightforward.
Did a cleaning and the assistant was very gentle, friendly and kind. Xray technology was fast, advanced and easy too.
Rimma Portman is honestly the only dentist I've ever had that's made me feel comfortable. The office is great and the staff/hygienists are so friendly!
I've been coming to her for a few years. The assistants are very bubbly and friendly. Rimma is lovely and bubbly as well. I never have to wait long. Facilities are very clean and modern. They are organised and utilise the zoc doc medical history so you don't have to refill everything out. The best!
My new dentist! Very laid-back and friendly team.
Dr. Rimma Portman is incredibly attentive, compassionate and charismatic. The process was painless, comfortable, and overall no hassle at all. She was up- front about my individual insurance costs for procedures, areas of concern, etc. Her staff was extremely friendly and attentive and the office is new and spotless. Thanks ZocDoc for helping me find my new dentist.
Very clean, orderly, and professional office!
I was super nervous but everyone in the office made my visit pleasant
Not recommending for crown.
I would highly recommend. Great experience, short wait time, very professional and knowledgeable. Rimma took her time to answer all questions thoroughly. Clean and modern office.
She is very kind and takes the time to explain the treatment carefully. She also does her best to respect the fact that I'm a tooth pain woosie
Everyone was professional and friendly.
I hadn't been to the dentist in over 4 years, so I was really nervous. The office was clean and I was greeted warmly, so that put me at ease. I was brought in right away (after filling out my paperwork) and was taken care of by a very nice dental assistant, who did a great job talking to me, checking in to make sure everything was okay, etc. Turns out, no cavities! So I left very happy. Will definitely be back in 6 months.
Let me pick the cavity filling toonz
I didn't got to the dentist for quite some time, and I am glad I did. Dr. Portman found a few things that need to be addressed, and I am looking forward to coming back and getting it taken care of! Very friendly office, and exceptionally professional.
Best dentist ever!
Dr. Portman and her staff were both professional and personable. It was all-around a very pleasant experience.
Everyone was very professional and very pleasant. High quality service.
Excellent practice, friendly and caring. I look forward to my next visit.
Best dental experience I've ever had.
Friendly staff, great dentist! Highly recommend!! :-)
Wonderful dentist. She and all her staff were extremely professional and helpful. Highly recommended.
she was really cool! Definitely a sweet lady found my new dentist!
It was a very pleasent experience as far as dental visits go! I was greeted by a very polite and smiling reception person who quickly sorted out the cheking in process and offered a cup of tea or water while I wiated. It took a few minutes to sort of the insurance issues, but that was basically my own fault for forgetting my card. They handeled it smoothly and the apoinment went on very well to include a thourough checkup, x-rays and cleaning. The communication and explanations and advice were great and I felt being taken seriously and given good recommendations. In the end Dr. Portman reccomended that I should see an oral surgeon to make sure my wisdom tooth could be removed without any danger of infections. A good reccommendation to make sure everything would be handled in the best way. I was happy with the visit and would happily reccomed Dr. Portman and the iSmile clinic.
She is amazing because when she sees you she is very polite and her attitude is very welcoming. When she is working on your teeth she explains everything she is doing while it's being done. I feel so comfortable and I love the work so far.
I love it.
Best dentist visit ever - the hygienist is awesome and Dr. Portman made me feel great about my teeth, I will definitely be back!
Natalie was great as was her staff. They did a great job cleaning my teeth and were great with helping me understand my insurance!
Attentive. Great service. Friendly and accommodating front office as well
The little things can make all the difference in the world. My visit at Dr. Portman's was brimming with positive little things: everybody I interacted with had a smile; I was offered a cup of tea while I sat in the waiting room; the tooth polish used was the good tasting kind and not the gross chalky pasty stuff. It is almost as if this dentist office is on a valiant mission to combat that old stereotype about dentist appointments being unpleasant. If so, I think it is safe to say that they are succeeding.
Great bedside manner, easy to get an appointment!
Dr. Portman and her staff were great yet again. I have referred all of my friends to her office.
Extremely professional staff. Very nice and comforting. Would definitely recommend and come back.
Really enjoyed chatting with Dr Portman, her hygenist, and the guy who greeted me at the front desk. Thorough cleaning and clean, comfortable office in my neighborhood. Will be back!
Very professional and an outstanding Dentist. The staff is accommodating and equally professional. The receptionist are very helpful and always displays the best customer service. The facility is very clean, and they always adhere to the appointments schedule - no wait, no over booking. The emphasis is Quality over quantity.
Best Dentist experience I have had and Dr Rimma Portman is great at making you feel at ease.
Wonderful dentist. She and all her stuff were super nice and helpful. Highly recommended.
great dentist and very thorough technician - great visit!
Nice, clean, knowledgeable
Not a big fan of the dentist chair but Dr. Portman was super nice, conducted a thorough & pain-free check up / cleaning and will definitely be back there in 6 months.
I was in a lot of pain and found a Saturday appointment which was amazing. The office was nice, they have TV's in every room so you can't be overwhelmingly bored or anxious. Dr Portman was kind, thorough and answered all my questions. I think I will switch to her when my teeth cleaning is due!
Fantastic facility, staff, and care. I could not have asked for a better find in the area. Exemplary and highly rated!
I'm so glad I've found such a great dentist - I feel I can trust Dr Portman and she is also really friendly and puts me at ease in the dentist's chair. Level of service - can't fault it.
Really really liked her. I'm a nervous patient, and she put me very much at ease. I had a filling that fell out, and she fixed me right up. No pain at all- even the novocaine injection didn't hurt. Only complaint- it's a pretty expensive place if you're paying out of pocket. But I'm sure her rent is crazy in that location, so I get it.
Went in for a routine cleaning and it was super quick! Zero wait time, perfectly clean, modern office. Friendly and efficient staff. Dr. Portman even did the cleaning herself.
Everyone at the office was friendly. The office was clean and modern looking. I hadn't been to a dentist in about 8 years so I was very nervous - I told the Dental Hygienist and Doctor, and they were both very warm.
Dr Portman is, quite simply, the best dentist I've ever encountered. She made my considerable need for dental work an (almost) pleasant experience. Thoughtful and considerate, Dr Portman was conservative in her work; exercising diligence and professional consideration, rather than simply refilling teeth and generating work like other dentists I've experienced. I really can't recommend her enough. A++.
Doctor and staff were extremely nice, personable and gentle. Beautiful, clean office.
Dr. Portman and her team make going to the dentist as much of a pleasure as that could be! The entire staff is genuinely friendly and helpful and the office is extremely clean and comfortable. Very happy to finally find a dentist I like!
Great office and great team-- everyone was very friendly and upbeat, and seemed to genuinely enjoy their work, their patients, and each other.
Dr. Portman is kind, friendly, knowledgeable, and gentle, and the same goes for her staff. Wonderful people and I will be returning soon for a follow-up and would recommend her to anyone. She's great!
Very impressed with how proffesional, efficient and kind everyone were at ismile. Thank you for a great experience.
Nothing but Awesome. Hate going to the dentist but now I actually am excited to get my teeth cleaned.
My gums bled a little during/after my cleaning.
Excellent dentist and hygienist!,
She is very nice & overall excellent professional.
Very skilled and professional
Dr. Portman is great--friendly, matter-of-fact, and great at explaining any issues. Her team is wonderful too--great at explaining what they're doing and totally happy to pause if anything hurts or is uncomfortable. I'm already looking forward to my next cleaning!
Great - will be going to her regularly! So glad I found her.
She was the most informative and best dentist I have ever been to. I appreciate her honesty and her expertise.
Excellent dentist, really nice to have an office and dentist this great in the neighborhood.
Staff is super nice, professional and charming. I had an excellent experience. Not to mention the environment is super friendly and clean. Hi-fives to everyone that works there.
By far the best medical professional I've encountered in my four years in New York City. Would highly recommend her to anyone.
She was very honest and kind. Will definitely come see her again.
She was amazing and very professional
Amazing! One of the best dentists I have ever been to
Excellent experience, really friendly staff.
Dr. Portman is wonderful. I've gone to her for both a routine cleaning and a chipped tooth in the last eight months. She is warm, friendly, and a pleasure to be around - which is extremely important to find in a dentist!
Friendly, professional and charming
This was my third or so visit to this office and it was perfect yet again. I was seen right away and Dr. Portman and her staff were nice, efficient, and attentive.
She is great and explains things very well. And her hygienist does an excellent cleaning and is very pleasant. Actually, the whole office atmosphere is relaxing, professional, clean and uplifting!
Excellent experience. She is knowledgeable and empathetic. Passionately cares about long-term dental health rather than just the job-at-hand. A true professional.
Wonderful experience. Timely friendly and straightforward
Excellent experience all around!
Everyone who works in the office is lovely. They make you feel very welcome and comfortable from the moment you step inside. Dr. Portman is great, she knows exactly what she is doing and does so in a very kind and gentle manner. As a person who who dreads going to the dentist, I would highly recomend Dr. Portman's office.
Great! Was offered tea when I got there, and they gave me a hoodie bag of dental hygiene tools when I left.
Dr. Rimma Portman was wonderful, she is definitely my new dentist, professional, knowledgeable, and very kind. So glad I made an appointment with her!
I truly believe that i fell into the right hands as far as my dental care issues and that they are being resolved right away. The commute was just there, did not have a problem looking for the office. Now I have a better reason on taking care of my dental hygiene before didn't pay much mind. Thank you Dr.Portman.
I loved my visit with Dr Portman. I will definitely be going back as well as referring all my friends in the neighborhood. Everyone was so nice and made my experience really wonderful.
Great. All the team was friendly, professional and made the experience as good as it could possibly have been. And no guilt trips!
She was absolutely amazing and helpful. It was my first visit in years and she made me feel very comfortable. I'm looking forward to future visits with her!
Very Professional, and willing to answer questions. Her office was clean and welcoming. Her fellow co workers are also very personable and treat you with a genuine smile. Rimma is a very GENTLE Dentist. I was very weary of Dentists because they tend to be rough. She changed that completely. Cant be grateful enough. Highly recommended. Thanks!
This office is amazing! The reception staff is friendly and personable. The dental assistant was very warm. Dr. Portman is the best! Amazing bedside manner and she knows my fiance and I by first name. We love that!
Super nice. I had a teeth cleaning and whitening and am very satisfied with both. So glad I found her on zocdoc. She'll be my new go-to dentist
Very convenient location for me...I'm glad to have found Dr. Portman. She is easy to talk to and doesn't recommend unneeded work. She also goes out of her way to make you comfortable during your visit and I appreciate that a great deal.
She was amazing. Very gentle and thorough, explaining everything and making sure you are at ease. Wait time under 10 min each time I have been.
Friendly and professional. Easy to talk to. Staff was welcoming and dental hygienist was super sweet and thorough.
I went to see Dr. Rimma Portman for a sanity check about a tooth. I was able to schedule an appointment the day before and seen quickly. Although my yearly insurance limit was reached, she worked with me to ease my worries at a decent price. The office atmosphere was great and the staff is extremely welcoming. Went again for a checkup, and no changes to my earlier statements. If you are looking for a new dentist and live in the Williamsburg/Greenpoint area, there is no better choice. If you dont live in the area, it will be worth the trip :)
Very nice - she made me feel very comfortable
Great staff, everyone is super friendly. Dr. Portman is very nice and straight forward with answers. She spent a good amount of time with me and was extremely professional.
Dr Portman was kind, gentle, and so efficient! I was in the chair for a checkup, x-rays and a cleaning for less than 30 minutes. A+++
Very informative. Good bed side manner. Through.
The visit went smoothly, even though I have cavities. The dentist spent almost the whole appointment with me - I expected mostly the hygentist with a short visit from the doctor at the end. Also, everyone was really nice, and the exam chair has a light massage function for an extra bonus.
She was wonderful. Very attentive and concerned about my general well-being. I feel very safe with her and her dental team.
Really nice staff and professional.
Quick service, was in and out in under an hour. was seen by the dentist right away and she did my cleaning right after some x-rays.
Very friendly staff, very clean and professional office. Took me right away. One of the quickest and easiest trips to the Dentist I've ever had. A+!
She was absolutely outstanding - best option in the neighborhood
Dr. Portman was great. We previously went to one of the other larger dentist offices 2 blocks away, which was a disaster - lots of up-selling, very commercial, lots of complexity and overhead. Going to Dr. Portman was a relief - it was quick and professional. I got cleaning and checkup down, and need to go back for a filling. She was practical and honest, and I developed great trust for her. Looking forward to going back to this practice on regular basis.
I was immediately greeted by Dr. Portman's friendly receptionist (Robert?) and offered a water. She saw me right after after I arrived and introduced herself to me before my x-rays and cleaning. Her staff was friendly and professional, as was Dr. Portman. Her office is also very nice and soothing. I highly recommend her.
Very welcoming and nice staff. Doctor's extremely nice. I would go back.
Dr. Portman might be the greatest dentist I've ever seen. Her beaming personality and extremely friendly demeanor made what many often dread to be something I now look forward to. Something I was particularly surprised by was that she did my cleaning herself personally. I'm used to a hygienist doing it but the fact that she goes out of her way to do it herself shows how much she cares. Plus, she tweeted back at me which I think is just terrific. I have nothing but positive things to say about Dr. Portman and cannot wait for my next visit!
The facility was top notch. Got a very good cleaning and Xrays. Was my first time at the dentist since moving to NY from Vancouver and it was very positive.
Cleaning was a bit rough this time.
Dr. Portman was really friendly and straightforward and did a quick, painless cleaning. Would definitely recommend her if you're in the market for a new dentist.
This was the best dental experience u have ever had. Dr. Portman was kind, helpful, and have me great advice on how to take care of my dental needs. Not to mention the receptionist was also very professional and friendly. Great service here!
Dr. Portman is fantastic and her staff is warm and helpful
By far the easiest, calmest dentist visit I have ever had. The reception desk and Dr herself were both extremely kind and helpful. Dr. Portman made me feel at ease even though going to the dentist is probably my least favorite thing to do, bar none. She was excellent, we were in and out.
Dr. Portman was friendly and professional. I enjoyed my visit and felt comfortable when I had a filling done. Her staff is also very friendly and helpful.
The visit was excellent. Dr. Portman is great, thorough and a true professional.
Great appointment. I felt she was very thorough and professional and understood my needs right away and helped me plan for them. Office staff was also top notch!
I had a bad past experience elsewhere, so this was my first time back to the dentist in 8 years. The front desk staff was friendly, informative and attentive, and got me in for my appointment right away. The hygienist was personable but professional and helped me relax. Dr. Portman was kind and patient, explained everything to me, and courteously answered even silly questions. She was attentive to my comfort throughout the appointment and did an excellent job. I can't say I look forward to my next dentist visit, but I will definitely be going back to Dr. Portman and her staff.
Dr Portman is relaxed, approachable and professional. She offers the opportunity to ask questions, is cautious (which is what I want in a Dentist) and I have confidence in her skills and opinions
My new dentist is ... Awesome. Rimma was professional, friendly, her surgery clean and her team friendly too. I have no hesitation in recommending her and their clinic in Williamsburg, Brooklyn NY.
Dr. Portman was so patient and friendly. I'm nervous around dentists and she was very attentive and made me feel like I was her only patient. The office is clean and the people are so nice. I actually enjoyed my visit.
Honestly, if I could give 6 stars I would.
I went in with a cosmetic concern and found that I had four cavities. I wasn't experiencing any pain before my visit. Dr Portman filled four of my teeth. Two of the fillings fell out after a few days, and I was refunded for the full amount. The third filling fell out around a month later, and my current dentist noted that the fourth has also started breaking down, so we are just anticipating that one to go soon too. I ended up paying much more than I would have since I had to put temporary fillings in for a month to calm the teeth before re-filling them. It was a painful process, basically filling each tooth three times, and my teeth have never felt the same. I don't know why this happened- maybe it was an issue with the actual filler material, or her technique. Either way I wouldn't recommend this dentist.
Very friendly, thorough, and knowledgable
Staff very friendly and professional. Will continue to use her as our family dentist. Highly recommended.
Dr. Portman and her staff are great. My visit went very smoothly.
Great! Don't like the dentist, but immediately recommended her to five people after my first visit.
I enjoyed my first appointment with Dr Portman. The dental office felt comfortable and inviting. Dr Portman was very pleasant and willing to take the time to talk thoroughly about my procedure. I'm planning to book another appointment.
I never thought a visit to the dentist could be a pleasurable experience...typically, I considered a "painless" trip a success. That is until I went to see Dr. Portman. I was welcomed to her office, escorted to my appointment immediately, and my cleaning was gentle and pain-free. I've already booked my follow-up appointment for next week!
Guy at front desk is incredibly nice and upbeat. Rimma has great bedside manner. Everything inside is clean, new, and nice. Only minor complaint is Rimma is a little short with her assistant. She gets exasperated easily around her which made me a little uncomfortable, but both her and her assistant were excellent, efficient, and nice.
Always a pleasure to visit Dr.Portman. I have recommended this office to everyone I know.
It's such a great feeling to find a doctor who is courteous, professional, and caring. Dr. Portman sat with me before and after the procedure, showing and explaining what needs to be done and how she would go about doing it. I was treated with utmost respect and dignity. In addition, the office was super clean and accommodating. As soon as I entered, I was offered bottled water and had an ipad to play with! Thank you Dr. Portman!
This visit was one of the most pleasant experiences I have had in a Doctor's office! The receptionist was so lovely and offered me tea as soon as I walked in. The office was comfortable and clean and I was seen right away. The Dentist was very friendly and good in her explanations. When I needed to have a filling redone, she first checked my insurance so she could let me know what the copay would be before the procedure. On the way out, they even offered me a bottle of water for the road! Great experience and highly recommended.
Everyone there is incredibly friendly. The place is immaculate and everything was done ridiculously fast. Was seen right on the dot and out in 1/2 hour. Immediately told my friend to book an appt if she takes his insurance.
5 Stars aren't enough!!! I'm ashamed to say but I've always had a fear of going to the dentist, I would avoid at all cost. That is until I found Dr. Portman. After neglecting my teeth for quite some time, I finally booked an appointment at iSmile (at a recommendation from a friend) for a consultation and a cleaning and I feel like a new person. Dr. Portman is sweet, friendly and educated. She took her time explaining the entire process to me. Her office is the nicest office I have been to, very clean, modern with flat screen tv's, ipads, just beautiful. The staff was excellent and friendly I will surely be back with my entire family. I can't say enough about how wonderful, gentle, thorough she was. She just had a way of making me feel at comfortable and at ease. HIGHLY RECOMMEND!!!
Best dental experience ever!!! The office is beautiful and modern, Dr. Portman was amazing and took her time answering all my questions. My visit was quick and painless. I will definitely be back.
Best dentist I've been to in a long time. Everyone was very warm and friendly. Dr. Portman was very professional and kind.
Was very pushy about procedures that weren't necessary. Wasn't reassuring or offer good explanations as to why.
It had been years since I'd been to the dentist, and I needed to find a good one in Brooklyn. Also, more importantly, after years of not taking care of my teeth, I had some serious gumline cavities that I knew were very close to becoming root canals. Dr. Rimma was very pleasant and matter of fact. Needless to say, she was slightly taken aback by the state of my mouth (though not rude about it, of course). She helped me identify all my cavities and we worked out how many visits it would take to fill them all. Most importantly, she was very reasonable about the prospect of a root canal, assuring me that it wouldn't be the end of the world, but that it's obviously a procedure we wouldn't want to rush into. I had been a little worried about the cost of having so many cavities filled and even more worried that an unscrupulous dentist might try to rush me into an expensive procedure. Dr. Rimma did the opposite: explaining the ways that she was preventing the decay from reaching that point. When she did fill them, she was very sensitive to any possible discomfort, obviously took a lot of care, and ultimately did a fantastic job. What could be obvious fillings on the front of my teeth are completely invisible! At the counter, the receptionist was very friendly and helpful. I was in the middle of switching from one insurance plan to another, and so figuring out my coverage took a few phone calls. The receptionist did the research gladly, and assured me that we'd get it all sorted out. When a filling was expensive, he offered payment plans. We also had a few nice chats--a very pleasant, interesting guy! As far as facilities: they were very nice and modern and the practice conveniently located close to the Bedford L. So basically, I think I've put this practice to the test, and I'd give them 10/10 in every aspect. Highly recommended.
Dr. Portman was very friendly and professional. She was very clear regarding the treatment plan. Her hygienist and office staff were friendly and professional as well. I plan continue visiting Dr. Portman in the future.
Best dental experience in my life!!!
A fabulous dentist with a fabulous staff. Everyone was so friendly and efficient. I would recommend her to anyone.
Excellent customer service. Ms. Portman is a great specialist and it's always a pleasure to come for a visit.
She was so kind and patient when I had some insurance issues. Robert up front was equally as kind and patient and made me feel very welcome. Will definitely recommend to my friends. Happy to have found a dentist I won't mind going to!
The office is beautiful, and the staff is really nice! I will definitely go back. I had a 10/10 experience.
Rimma is the perfect dentist. To me what matter the most is that she has an excellent-amazing hand. I also loved that she designed a very "visible and palpable" plan to fix my teeth and re-fix what other dentists have done wrong in the past -since honestly I just have a disaster on my back upper teeth that makes my whole mouth feel kind of acidic-. She already fixed 3 teeth -those I needed to get done urgently-, and still need to work in 2 more (One to fix, the other one to get re-done, and then, at the end, two implants). Big Pluses: the technology she used might be the latest in the market, and the interaction with her assistant is enjoyable. (Not only the dentist, they all are very professional there, kind and caring people). The office has a sort of fancy modern looking, that combined with their professionalism, honesty and kindness, helped me to be very relaxed the whole time. Just can't believe it -seriously, it was my only pleasant experience at any dentist. Excelsior dental job. It was worth my whole life search and those 30' drive I have to do in order to get there. Don't care, I have found my dentist with Rimma. Thanks for reading.
Excellent! She offered to check my insurance to make sure I wouldn't pay for the visit. Pleasant office staff who offered me a bottle on the way in. Definitely coming back.
My visit was great! Would recommend her to anyone. She's extremely welcoming, sweet, super cool and attentive. She super educated makes you feel very comfortable. Her office space is very clean and up to date technology makes it a plus! Not to forget the amazing front desk man who offered me got green tea and water!
Convenient, fast and knowledgeable. Will return.
Most relaxing dental appointment I've ever had -- a small, bright, clean office in a new building, with a fantastic staff. I watched TV during my cleaning, minimal discomfort. Dr Portman was very considerate and careful.
Dr. Portman was great- very nice and informative. Also very good about looking into what my insurance would cover in advance. This was probably my most pleasant visit to the dentist so far.
Dr. Portman is awesome and my appointment was quick, easy, and as comfortable as I could hope for. I'd recommend her to anyone!
I pretty much hated the dentist until I've found Dr. Portman. She really knows what she is doing and is extremely gentle. A very inviting office environment and friendly staff as well.
