Check out what some of our happy patients are saying about us:

Karen G. from Manhattan, NY (Source: Yelp)


We did several ortho consults before finding Dr. Grinbaum. I am so glad we did! She is incredibly professional, attentive, explains everything. Both of my daughters are happy to go see her, even the one who is usually jittery in the dentist chair. Her team is prompt, efficient and incredibly warm and patient. She also happened to be reasonably priced, especially given the convenient location.

I had crooked teeth and over bite issues. I looked up Dr. Karin Grinbaum on google and visited her. She was very warm, friendly, knowledgable and helpful. She suggested me Incognito braces for my case and I took coupla weeks to think it over and went back to her and got them. I read online reviews on incognito and a lot of people said it was extremely painful that they had to get them off. Dr. Grinbaum warned me there would be some pain and it will take few weeks to get adjusted and accustomed to them. Honestly it wasn’t very painful. Yes, it took sometime to get adjusted but it was never unbearable. Anytime I had issues with the wires poking or anything, I could get an appointment immediately and Dr. had adjusted them. Her warm & friendly smile took my fear away and I hardly felt any pain. She was there anytime I needed any help. Once I ate chestnuts and broke a brace and I immediately got an appointment and got it fixed. I got my braces off couple of months ago and my teeth are perfect, my smile looks great. Their office is very clean, staff are very friendly and courteous, Dr. Grinbaum is very sweet and knowledgable. Her assistant Julia is very nice too. And I loved Shannon at the front desk who is not working there anymore. The new lady at the front desk, Stephanie is super nice too. If you are looking for a good dentist who can perfect your teeth, I strongly suggest Dr. Karin Grinbaum. Five stars to her.

Dr. Karin Grinbaum and her team showed such knowledge and care in determining my teeth aligning needs. Once I received the aligners, they helped me set them up and try them on and guided me how to use them properly going forward once. They also offer a checkup every few weeks to determine progress. They make the process seamless. Highly recommend. Thank you!

I’ve been wanting to get Invisalign for a while now but I couldn’t find the right dentist that I felt comfortable with, until I met Dr. Grinbaum.  She is so nice and extremely knowledgeable.  She was very thorough in examining my teeth and took her time to answer all my questions.  I’m so happy with the results and my teeth look great now thanx to Dr. Grinbaum.

Dr. Grinbaum and her staff of professionals take “amazing” to the next level! They expertly installed my lingual braces in January. Within weeks I saw massive improvement! They’re always polite, professional, friendly, and happy each visit. They truly make it a fantastic journey to your best smile. Highly Recommended!! 5☆ Sincerely, Michael Carey

Nataly S. from Manhattan, NY (Source: Yelp)


I recently visited the office for an invisalign consultation. I must say I was beyond impressed. The office is beautiful and Dr Grinbaum was very knowledgeable and friendly. I have been to a few other consultations and the pricing was much higher and the orthodontists were not as friendly or helpful in making a decision. We discussed the benefits of Invisalign vs another option called Internal Lingual Braces. This is something that no other Orthodontist had even offered to me in any of my visits. I decided on invasalign based on the work I needed but both options seem like the perfect solution for anyone considering braces at a later age. I highly reccomend a visit to this office.

Ben C. from Upper West Side, Manhattan, NY (Source: Yelp)


I’m not a “yelper” but this one worth it. I heard about Dr. Karin Grinbaum through my dentist. All my life I had crowded teeth, never smiled in pics, very insecure about them. I did my research and Dr. Grinbaum was my second opinion. I’ve met her for a FREE consultation and immediately I fell in love. She was patient, informative, and so gentle. She gave me 3 options (other places only gave me 1 option) and explained the process, the costs and the end result. Even was straight and honest when I asked for her personal opinion. Front desk provided me with 3 different super easy payment plans. In a month a half I had the newest braces on. They were in the back of my teeth. I work in the service industry and I talk a lot to client so I didn’t want them to notice. Throughout the process I went to visit once every 4-6 weeks. I met KELLY and she is so incredible as well. Every question or concern that I had during the process the whole place was right by my side to guide me and to assist me. In only 10 months I have straight teeth. Dr. Grinbaum took such a good care of me! She gave me permanent retainers and a regular once as well. IM SO HAPPY WITH THE RESULTS! ! ! I have confident, my work is better, my smile is better and I’m so grateful for every little thing they did for me.

Always a professional and friendly staff and office. Really great particularly with children. Dr. G. has been amazing with my 10-11 year old during her treatment. My daughter feels so comfortable and Dr. G and staff have been helpful and available via phone and email throughout. I’ve been so impressed with the quality of work that I am now starting treatment of my own.

I’m amazed by the level of service from everyone at this office. Dr. Grinbaum is phenomenal! They make sure to explain every step of the process. I highly recommend!! My friends went to Dr. Karin Grinbaum after my recommendation, and all have great feedback. I myself was referred by two close friends that were treated by her, I believe that says it all.

Maria L. from New York, NY (Source: Yelp)


I recently completed Incognito treatment, which is a big commitment, but I am so glad that I chose Dr. Grinbaum for this. She explained everything up front so I knew what to expect. She and her staff were always available if I had a question or an issue during the treatment. It took about 9 months for me to complete Incognito, and it was very tough at times, but the results are fantastic. You can’t beat this doctor.

Lana T. from Honolulu, HI (Source: Yelp)


I am amazed and impressed with the staff at Grinbaum’s office. I was desperately trying to find a suitable orthodontist last year because I stupidly ordered smile direct club and my smile did not improve one bit. The initial consultation was quick and informative. Being able to pay monthly really helped me and that is what I really needed. The cost is affordable and reasonable and the customer service is awesome! I never had braces when I was younger because I was told I had to break my jaw to fix my cross bite/under bite.  Dr.Grinbaum only had one tooth removed and moved my teeth so quickly. After a few months, I no longer had an underbite. I ended up moving to California in the middle of my treatment, but did not want to change orthodontists. My treatment was done in FOURTEEN months. I am baffled and so happy. They really worked with me to get things done fast since I always fly in every 6-8 weeks. The staff and Dr.Grinbaum are the best. I highly recommend

Dr. Grinbaum is one of the best! I began treatment at her practice almost one year ago. My orthodontic situation was a bit complicated..I had a severely shifted midline I never thought could be repaired. I met with Dr. Grinbaum and she spoke very honestly and relayed several options for treatment. I decided to follow through with her practice and have never been more happy. She is highly conscientious, meticulous, and caring. She is genuinely there to help and full-fill any commitments. My entire experience with her and all her staff has been purely pleasurable. The results are everything I could have hoped/imagined. Grinbaum Orthodontics comes highly recommended!

Sarah D. from Manhattan, NY (Source: Yelp)


Dr. Grinbaum immediately made me feel at ease when I sat in her chair. Moving from LA, New York dentists were scarier than most other explorations. She was informed, gentle, and efficient. I have incognito braces and am over the moon that no one knows that they are in place. In only three months I already have noticed a significant difference. I strongly urge any patient seeking straighter teeth to solicit Dr. Grinbaum’s services.

Shannon M. from Brooklyn, NY (Source: Yelp)


Fantastic! Everyone is so nice in the office–Dr. Grinbaum’s secretary was very kind to me even though I was a few minutes late because of train delays. Dr. Grinbaum was friendly and answered all of my questions. I’ve just moved away from my main orthodontist in Buffalo, and Dr. Grinbaum was kind enough to tighten my retainer and give me plenty of retainer cleaner. She is very kind, personable, and gave me all the info I needed. Definitely will go back if anything goes wrong with my retainers in the future!

Pat R. from White Plains, NY (Source: Yelp)


Having braces in my later years was something I found appealing. I went for several opinions. One doctor wanted to pull some teeth- including a canine tooth. I found out later that you should NEVER pull a canine. When I met Dr. Karin Grinbam I knew immediately she was the orthodontist for me. The office is state of the art and very relaxed. The staff is young and very professional yet personal. And Dr. Grinbaum put all my anxiety to rest. She is amazing! Very on target with what would be happening as time went on. She is ver relaxed and personable. I feel so comfortable with her. I highly recommend this practice. She is extremely honest and accommodating. I have a few months left with the braces, and I see a huge difference already. Dr. Grinbaum assures me my teeth will be perfect and I am confident they will be!!

I highly recommend this office, in fact I have already to 2 other co workers. I was referred here by a friend and I am extremely happy, I was in market for some time and I’m big on chemistry especially my doctors. I found the office pleasantly spacious, modern , almost like a spa setting. I had my initial consult back in September 2018 and learnt quickly that appointments go very quickly here so move fast. I appreciate the ability to communicate with office via email which is very convenient through out my work day. Cheryl has been a delight very helpful and thorough. I had my fitting for ceramic braces yesterday, Kiara was extremely pleasant and put me at ease. Dr. Grinbaun is efficient and very thorough from the initial consult to yesterday fitting. I appreciate this office and I am happy to be having them take of my smiles Sincerely Artie

Valerie G. from New York, NY (Source: Yelp)


I’m halfway through treatment and still in love with this practice. I absolutely selected the right professional to administer Invisalign treatment to correct an unruly bite that made it difficult to chew.  Dr. Grinbaum is whip smart, as is her teacher, an oral surgeon at Mt. Sinai I consulted with about my jaw, and her staff is friendly and extremely capable.  Dr. Grinbaum is insightful and intuitive, she has a magician’s ease with her medical skill. Her team take the time to explain everything in detail.  My treatment is completing sooner than I anticipated, my bite corrected very quickly, and I can chew with ease now.  She also surprised me by filing away some unruly edges and polishing my teeth.  My teeth look and feel like a million bucks, and she hasn’t even “tweaked” them yet.  This treatment has exceeded expectations on all fronts.

Dr Grinbaum is very friendly, professional, and knowledgeable in her field. The staff is very nice and professional. The only complain I have is the appointments don’t usually start on time. I waited over an hour and another time 30 minutes after arriving on time for my appointments. These are business hours, we have work to go back to. Waiting for so long post appointment time is upsetting.

I’ve just completed my nearly 2 year treatment with Dr. Grinbaum and I’m extremely impressed with the results I’m seeing! She is very professional, yet personable. Actually, her entire team is simply fabulous! Always kind, efficient and accommodating and the office has a nice warm vibe to it. I would HIGHLY recommend!!

Amilia M. from Brooklyn, NY (Source: Yelp)


Dr. Karin Grinbaum is a great orthodontist. She is very professional and helped my younger sister with her braces. We first went to an orthodontist in Brooklyn but, my mother did not agree with his ideas towards my sisters braces because she need 4 TEETH to be extracted. So we went to Dr. Grinbaum and she told us that one, he put the braces on incorrectly and two, he was wrong towards his opinion and it would have made her lips droopy. So we got an appeal and continued the treatment with her. We all love her, she is very nice, professional very well informing and does her very best to help her patients. She is must see orthodontist!

Emily D. from New York, NY (Source: Yelp)


Dr Grinbaum is my orthodontist and I could not be happier with the treatment she is providing me. From the moment I stepped into her office I felt relaxed and she is so knowledgeable- I knew I was in good hands! Since I am not an adolescent getting braces for the first time I wanted more esthetic options to look age appropriate. Dr Grinbaum offers invisalign (clear aligners) and braces behind the teeth!! Who knew braces can go behind the teeth!! I had gone on two previous consultations and Dr Grinbaum was VERY reasonably priced compared to the other orthodontist. On top of that, her office was very clean and comfortable. I now am 3 months into treatment with braces behind my teeth and my teeth are noticeably better. I feel so much more confident because my teeth look so straight and no one knows I am wearing braces! Dr Grinbaum is the best! I would recommend her to anyone.

Dr. Grinbaum and her team (assistant and receptionist) are awesome. Efficient, considerate and caring. They always make you feel relaxed and comfortable. I have been with them for more than two years. Can’t recommend them more! They make doing braces a wonderful journey.

Dr. Grinbaum is the best orthodontist ever. she is more then an orthodontist, she is a friend. She is professional and so nice. She listens to her clients and does her acts. Her staff are as nice as her and work gently and friendly. They are the best!

Nathalie L. from Bronx, NY (Source: Yelp)


Dr. Grinbaum and her team are the absolute best. Im not a fan of going to the dentist or orthodontist but this team has changed that for me. Consultation was free of charged and was very thorough. Dr. Grinbaum and Kelly took their time to assess me and answer all my questions and was available any time if I had any follow up questions. Someone mentioned coming to the office is like visiting your friends and they’re so right! They don’t just assess you and dismiss you – they actually get to know you. I come in and I don’t even have to say my name because Carmen is just that good! I paid out of pocket for my incognito braces and they were flexible with the payment plan. I was only a few weeks into my treatment and immediately saw results – even my friends and colleagues mention it. There is no better dental office in the world that will compare to Dr. Grinbaum and everyone in her team. Cant wait to keep seeing results progress.

Dr. Grinbaum was excellent in solving the problem my son had with his hidden canine. He had ingrowing teeth, and they were crooked. She patiently listened and understood our concerns, explained the options and answered all our questions. The treatment lasted 4 years because of the complexity and the options we chose, she did an excellent job over that time. All his teeth were retained. She was very good at communicating with my son as well. Her assistant was very good and helpful. The rest of the office staff was very helpful as well. I highly recommend Dr. Grinbaum, she is very competent, and really good at her work.

The office is amazing! As a new patient they were so helpful on the phone and answered all my questions. Followed up with texts and calls to make sure I was all set for the appointment. The wait time was not long at all. The office is very nice & all the staff was friendly and helpful. The orthodontist was very thorough and had great energy. Definitely a different positive experience when thinking about medical offices.

Lital R. from New York, NY (Source: Yelp)


I was told by my dentist to consider braces so I started my search. I consulted with 4 orthodontists before I found Dr. Grinbaum, with whom I am doing lingual braces. She is the nicest, kindest doctor I have ever had! She is also extremely patience, honest and professional. Meet her once and you’ll be hooked!

Scott MacTavish (Source: Google)


Everyone was super friendly and professional – they’re clearly passionate about what they do and provide a great service. It was a bit sales focused at the end but as an ex-pat Brit living in the USA, I have started to get used to health and wellness being a commercial commodity rather than just a human-right. My UK doctor explained that UK medicine & dentistry is more reactive (and cheaper) and the US is more preventative (therefore more expensive)

Fitim Shabani (Source: Google)


THE ABSOLUTE BEST. —Dr. G and her staff are highly experienced in the work they do. They are meticulous and pay attention to every detail with every patient. The service is excellent and I’m always left feeling like I’m in good hands (no all-state joke) ha! HIGHLY HIGHLY recommend Dr. Grinbaum. I can’t wait to see my final results in the coming months

Jamie O. from Williamsburg - South Side, Brooklyn, NY (Source: Yelp)


This is the most amazing dental office. It’s such an amazing environment, and I actually enjoy coming for my appointments. Dr. Grinbaum did great work on my smile with incognito braces. Beyond that, everyone that works there is so fun, considerate and caring. Today, I showed up for my appointment with a severe migraine, and they actually were able to work on my teeth with dimmed lights and soft voices to accommodate my headache.

Samantha S. from Manhattan, NY (Source: Yelp)


This review is long overdue. I DO NOT KNOW WHERE TO START. I am actually IN LOVE AND OBSESSED WITH EVERYONE IN THIS OFFICE. I had braces as a teen but never wore my retainer so my teeth shifted back. I was really self conscious and didn’t want invisalign because taking them out to eat is kind of gross so I visited Dr. Grinbaum for a ceramic braces consult after going to several other different doctors. It was a no brainer once I stepped foot in her office. She sat me down and went over everything in depth with me and was soooooo nice and friendly and seemed extremely confident and smart which led me to stick with her. Not only if she so nice, comforting, sweet and experienced.. she’s also beautiful!!! I felt soo confident that I would be in the best of hands so I decided to make an appointment and get my braces on! Everything has been going to smoothly and I only have 10 more weeks left. I look forward to each appointment I have with Dr. Grinbaum and Kelly and the other wonderful people in the office because they’re so inviting and I leave happy. My teeth are almost 100% straight.. I cannot wait for the final 10 weeks I have left with these braces. She also is known for incognito braces so definitely consider those if you go into a consult. The best part is I will have a permanent retainer so I don’t have to worry about my teeth shifting back after. I’m SO thrilled I found Dr. Grinbaum but it wasn’t hard because I typed in “BEST ORTHODONTIST IN MANHATTAN” and she was on the list. She’s phenomenal and so is everyone in the office. I’m so happy. BEST DECISION I HAVE EVER MADE! I will write another review and post pictures of my smile when they are off. 10 OUT OF 10!!!

Had my first consultation with Dr. Grinbaum this week. Dr. Grinbaum and her staff were friendly, knowledgeable, and professional. I’m excited about the process and looking forward to the results. Dr. Grinbaum and her staff are pretty amazing. Highly recommended. Class act.

Erlinda Cota (Source: Google)


It is so hard with my schedule to make it to appointments and they were so flexible, extremely helpful and caring. I went there and had my free consultation for invisalign. Dr. Grinbaum was extremely kind and knowledgeable. She explained everything patiently without any pressure. She was extremely professional and kind. Same goes for the staff, everyone was AMAZING. There is really very few doctor’s offices in NYC you can get this caring service. I still haven’t decided if I’ll do invisalign now or later but whenever I’m ready this place will be my number 1 choice, and I’ll definitely recommend Dr. Grinbaum to every person I know! Wish I could give 10 stars!!!

If you’ve gone to orthodontic consultations and are frustrated by the doc-in-a-box mentality of prescribing an overpriced plan with no certainty of a better result, do not be discouraged — Grinbaum Orthodontics exists! I’ve been in touch with a lot of NYC orthodontists over the last month (about 40 in total), and Grinbaum Orthodontics has been a glowing winner…here’s why: Cheryl replied within 24 hours of my inquiry and scheduled my appointment quickly. The consultation was 100% complimentary and I was surprised as the majority of orthodontists charge big consultation fees ranging from $75 to $495. Due to train delays, I arrived a bit late so I called the office to see if I could reschedule and Cheryl reassured me that there was no problem and to come in. I was greeted by her bright, lovely smile that made me feel less nervous about my appointment. They works as a unit: Kiara was the first to discuss my motivations in getting orthodontic treatment. She was extremely attentive and so very kind, and I genuinely knew that she was hearing my concerns; she told me that Dr. Grinbaum is expertly trained in the lingual braces treatment that I’ve wanted for years now. I met Kelly who was such a sweet soul and extremely thorough in answering my many questions. She digitally scanned my teeth so Dr. Grinbaum could have another visual to consult during her examination. During this last month, many orthodontic offices boasted about their technology or awards in an effort to propel me into treatment asap. None of this happened; there was no pomp and circumstance, no showing me previous patient progress photos or name-dropping the projects they were involved with; I appreciated how focused everyone was on this specific case, on the result rather than the technology, and on explaining what will happen next for the sake of my comfort instead of trying to impress me into signing for treatment the same day. Dr. Grinbaum is beyond qualified with her many years of studies at NYU Dental and beyond, but humbly offered her professional opinion instead of overcompensating low quality practices with titles and accolades. Almost every doctor I visited in hopes of getting lingual braces (as listed on their site) told me that they no longer use them due to their complexity and cost, and instead highly favor Invisalign to get the same results as “obsolete” lingual braces. Speaking with Dr. Grinbaum, I quickly realized that it was not the expense or lack of demand for these discreet braces that led to their scarcity; it became apparent that many orthodontists either did not have enough experience with lingual braces or did not want the hassle of a long treatment time with their patient, and instead opted for Invisalign as a bandaid to the problem. I have not met a doctor in New York as comfortable administering treatment with lingual braces as Dr. Grinbaum. I have previously heard wild treatment plans offered to the tune of surgically implanted TAD expanders, shaving or pulling my teeth to make room, Invisalign with a post period of traditional braces for a few months that would not be covered under the initially quoted plan. I received better options from Dr. Grinbaum and her team, but lingual braces sounded the best to me as a working adult. Dr. Grinbaum sat down and discussed that lingual braces will alleviate the crowding, crossbite, & narrow palate with my compliance in approximately 20 mo. She did not offer any magical guarantees and was realistic in telling me that this is a huge commitment we will take on to get my teeth and bite as aligned as possible. She worked with Kelly to create a viable plan for my treatment, and was so genuine in alleviating my apprehensions. She sat with me for as long as needed and asked me a few times if there was anything else she may address or expand upon, instead of rushing me out of the office for another patient as so many have done before. Karin Grinbaum is a class act. I have read many reviews about her exceptional treatment of adolescent patients and I have no doubt that she makes her patients of all ages comfortable in her care. I also mentioned to Kelly that I have a few orthodontic consultations left before I make my decision and instead of taking offense to shopping around for this huge financial and time-consuming decision, she without a second thought asked when would be the right time to follow up. A few hours after the consultation, Kelly was extremely thoughtful and sent the plans we discussed with everything written eloquently and clearly (in comparison, I’ve had someone jot down numbers on a post-it note before ushering me out of the office). Orthodontic work is such a huge commitment and personal investment. I have a few more dreaded consultations to ensure I’ve covered all of the bases, but I am more comfortable to know that the money I’m saving up for this endeavor will go to a practice that truly deserves it for the unrivaled service and care they provide to their patients.
