Dr Cournot and Dr Lee built not just an amazing dental care office but an amazing place period. Highly professional but at the same time kind and compassionate. I still don’t like going to the dentist but I’m actually exited to see all of them, every time I come.

Spencer R. from Manhattan, NY (Source: Yelp)


I have been going to Dr. Cournot and Dr. Lee’s office since 2003. Not only are they some of the nicest people that you will meet, but they do a terrific job. They are extremely thorough and make sure you are always well taken care of. They are always able to accommodate my busy schedule. I would highly recommend Dr. Cournot and Dr. Lee and their entire staff whether you are just looking for a checkup or have a more serious issue.

Jeff K. from New York, NY (Source: Yelp)


Dr. Lee is the best!  I was looking for a new dentist because the last one was telling my I had 13 cavities and needed to get them all fixed immediately and pay cash for it.  Fortunately I was referred to Dr. Lee, and she is the best and the most ethical out there.  I would recommend her for anyone.  Everyone in her office really loves what they do.  And I’m currently getting some dental work with her periodontist, Dr. Pastaglia, who is also exceptional in every way.  Great office!  You can’t do any better than this place!

Eleni B. from New York, NY (Source: Yelp)


Dr. Lee, Debra and the entire team at this practice are fantastic!!! For most of my childhood I had the same dentist in NJ and couldn’t quite find a place a felt comfortable in NY until I find this practice. From the receptionist, to the hygienist and the dentists, they really care and take the time to get to know you. I loved the thoroughness of even the initial visit when Dr. Lee writes out a report allows you to track your progress from your very first visit. The equipment is state of the art and they explain every aspect of the treatment. I initially started going to this practice because of a patients experience in a Yelp review that said they were helpful with TMJ. My first visit was January 25, 2015 and in that time Dr. Lee and Debra Castro have been helpful in exploring options to control my TMJ, jaw unlocking and grinding. They were also able to help get me a new retainer when my dog ate the old one. Thanks for everything!! It’s definitely a team of wonder women!!

So I haven’t been to a dentist in 17 years. I did however have my teeth cleaned by my sister 3 years ago while she was doing her residency (yes my sister is a dentist lol) so I am not totally disgusting. Recently I had some tooth pain and decided to go to the dentist. I skipped through all these ads ($70 cleaning and xrays and groupon specials but decided against going to one of these franchise dentists. I have heard horror stories of dentists doing shoddy work and their patients paying for it later on. (one of the reasons I went was because one of my friends went to one of these hack dentists who told him everything was fine, 6 months later he has intense pain goes to a different dentist and boom 7 cavities and he needed 4 root canals. I heard about Dr. Lee through some friends @ a local murray hill bar and decided to give her a try. Day 1 Consultation Very easy to schedule an appointment with Jen the receptionist. I had a consultation. I was told the consultation would last 2 hours. I wondered what we could talk about for 2 hours. Well Dr. Jenny Lee and her assistant (damn i feel bad i frogot her name because she was so nice) met me and went over my whole history. She listened to everything i had to say and we spoke about my teeth care and then the xrays and exams started. Let me tell you her dental assistant was very gentle taking the pictures and xrays. Now mind you i have never seen xrays of my teeth before. She explained everything and even pointed out the trouble areas. Day 2 Cleaning So I had 17 years of plaque and calculus build up that Debbie had to take care of. When my sister did my cleaning it hurt like a mofo, Debbie was very gentle and she got everything cleared up. I wish I was able to keep my pictures to show u guys the before and after to be continued

I have been seeing Dr. Lee for almost a year now. I recommend her to anyone. Dr. Lee takes the time to know her patients and genuinely cares about their dental health. Many other dentists are about one-time fixes when it should be about ongoing care. Dr. Lee likes to do regular check ups and make sure that you stick with the recommended regime. I’ve seen her several times this year. I’ve had fillings and deep-scale cleaning and every time she makes me feel comfortable. My gums are more healthy since seeing her. They don’t bleed as much. When she gives you anesthetic you don’t feel any pain at all. I never use to enjoy going to the dentist but I actually do now. Who knew going to the dentist would be such a pleasant experience. 🙂

J J. from Manhattan, NY (Source: Yelp)


Best dentists ever. I’ve worked with them since the 1990s.  Dr. Cournot is amazing and her associate Dr. Lee is too. I am not kidding, I love going to the dentist! I used to avoid it because it hurt–Debra is so gentle and careful I actually feel more relaxed after a dental appointment than after a spa treatment. Not making this up. Best. Dentists. Ever.

Omar O. from New York, NY (Source: Yelp)


When Dr. Lee has a mission there is only one word that needs to be said… Accomplished! On my initial visit, she performed a comprehensive exam to get a complete record of my teeth. We then talked about the best ways to improve my oral health. I followed her plan and now I’m cavity free in just a few visits! Yes, too much candy 🙂 Dr. Lee is a great dentist. She has the best technology which allows her to show you what’s happening with your teeth inside and out. She is caring and professional. I know that Dr. Lee is the best in the business!

Mandy W. from New York, NY (Source: Yelp)


I am hoping this is the same Dr. Lee that I saw today at West 57th Street Dental Association. If so, i just want to say she was simply amazing. I have had my share of nightmare dentists; I couldn’t have asked for anything more with Dr. Lee. She was extremely thorough, helped me to feel comfortable (which is something new for me), and made sure that I understood every action that was taking place. This was honestly that absolute best experience i have ever had with a dentist, and I owe it all to her. Thank you for restoring some faith and ease in the dental experience.

Leslie P. from Manhattan, New York, NY (Source: Yelp)


I’ve been a patient of Dr. Cournot for 20 years. I starting seeing her when I met someone who comes in from NJ to see her – figured if she was making the trip I should check it out! I have terrible teeth, and over the years have seen many (many) dentists with good/big reputations. None of them, however, were interested in my overall dental health. Dr Cournot, Dr Lee and the hygienist Deb focus on this – and it’s had a huge impact. Deb (hygienist) has played a major role – I’ve learned so much from her, and she’s reinforced my motivation/caring about my overall dental health. They have a wonderful staff, and will do whatever they can to accommodate you. I do feel like part of a ‘family’ (in the best possible way!!:) – they care about and take the time to get to know you. I joke with them (but it’s no joke) that I tell people I love my dentist!! I get some funny looks – but have never heard anyone else make that claim! I only wish i had started seeing them sooner.

Maddie E. from Brooklyn, NY (Source: Yelp)


This is one of the best dentist offices I have ever been to. The whole team, from the receptionist to the head doctors are extremely personable, kind, knowledgeable, and all around great. I highly recommend this dentist to anyone and everyone. I met with Dr. Cournot for my initial visit and she was thorough, attentive and answered all my questions. She gave me options for the future of my dental care and gave me numerous recommendations to keep a healthy smile. Please go here! Dr. Cournot and Dr. Lee are really the best.

Christina M. from New York, NY (Source: Yelp)


My favorite dental practice of all time! Dr. Lee and her staff have been immensely kind, gentle, and supportive when it came to my TMJ and history of bad dental work. Everyone is incredibly mindful of their patients and work together to get your teeth back on track. The only caveat is they don’t take insurance, but they will work with you and your insurance company. Otherwise, I will always recommend this practice.

Monica N. from Flushing, NY (Source: Yelp)


Dr Lee is amazing! I did not feel not scared of the dentist anymore. She’s so welcoming and what I loved was how she explained what she was doing to my teeth (in terms of the process). So my story goes where my gums were just horrible and I neglected them for just too much. The day I decided to go to the dentist was when I was talking to my coworker and he said Monica you’re teeth are bleeding. How embarassing. It’s just poor neglect to your body. Overall I felt like ahh I have to hide my mouth when talking to people. It just was awful. My friend recommended me a great dentist spot and I went and that’s where I met Dr.. Lee.I got a scaling done of my whole mouth in one sitting. I said just do it all. Do what you got to do! It was a lot of pain but so worth it. My teeth have not felt so great in a year I would say. After 3 months I went back to see Dr. Lee today to check my gums out and they are SO much better. Dr. Lee taught me how to brush my teeth again (funny how that sounds) which helped out a lot. So don’t be scared of the dentist! Dr. Lee is amazing has helped me out so much not from just helping my teeth but to also helping me gain my confidence back.

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


After my decade of 20-something dental care neglect, I was at risk of squandering everything my parents had invested in my teeth. Not a day too soon, serendipity brought Dr Lee to my rescue! For nearly ten years now, her and Dr Cournot’s marvelous office staff have supported and encouraged me through a total rehabilitation which I see paying dividends every day…and will continue to do so for the rest of my life!

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


I can’t express enough what a relief it is to have found Dr. Lee and the staff at her practice. From the very beginning they answered all my questions and were so helpful in organizing and explaining my financial options for treatment. Dr. Lee has been unbelievably kind and communicative. She really made me feel like my concerns were being heard and even wrote out a plan of action to make sure we were on the same page. Coming from seeing multiple dentist this past year, who outright told me I was just overthinking my discomfort, this is exactly what I was looking for. What initially began as a botched filling done by one dentist turned into a series of unnecessary bite adjustments from others. I was told that nothing could be added to my teeth, only taken away, but I now know there are other options to building my bite back up into a comfortable position. The constant jaw aches and sensitivity due to continuous chipping on the surface of my teeth was pretty painful but thankfully I’m starting to see the end of this ordeal coming soon and I could not be more excited! Dr. Lee and Reina truly make the room a safe space and I feel I can trust them with the health of my mouth, which is a big part of this process for me. They also use some of the most modern tools I’ve ever seen in a dental office and took photos at every step. Seeing these helped me feel aware and included in my treatment. I’ve had a few fillings redone so far, an in depth cleaning and after taking impressions have started wearing a deprogrammer. This has FINALLY given my jaw and teeth some serious comfort and support. I’ve been very anxious about the future of my teeth since this all started, as I had never had any real issues with my mouth before. So I feel very lucky and grateful to have found this office that gives me hope this will shortly be a problem of the past.

Ben T. from Manhattan, NY (Source: Yelp)


Dr. Jenny Lee is far and away the best dentist I’ve ever been to…and I’ve seen many in her trade.  Not only did she identify and perfectly (and painlessly) fix multiple cavities that were slightly hidden under my old fillings (and that my other dentists had no idea even existed), but she always made me feel comfortable and welcome in her amazingly warm and fun office.  I actually look forward to going to see my dentist now, because of her and her exceptional team!  Now that all of my cavities are taken care of, I’m considering eating jolly ranchers on the regular just so I can have an excuse to come by the office again 🙂

Carena L. from Manhattan, NY (Source: Yelp)


Dr. Cournot (and Dr. Lee) is a true professional, so passionate about what she does, is so caring and considerate, and is so good at what she does. The experience is like going to a top notch spa for your teeth, and after seeing the difference, you would never want to go back to anything less. From the first visit when you realize how much there is to look at and discuss about your mouth, to when you actually need something done, you are in good hands, and can feel confident you are getting the best treatment and what is truly appropriate and mutually agreed upon. Even thought they don’t take insurance they immediately bill your insurance and I’ve gotten checks back within days of my appointments… I highly recommend.

Alexis P. from New York, NY (Source: Yelp)


Dr Cournot and her team are caring and professional in the extreme. I have had 4 dentists in NYC and she is by far the best. Setting up the appointment was easy and thorough. The staff are interested, showed genuine concern and were kind. Dr Cournot is obviously knowledgeable but also takes the time to make sure you understand what is happening with each step. I visited with very painful and distracting pain from TMJ, we attended to the immediate concerns to get me comfortable. I will continue to visit their office to manage the TMJ (I may also see Dr Lee who is following my case and has touched base with me) but I am also planning to have them do dental work on my old fillings and crown. I trust them completely and know I’m in good hands.

I’m a dentist, and I went to Dr. Lee’s office for my exam and cleaning. They take their time and do all the extra steps to make sure the job is done right. I would recommend this office to anyone who wants to receive a higher quality of dental care in a comfortable and friendly environment. The hygienist also did a great job and was very thorough.

Lynne B. from San Francisco, CA (Source: Yelp)


I have gone to Colleen Counot’s office for about 30 years. She has changed me from a dental-phobe to a completely trusting patient. She is marvelous – kind, caring, painstaking and extremely competent. Everyone in her office – from the front desk to her associate Dr. Lee to Debra Castro the hygienist – is also of this highest calibre. I recently completed a crown at the back of my mouth. Gagging is a very difficult problem for me. But as is usual in this practice, Dr. Cournot and her dental assistant Eileen were attentive to my concern and most responsive and creative in helping me through the procedure. They really made it possible – and comfortable! – for me to do this. Not to mention giving me a new tooth that feels totally at home in my mouth. When you are a patient in this office, you’re in the best of hands.

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


I have been living in NY for over 10 years and this is my 3rd dentist’s office that I have visited. Now I can only wish it was the first one because I am extremely happy with Dr. Lee and her entire office. Even thou I am still not done with all treatments, I can already notice a huge difference with my teeth. She is very detailed, knowledgeable, and extremely kind.  I highly recommend this dentist to anyone who is looking for a great dental service and a place that they can trust.

Manda C. from Brooklyn, NY (Source: Yelp)


I went to Dr. Lee yesterday mainly for my TMJ issue after reading a review from Yelp. I’ve been to a few dentist/orthodontist for my TMJ already, and so far, none have helped and I personally feel that none have spend enough time and energy to help me solve my issue. Dr. Lee was so thorough with my initial consultation. She asked me any and all questions that can possibility cause my TMJ. She is just great. The whole office staff was super friendly and kind. Obviously my TMJ issue have not been resolved yet since I just went in yesterday, but Dr. Lee gave me some instruction to follow until the next follow up. But I can definitely say that I am in good hands.

Jeffrey W. from Brooklyn, NY (Source: Yelp)


I was recommended to Dr. Cournot a few years ago by a friend and have been hooked ever since. Now, I DO understand that people dis-like going to the dentist, but Dr. Cournot (and now Dr. Lee as well) and the entire staff of the office is the antithesis of  “going to the dentist “. Everyone makes you feels SO comfortable and cared for and that makes one feel good that you are taking care of your oral health needs. I consider it a spa treatment of sorts !  The skill, care and comfort emanates from everyone in the office. If you are a person who has put off going to the dentist ? DON’T – book an appointment – let Dr. Cournot, Dr. Lee and the staff take care of you too !

Lisa C. from Astoria, NY (Source: Yelp)


Dr. Jenny Lee’s is the embodiment of a new era of dentistry. Her practices prides itself on being comprehensive and that is exactly what they are. Gone are the days of dreading sitting in the dentist’s chair. You are instantly put as ease by her ability to make you feel that you are apart of the process. From the initial examination, during which she x-rays, photographs, probes and documents what seems like every inch of your mouth, to follow ups, fillings and the like, Dr. Lee treats her patients like partners and not just a mouth full of teeth. She is very knowledgeable, extremely considerate and thoughtful. It makes you wonder if you are getting special treatment. Everything about their office exudes a air of calm without being obnoxiously about it. Her staff exudes professionalism, patience and kindness. Their ability to cater to your needs, questions and concerns is refreshing in an industry where sometimes offices become like factories. It’s almost as though they never forgot what it is like to be a patient. They are so helpful for out-of-network patients. A HUGE plus! This is like no other dentist office I have ever experienced. No longer are dental visits something to stress about or avoid.

Elisabeth A. from Westport, CT (Source: Yelp)


I feel extremely blessed to have Dr. Cournot, Dr. Lee, Deb (the best hygienist ever), Eileen and their office staff in my life. In particular, I am indebted to Dr. Colleen Cournot who has been my dentist for well over 20 years. In addition to being a supremely gifted dentist, she is a kind, sensitive, compassionate being who has managed to create an oasis-of a-dental-office a few blocks from Grand Central station in NYC. As someone with highly sensitive teeth & significant dental issues, I always feared going to the dentist and associated a visit with significant discomfort & pain. However, ever since I became a patient in the Cournot/Lee practice, I actually look forward to the appointment since it gives me an opportunity to spend time with their good energy while receiving the best possible care available. After decades of being in their care, and being the recipient of many compliments from other providers regarding my “exquisite” dental work, I have supreme confidence in the quality of their work. From their well-appointed and comfortable waiting room offering tea, coffee and a shelf dedicated to books written by some of their impressive patients, to the extremely sophisticated state-of-the-art imaging equipment….the whole office experience feels like it was masterfully conceived by a team of people who care very deeply about each and every individual entering their office. I can’t recommend Dr. Cournot, Dr. Lee, Deb, Eileen and team highly enough and wish everyone could have the experience of being in their capable hands. As this is not possible, perhaps their supremely peaceful and impressive practice could be regarded as a model for replication…so many would benefit!

Katie C. from Brooklyn, NY (Source: Yelp)


I started going to Dr. Cournot last summer and have had only great experiences with my office visits. Literally every person who works there is friendly and extremely helpful – from the receptionist to hygienists and of course Dr. Cournot and Dr. Lee! They really take the time to learn about you and your habits to provide the best dental advice and service possible. They explain everything they do and why they are recommending certain treatments or care, rather than just telling you to do something. I couldn’t ask for a better dentist’s office!

Sj H. from New York, NY (Source: Yelp)


It is rare that I would call a visit to the dentist a pleasant experience, but it was a 5 star experience.  I highly recommend seeing Dr. Lee, she is warm, highly informative, and extremely gently and concerned about her patients.  The office is inviting and the staff is super kind and very friendly.  I had the most comprehensive exam of my life (medical exams included)!  I received a written report with pictures from my initial exam with follow up cleaning and future maintenance.  So happy I finally went and feel assured that every nook and cranny of my mouth was examined for optimal health. My fear of going to the dentist has disappeared!

Inessa S. from Brooklyn, NY (Source: Yelp)


My coworker recommended Dr Lee and since the office was conveniently located near my office, I gave it a shot. I have been a patient for over 4 years now. Dr Lee not only knows everything about my dental health but also about me on a personal level – she takes the time to truly care about every patient. She constantly goes to conferences to stay up to date. The technology and organization of the office is impressive. The dental hygienist Debra Castro is very attentive, gentle, and works really well with the doctors. She too is very personable and I wouldn’t want to go to anyone else. The front desk staff are knowledgeable and friendly.

Margarita M. from New York, NY (Source: Yelp)


After not going to the dentist for several years, I was a little apprehensive of what Dr. Lee might find. But she put me at ease immediately by explaining what she was doing every step of the way. The exam and cleaning was painless and even relaxing! I really appreciate the time she took with me. Definitely the best experience at the dentist’s by far!

Liza S. from New York, NY (Source: Yelp)


I can’t say enough good things about this office. Dr. Lee is not only an incredibly talented dentist, but such a caring person. I have struggled with serious TMJ for years, and she was the first dentist I encountered who empathized with my condition and made an effort to help in any way possible. The entire staff is kind, professional, and skilled; I can’t imagine there’s a better dental office out there!

Tali S. from Brooklyn, NY (Source: Yelp)


I have been a patient of Dr Cournot and Dr Lee’s for over seven years and have been very happy and deeply impressed by the attentiveness and skill of their care. I have very sensitive teeth and very sensitive hearing, so dental work is my version of torture. Dr Cournot has an incredibly gentle and accurate touch, and she does things in a way that regularly surprise me with how considerate and gentle they are. She understands that dental work, with the cold air blowing on your teeth and cold water and suction, can be very uncomfortable and she takes great pains to cover or protect teeth that aren’t being worked on. Her work is beautiful, she has great hands and is very attentive to detail. And she gives the most pain free novocaine I’ve ever received. Her explanation of dental issues and diagnoses always make sense and seems reasonable to me, and I have come to trust her judgment. I used to dread going to the dentist and have never experienced such consideration for the patient’s experience as I have in this practice. Having found Dr Cournot, I have been able to take care of dental issues with a minimum amount of stress. Dr Cournot is always available via email and responds to questions or concerns within a few hours. And she often reaches out after an appointment to make sure that I’m recovering well. I feel very lucky to have found Dr Cournot and Dr Lee and am grateful for their care.

Deb C. from Secaucus, NJ (Source: Yelp)


I think the most outward change since I’ve been under the care of Dr.Cournot and her team, is my smile. I notice it in every picture now. My smile stands out to me, not only because I love the way it looks but it’s in perfect harmony with the rest of my face. It’s so natural. I remember the challenge Dr.Cournot faced when she began to treat me. The task was a great one. Dr. Cournot had to first figure out my original jaw position and then restore my teeth to their former height. I was constantly chipping my front teeth and cracking my back teeth because I had worn down my teeth from grinding and clenching them together while I was sleeping. My jaw was in constant pain because my bite was so uneven. When treatment was completed, it all came together beautifully. Dr. Cournot has a keen eye for esthetics combined with an extensive training of how the teeth and jaw should function. I am no longer in pain nor do I chip and crack my teeth. The result has been life changing for me. My treatment was also supported by a talented team which included Dr. Cournot’s partner, Dr. Jenny Lee, and their dental assistants Eileen, Illiana and Reina. Jennifer and Kim are the administrative dynamos who helped me schedule my visits. Dentistry is very tough for me. These women were my rock as I went through this incredibly personal experience. There are no adequate words to express how cared for I felt throughout this journey. As the dental hygienist for CournotLeeDDS, I have seen many beautiful smiles come out of this practice and now I have one too!

Amr S. from Cupertino, CA (Source: Yelp)


It’s no surprise Dr. Lee is selected as one of ‘America’s Best Young Dentists.’ Her professionalism, friendliness and approach to dental health is unlike anything I have seen before. Dr. Lee really does an amazing job explaining what work needs to be done, what are the root causes of the problems you have and lays out all the treatment options. Dr. Lee’s approach is transformative – it redefines what a trip to the dentist should be (reason + experience). Dr. Lee didn’t just leave this positive impression on me. Even my wife and kids (7 and 11) had a great experience. Thank you Dr. Lee and thanks to everyone working at this friendly and cozy office.

Paul D M. from Woodside, NY (Source: Yelp)


Dr. Lee is an exceptional dentist and has mastered her profession at such a young age.  At first sight, she seems to be fresh out of college but after a brief introduction you realize that she is a well tenured professional.  Her comprehensive exam is just that very comprehensive. As for her assistant Eileen, she is an incredible human being with a great big heart.  She carefully and painstakingly took my x-rays providing every comfort (She even gave me a stuffed monkey named George to hold).  I would have never imagined getting such impeccable and thorough treatment at a dental office.  As the exam continues, Dr. Lee draws your attention from the onset and takes away any preconceived notions or preexisting fears that you may have of dentistry.  She begins her examination by carefully reviewing your dental and medical history with you and then proceeds to making assessments based on her findings.  She carefully explains her findings with you allowing you every opportunity to participate in the process.  Her approach to dental care is next to none and her persona is infectious.  I can’t wait for my deep cleaning next week (I hope it doesn’t hurt ).

Marice M. from New York, NY (Source: Yelp)


Can’t say enough great things about this practice! The patient coordinator Jen was very friendly and made me feel comfortable on the phone and in person when I came in. She took her time answering my questions regarding my financial concerns and even offered several options including the option of payment plan when it was time to check out. Although it wasn’t necessary, she was very attuned to any concerns I had. The dental hygienist Deb was super friendly and so attentive and interested in our time together. Our interaction was engaging that it made me feel more relaxed and invested in my cleaning. She helped me understand my progress since my last appointment and offered attainable solutions to meet new goals in my prevention plan
