Both of my kids have had wonderful experiences with Dr. Stoess-Allen. Her entire team is truly invested in the well-being of their patients and consistently provides the highest quality care. Being able to trust that both doctor and staff have my children’s best interests and best smiles at heart is comforting and makes our visits a pleasure. My youngest gets her braces off in 2 weeks, after just a year, and can’t wait to show off her new, beautiful smile.

The treatment I’ve received with Park Avenue Orthodontics has been world class—second to none. The alignment of my teeth and my bite have improved dramatically. They’ve worked with me to achieve the exact outcomes I had in mind. I’m glad to say the entire staff has remained consistent throughout my whole treatment, which is great because they’re all very professional and pleasant. Five stars.

Park Ave Orthodontics staff has been a pleasure. Appointments are timely and there isn’t a wait which I rarely see with other doctors. They are very accommodating with scheduling and my daughter has seen improvement in the issues they are addressing. Would highly recommend.

Park Avenue Orthodontics offers the ALF appliance which is a much better method for pediatric palate expansion than the old, “Elizabethan torture” devices that are bulky and require a key for cranking.  Both of my sons used the ALF appliance and went on to have braces and now Invisalign to correct their respective overbite, underbite and crowding.  My son with the overbite had a severe case and the treatments have corrected this.  I highly recommend this practice.

From the outset, I have been incredibly impressed with the Park Avenue Orthodontics team. I genuinely enjoy every single appointment! The team is attentive and professional, and strive for perfection. The quality of their work is stellar, and as a result, I am much more confident when I smile. There were multiple issues with the alignment of my teeth and bite, which I was concerned about, but at every single stage, the team has taken me through the progress of my treatment, and what I can expect from the period between each appointment. I am very happy with their quality of work, and highly recommend seeking treatment with the team!

Dr. Stoess-Allen is currently treating my fourth child, so we have obviously been coming here for almost a decade.  I was initially drawn to Park Avenue Orthodontics based on Dr. Stoess-Allen’s choice of continuing education, but we have continued to make the trek into the city due to the quality of the work and the care they show for each patient.   The staff continue to be great and always greet us with their perfect smiles.

Mae M. from Setauket- East Setauket, NY (Source: Yelp)


I had such a challenging case, most orthodontics on Long Island were afraid to try anything but traditional braces. I knew I needed to find the best of the best that would take a chance on me, and Park Ave Orthodontics is the absolutely best! They always made sure I was comfortable and explained every process to me so I knew exactly what was going on! I work in the industry and was so pleased with the environment and cleanliness of the office. Such incredible, nice, knowledgeable staff members and Doctor Stoess-Allen is truly one of a kind. They gave me a perfect smile!

I have been extremely satisfied with the results so far of my Invisalign treatment. Being currently almost halfway through my 2 year treatment plan I can see major results already. My jaw pain has been eliminated and as my case is rather complex most dentists would not have the skill to do this without fixed braces. The practice is highly professional and the people are super friendly.

My son has been a patient of Dr. Stoess-Allen for the last few years. We love her forward thinking approach to orthodontics. She, along with her whole staff are very sweet, caring and knowledgable. They are punctual while giving every patient their complete attention. My child started with an ALF expander and braces just a few months ago, and we already see a noticeable improvement. We are very happy with our experience and recommend her to all.

I know this sounds cliche but I never write reviews and this honestly is the first one I am writing. My experience at Park Avenue Orthodontics with Dr. Stoess-Allen and staff has been so wonderful that it warranted my synopsis of what has transpired to date. As an adult who required orthodontic treatment I was naturally very concerned about the idea of wearing braces for a multitude of reasons. I found a new general dentist who was trained in treating patients with Invisalign. I had a complex malocclusion involving a cross bite and missing primary molars. He told me my case was too complex for him and referred me to Dr. Stoess-Allen at Park Avenue Orthodontics saying she is a “wizard” and I must see her. He said if there is any orthodontist who could treat my case with Invisalign it was Dr. Stoess- Allen. I have been to one other orthodontist who said my case could not be treated with Invisalign and I was frustrated and had no desire to wear regular braces. He gave me Dr. Stoess- Allen’s information and I called as soon as I left his office. I called and was cordially greeted by Dana the office manager. She was extremely attentive and genuinely empathetic to all my concerns about undergoing treatment and set up my initial consultation. When I hung up I felt good and at ease and knew I was in the right hands before even stepping foot in the office. When I arrived for the consultation I was greeted by Dana and felt very comfortable from the start. Then I met with Dr. Stoess-Allen who was truly amazing. Her whole demeanor was very soothing as she explained everything step by step in precise detail on how the process would work. I knew immediately I was in the right hands. Dr. Stoess-Allen broke down my complex situation into concise logical steps. She said she could correct my bite with Invisalign!! (She is a wizard!!) I was ecstatic after hearing her diagnosis and was ready to start treatment immediately. Once I agreed to move forward everything was explained to me in detail and the pricing was very reasonable. I was then immediately brought into the back to get the whole process started. The whole staff was very friendly as they took my impressions and photos. We actually had a good time. Dana was checking in to make sure everything was copacetic the service was truly amazing. As I am writing this review I am going into my second refinement of Invisalign and have been with the Park Avenue family for almost a year and a half. They really do feel like family! I am absolutely ecstatic about the results I have so far. I never thought I would be able to correct my bite with Invisalign and I am so thankful I found Dr. Stoess-Allen and Park Avenue Orthodontics. We are getting into the fine tuning phases of correcting my bite and Dr. Stoess-Allen really dots her I’s and crosses her T’s. She told me “we will not stop until my bite and smile are perfect” and I would have it no other way. Well to sum things up Dr. Stoess-Allen runs a top notch practice and is one of the finest in her field. I wholeheartedly recommend her and her staff to anyone who is contemplating having orthodontic treatment. I am so happy with my results so far and am even more excited to finish up my treatment and have the perfect bite I have always dreamed of. Thank you Dr. Stoess-Allen and staff! You all truly make me want to smile with all your help so far!

I moved back to New York from Utah and was taken back by the professionalism and courteous staff here.  I had over a year remaining in my treatment plan and it was a seamless transition.  I would recommend this Orthodotic office to anyone I met that was looking for A+ service with affordable care.  Thanks so much Dr Stoess-Allen and staff for making me feel like I am a special person and not just a number.

Jan and her team are AWESOME! Her attention to detail and professionalism are unmatched and her expert use of Invisalign has been a game changer. If orthodontics and modern medicine were the sundae, Jan and her team would be the icing AND the cherry on top. Would recommend to anyone and everyone, 10/10!

A poem written by a patient Dear Dr. Stoess-Alan, Words can’t do justice To the feelings and emotion Towards a professional dentist With unlimited devotion. Beyond the call of duty With perfection and care So patiently, so kindly, So much more than you share. May the work of your hands Forever be blessed And all your endeavors Crowned with success. Continue making people smile As only you can. To a wonderful dentist And a wonderful woman! Thank you for everything!! Sincerely, Mrs. Kohn & Chany

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


I got my braces off today and I couldn’t be happier. I have never felt so secure with smile as I do now. I trust Dr. Stoess-Allen and her staff to the fullest extent. I especially liked that the office has certain days specifically for adults so I never felt uncomfortable about wearing braces at my age. I highly recommend Park Avenue Orthodontics to anyone seeking treatment in New York City and surrounding areas.

Tracy R. from Arlington, VA (Source: Yelp)


My invisalign experience at Park Ave Orthodontics with Dr. Janet Stoess-Allen has been as painless as I could ever imagine. I was able to complete my treatment and gain a perfect smile in less than a year. The whole team is extremely friendly and knowledgable so I always felt like I was in good hands. Would recommend to anyone! An overall amazing experience.

Winny L. from Brooklyn, NY (Source: Yelp)


This review is based on my first visit to this office for an Invisalign consult. Upon arrival, I was greeted and taken inside very quickly. Nice staff, nice office, nice doctor. Dr. Stoess-Allen actually took the time to explain to me all the issues that I had and explained to me exactly what the management would be. In addition, she also took the time to listen to me and allowed me to ask questions, unlike a previous consult I had where the orthodontist just throw orthodontic jargon at me thinking I would understand or hoping that I wouldn’t understand at all what she was talking about. As a self-proclaimed perfectionist, the doc definitely knows what she is talking about and seems to be very attentive to detail and as a perfectionist myself, I trust that I will be in good hands for the next year or so. And like the dude in the previous review said, the office is a pleasant environment and is super clean. We’re off to a good start so far 🙂

Dana M. from New Canaan, CT (Source: Yelp)


Dr. Stoess-Allen is the most generous clinician that I have ever experienced. She and her staff readily give of their time and talent. They are patient and listen as well as readily address any questions and concerns you may have as a patient and sets you, as the patient, at ease. There is a humbleness about her that is refreshing and unforced. I recommend her to all of my patients and will continue to do so. She has done and continues to do beautiful work on both myself, daughter and my patients.  Overall, I look and feel more beautiful thanks to her.

I love this place!!!! I am a nervous wreck when I have to do any procedure on my teeth and everyone in this place made me feel comfortable and safe. Dr. Janet Stoess-Allen is a wonderful orthodontist and has helped my teeth to look amazing and has given me the confidence to smile more. I highly recommend this place.

Lily sold me before I even booked my appointment! As the owner of a dental directory business I can tell you I have met thousands of dentists and staff members. This practice is light years ahead of any office I have visited in terms of friendly service and yes it’s in Manhattan on Park Ave… Imagine that!! Take that midwest and southern hospitality LOL. I cannot say enough good things about my first visit.

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


I love my smile! Finally…in my 50’s… I have a smile I feel great about. I didn’t have the orthodontic treatment I should have had as a child, so I lived with crooked teeth and a misaligned bite for many years. I had often thought about seeking treatment but just couldn’t come around to the idea of braces. When Invisalign became available several years ago, I looked into it, but was told by more than one dentist that it wouldn’t work for me. Apparently, correcting my bite was too complicated for Invisalign. I also have a crown on one of my front teeth, which just added to the complication. All of this changed when I found Dr. Stoess-Allen and Park Avenue Orthodontics. After my initial visit and consultation, Dr. Stoess-Allen assured me she could correct my bite and improve my smile. She did tell me that my treatment would take longer than most (it was almost 2 years), but it would definitely be possible. Her confidence and positivity helped make my decision to go forward an easy one. It was one of the best decisions I’ve made. The treatment was a big success and I couldn’t be happier with the results. Dr. Stoess-Allen and the entire team at Park Avenue Orthodontics were such a pleasure. The atmosphere in the practice is really positive and welcoming. I actually looked forward to my periodic appointments. The team was always so encouraging. I would absolutely recommend Dr. Stoess-Allen and her wonderful team to anyone considering Invisalign.

My son’s case was a full underbite and he never ever wanted to smile.  I can not begin to say enough how the treatment he received from Dr. Stoess-Allen and her staff was life changing. Most patients are anxious for treatment to be completed, for us the results happened almost too quickly because we loved our visits and always knew we were in such great care.  My 3 daughters are now patients too. Becoming part of the Park Avenue Orthodontics Family is something that we will cherish forever!

Park Avenue Orthondist was an incredible experience for me from start to finish. During my consultation, they provided expert advice on the best plan of action, as well as insight into areas that they would correct that I hadn’t even noticed before. Dr. Stoess-Allen is, by far, the most knowledgable and precise orthodontist I have ever worked with (I have had 3!), and I know I have been in the best of care. Every member of the team was extremely polite, warm, and welcoming – I enjoyed coming to my appointments! The time flew by, and I got my braces off much faster than I thought. I’m so happy to have chosen Park Avenue Orthodontist, and would recommend them to anyone who is looking for expert-level care.

My past 3 years at a patient of Dr. Stoess- Allen have been nothing short of wonderful. She is the most comprehensive orthodontist I have ever met— I fly from LA to NYC to see her! Not only is she making my teeth look better and more aligned than they have ever looked in my life (after YEARS of other orthodontists’ work), she is fixing my bite so that my TMJ will no longer run my life. She is an expert in realigning one’s jaw by readjusting the bite. I am not yet finished with my treatment plan— mostly because I take my sweet time with wearing my aligners— but I have more confidence when I smile now AND the pressure that has already been taken off of my jaw is life changing. She is patient, thorough, loving, she listens (which in my experience is less common than it should be) and is simply the best in her field! Five stars in every way.

Park Avenue Orthodontics is currently helping me straighten my smile with Invisalign. Their professional staff is amazing and they use only the latest and most sophisticated technology to achieve the best results. I’m so happy to be a patient at Park Avenue Orthodontics and have referred all of friends and family.

Tylah G. from Lake Grove, NY (Source: Yelp)


I usually don’t write Yelp reviews but for Dr. Stoess-Allen and her staff it is honestly the least I can do. Just for some background- I have a very long and complicated history with dental procedures. I had a traumatic accident in elementary school which left me with two teeth knocked out, one chipped, a fractured jaw and a fractured nose. Since that time I’ve been to countless dentists, surgeons, orthodontists, and implantologists. I have a pretty severe open bite and was told by countless experts that it could not possibly be fixed without jaw surgery. Thank god I did my own research and came across Park Avenue Ortho. Dr. Stoess-Allen is phenomenal. She is kind, attentive, and dedicated. I’m about a third of the way through my treatment and not only has my smile improved, but my confidence has sky-rocketed. I cannot praise her or her staff enough. They are genuinely friendly people who are invested in your treatment plan and satisfaction. I recommend her to anyone who’s even thought about Invisalign because she knows what she’s doing and she truly cares. I cannot thank her enough.

Molly O. from Baldwin, NY (Source: Yelp)


I came across Dr. Stoess-Allen desperate to fix an open bite that had been deemed irreparable without jaw surgery. Convinced this was a misdiagnosis and wanting to explore safer alternatives, a good ol’ Google search led me to her work: a less than 2-minute video showcasing an open-bite much resembling mine that Dr. Stoess-Allen fixed in all of 13 months. I immediately scheduled a consultation. Sure enough, one look at my bite and Dr. Stoess-Allen confirmed it was treatable with Invisalign. I’ll never forget how she walked me through her vision of what my treatment would entail — like a poet or artist describing their creative process! She knew how and what my smile should look like and delivered on her promise. My bite is closed, my speech is improved, and I didn’t have to suffer through through the pain and anguish of jaw surgery. A perfectionist in all the right ways when it comes to orthodontia, I cannot sing Dr. Stoess-Allen’s praises enough. From her incredibly attentive staff to their impeccably kept office, I’d bet there’s no one better in all of Manhattan for those considering Invisalign.

Bruce S. from Toms River, NJ (Source: Yelp)


I can’t stress enough to anyone that has been told only surgery can correct your “open bite”, to please see Dr. Stoess-Allen before doing anything.  We took our son to at least 4 orthodontists and all told us that he would need surgery (cutting the jaw and reshaping it) and braces. We were devastated by the thought of him having to go through all that pain and suffering especially as a 15 year old high school sophomore.  Ironically, it was our son that found a video on YouTube where she used invisalign to correct the open bite.  We called the office and set up a consultation.  From the moment we called, the entire staff couldn’t have been nicer.  It has now been a year and half since he started the treatment and the results are AMAZING! His teeth are now touching, the open bite is gone.  His crossbite has been corrected and he’s into the home stretch of the invisalign treatment.  We couldn’t be happier with the results.  The other benefit to us is that it’s all been done with a limited number of trips into NY.  We live about 2 hours away but with this treatment we go to the office every couple of months on average.  The entire staff is great and will make you feel comfortable from day one.  You are getting the best here. We feel so lucky to have found Park Avenue Orthodontics!!

I would highly recommend Dr. Stoess-Allen and Park Avenue Orthodontics. She has done a wonderful job with both of my children’s teeth over the past 8 years. She is highly professional and patient, and her staff is friendly and accessible. Dr. Stoess-Allen is a wonderful orthodontist, who cares about her patients and is a seasoned professional.

Dr. Janet has treated my sons with Invisalign and we couldn’t have been happier with the service, the result and the staff. Everyone in the office is warm and welcoming. The staff is always very courteous and helpful and Dr Janet is always thoughtful in the treatment of her patients. I would highly recommend her to anyone looking for a wonderful Invisalign experience.

I am absolutely thrilled with my experience at Park Avenue Orthodontics!! I got Invisalign done and it was an absolute dream of a process. Everyone on their staff is incredibly kind and attentive, and they listened to what I wanted and adjusted my plan whenever necessary. I’m so unbelievably happy with how my smile turned out! Make an appointment, you won’t regret it!

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


It’s been a year since my braces were removed and I’m just thrilled with the results! I couldn’t have gotten to this place without the help of one of the best orthodontists in NYC – Dr. Stoess-Allen. When I first stepped into Park Avenue Orthodontics, I was frustrated, distressed and in a lot of pain from my severe TMJ issues. Dr. Stoess-Allen’s expertise on TMJ, along with her highly customized 3-year treatment plan, helped to get my jaw and teeth into a “harmonious” and comfortable position. And no matter what challenges arose, Dr. Stoes-Allen never gave up hope. She’s amazingly determined, confident and caring – all the qualities you look for in a doctor. I can’t thank Dr. Stoess-Allen and her wonderful staff enough for all they’ve done for me!

Marissa P. from Queens, NY (Source: Yelp)


I have only positive things to say about Park Ave Orthodontics and Dr. Janet Stoess Allen…first, I will start with saying that she is wonderful and the only person that has been able to fix my open bite (which I was told would never be fixed without surgery!). Invisalign are relatively painless and easy to wear once you’re used to them. Second, the office is inviting unlike so many other dentists/orthodontists can be. The staff is smiling and cheerful and so patient. I’ve never had a bad experience here and I’m a year into treatment and about a year left and my smile has gone from having a huge gap to almost no gap at all and my teeth straight!

Julie L. from Brooklyn, NY (Source: Yelp)


Dr. Janet-Stoess-Allen, Dana and staff are incredible!  My son’s treatment was tailored to him as an individual and his smile is no longer crowded and uneven. Dr. Janet is also the only doc in the city that uses the Alf appliance for palate expansion.  A much less obtrusive method.  Thank you Park Avenue Orthodontics!

Dr. Stoess-Allen changed my life. No doubt. Seven years ago, I came to her office in desperate need of braces. Multiple doctors told me I needed surgery to correct my overbite, but with the doctor’s innovative approach, the issue was resolved within just a couple years. Now I am more confident and happier in life. Thank you Janet!

Harry J. from Washington, DC (Source: Yelp)


I’ve had the opportunity of being Dr. Stoess-Allen’s patient for the past 10 years! With that, there are not enough good words in the dictionary to explain her, her practice and her exceptional staff! I, unfortunately, developed a severe underbite 4 years ago and was left with little choice other than invasive jaw surgery. Jan luckily stepped in and has worked with me on a monthly basis for the past 4 years, creating an Invisalign plan for me that included more trays and changes than any of her other cases. Her attention to detail, creativity, and absolute professionalism is the only reason I have a perfect bite and jaw line today. Thank you, Jan! For anyone looking for the best New York has to offer, albeit a small or large orthodontic problem, I would recommend Park Avenue Orthodontics without reservation!
