During my last visit to my orthodontist, I was fortunate enough to have Jisselle perform the work required. As always, she was awesome. Jisselle is very professional; she explains what needs to be done and provides valuable guidance to ensure I comprehend each phase of the procedure. I feel comfortable with Jisselle, she is easy to speak with; her wealth of knowledge, skills, caring persona and professionalism is very much appreciated. Dr. Newman DDS has a great rapport with the staff and a calming presence which goes a long way for me. The facility is always clean, a pleasant environment and well organized. Overall, I have complete confidence in Jisselles’ abilities to efficiently perform the work necessary while minimizing any discomfort. She is an asset to the dental practice… I highly recommend Dr. Newman DDS and his team.

I initially became familiar with Dr. Newman when my son got braces. He did such an awesome job when I decided I wanted to improve my smile, I decided go to him! I am so pleased about my much my smile improved with invisalign! The attention I received from him and his staff was exceptional! I highly recommend for both children and adult orthodontic needs.

Dr. Newman’s office is so professional and staff are so sweet and caring. My daughter was so nervous about getting her pallet expander. The staff were so gentle and understanding. Dr. Newman was patient and so kind. I highly recommend this dental practice to anyone looking for a fantastic Orthodontist.

Best orthodontist and staff . I love everyone that works there. I had braces as a kid and my bite never looked the way it does now. It looks perfect. I am 33 years old and I never felt better. Dr. Newman did an amazing job. Thank you all soo much for putting up with me and all my questions … and my corny jokes I definitely plan on stopping in from time to time to visit the staff. My friend decided to go to another orthodontist that was charging her a cheaper price for her braces and I have to say in comparison, you get what you pay for. She wasn’t happy with the service and results. If you want braces done right , I suggest Newman orthodontics ! You won’t regret it!

Love Newman Orthodontics! Dr. Newman and Giselle are the best. They are very detail oriented and make sure your teeth are looking the best they can. Giselle always remembers/caters to certain things I like when I’m in the office and it means so much. Highly recommend this dynamic duo!

Fendi R. from East York, PA (Source: Yelp)


I was attending a conference in Port Washington and was in town for a few days when one of my brackets came loose I don’t live in the area so the first thing I did was call my orthodontist for what I could do because it was starting to hurt. He then told me he had a friend not too far from where I was that could help. Dr. Newman. What I went into his practice everything was effortless. He sat me down and told me how dr. Thomas is a good friend of his any reattach my bracket right there and then. I seem to have caught the office during their lunch break but he still took the time to come and see me. The staff was friendly and everyone was laughing. If I live in the area or even close by I would definitely come to this practice.

My daughter has sensory issues, so when her pediatric dentist informed us that braces were NECESSARY (not just for cosmetic purposes) I went into panic mode! My daughter had had difficulty even having x-rays taken at the dentist. I didn’t know how we were going to get through this. I started by talking to other parents looking for recommendations. I am so grateful that we hit the jackpot on our first try! We scored with Newman Orthodontics! My daughter is not an easy patient, but they have always worked to accommodate her needs. This has included only putting a few brackets on at a time, avoiding using retractors whenever possible, and giving her a stress ball, just to name a few. Most importantly, however, is that they have a very skilled and compassionate staff. That has made all the difference in my daughter’s ongoing treatment. I have already recommended Newman Orthodontics to several friends. They are the best of the best!

Both of my children (8 & 16) go to Newman Orthodontics for braces & “after-braces” care. My 8 year old is nervous and shy when going to the dentist and I cannot express how wonderful the ENTIRE staff at N.O. is! From the front desk, to the assistants, to the Dentists themselves… everyone is smiling and has a pleasant disposition. They are VERY patient and take the time to express (in terms an 8 year old can understand), exactly what they are going to do and how that will effect the teeth, etc. The entire vibe of the office is relaxed and caring. I’ve visited other orthodontists where they were very nice and had decent results but N.O. results are quicker and of a higher quality. In addition to that, the office will work with families if money is tight and try to find the best options available to help you get the treatment you or your children need. Highly recommend!

I had a great experience on my first visit at Newman Orthodontics. I was first greeted by Angela Casalino the treatment coordinator. She was great. Angela took her time to explain the procedures and to choose the right braces for my individual case. Doctor Newman and all the staff are very professional. I highly recommend it to anyone who wants to better their smiles.

Sierra L. from Hempstead, NY (Source: Yelp)


This Dentist Office Makes You Feel Like Family , its amazing. The Staff Is Gentle and friendly they work with you to make sure everything is okay. When i first came here my teeth looked horrible , now almost 10 months in my teeth are looking more and more beautiful making want to smile. I highly recommend anyone looking to get a beautiful smile come here.

Deciding to get braces while in my late 20’s & into my early 30’s was hard enough, but Dr Newman and his staff have done everything they can to make my orthodontic process comfortable, simple and effective. Dr Newman and his staff are diligent, competent and amazingly friendly. Any complications or problems I have run into during my ortho process (some of which were major/extensive problems!) have been handled confidently by Dr Newman and his staff. That includes simple explanations for the process as a whole and even at each new step, all of which have helped to guide me through the care, treatment and expected results of my ortho process. The staff is open, friendly and very professional. I enjoy my time there with them because of the personal interest they take in each and every client. They say hello and know your name, they smile and greet you, they say goodbye, and all the while they are doing their jobs professionally. The office is also very family friendly and has recently been renovated. The space and office are clean, open and in no way intimidating. The overall experience and care I have received while going to Dr Newman & his staff has been nothing short of excellence. That will show from your first visit & consultation to your last day in his office for care.

My son had his braces done at Dr Newman’s practice and I decided to get braces myself, because I really trusted and liked the way they work. The practice is super cleaned, the assistentes are the sweetest and Dr Newman is always willing to listen to his patients concerns. Highly recommend them.

Meghan S. from Glen Head, NY (Source: Yelp)


I am so happy with Newman Orthodontics. I had braces as a teenager but never wore my retainer. As an adult my bottom teeth shifted. I was nervous needing braces again as an adult. My experience has been great. The office is beautiful, the staff is professional and I never wait. His prices were competitive, as well. I have four young children and they will be getting their braces their in the future!

Derek M. from Glen Cove, NY (Source: Yelp)


I have been coming to Newman Orthodontics for 3 months now and it has been a great experience so far. The staff at the front desk, both Tanya and Re’Anna, are extremely courteous, accommodating, personable and also very understanding. They will take their time in answering any questions you should have, whether it be appointment wise or orthodontics related and to the best of their ability. All of the other staff and doctors are very kind and professional, working hands on and one on one with each patient, which makes for a very comforting experience. You can be at ease and relax regardless of what procedure you are having done and know that you are in good hands. I would highly recommend them to anyone whom should need orthodontic care. They are more than capable to handle your personal situation whatever it may be! 100% would refer to others! Thank you Newman Orthodontics!

Rose L. from Carle Place, NY (Source: Yelp)


I’ve been going to Newman Orthodontics for over two and a half years. First with my son, then with my daughter, and now for my own treatment which started a few months ago. Dr.Newman and his staff are all professionals who are polite, knowledgeable, and care about their patients. They have many appointment options including evenings and even Saturdays. If you have an emergency they will get you in as soon as possible, even if they are booked, they will accommodate you as best they can. I highly recommend Newman Orthodontics for both adults and children.

Dr. Newman and his staff were awesome! I brought both of my kids in to get braces on at the same time and the process was seamless and only an hour. Dr. Newman answered all our questions. The staff was super friendly and patient with the kids. The office is beautiful and comfortable. Nice work Dr. Newman! Highly recommend.

Neal K. from Elmont, NY (Source: Yelp)


You can be guaranteed of top-notch service and treatment from Newman Orthodontics. Both my kids are under the care of Dr Newman and they love him. He has a gentle approach that makes them feel at ease. From the very first consult with Angela to all of our follow-up visits, we have been extremely pleased with the professionalism of the staff. My daughter’s overbite made her feel very self-conscious. With Dr Newman’s innovative treatment plan, she has no qualms about flashing her beautiful smile now. He was also able to convince my teenage son, who by the way did not want to get braces, that he should. Newman Orthodontics makes a visit to the dentist seem like fun!

Dr. Newman is so great! His team is always helpful and friendly. Daisy is my absolute favorite! I go every two weeks so I’m there quite often. She takes such good care of me and is helping me fly through this process. I’m going every two weeks because I want to be aggressive with my treatment and have my braces off ASAP! Definitely taking my daughter here for when she’s ready for braces!

Ava Kuhn (Source: Google)


Newman orthodontics have helped me tremendously! When I first came here my teeth had a overbite and were extremely spaced out, now they are looking better than ever. They have the sweetest team that always helps and teaches you what is happening with your teeth. I am having an amazing experience here and would recommend coming here to everyone.

Leda A. from East Norwich, NY (Source: Yelp)


Outstanding orthodontist and office! Up to date with all the high tech medical devices related to their work. Knowledgeable and very friendly staff. The office is run like a well oiled machine. My son had braces and Dr Newman projected 18 months and he was spot on. I was so impressed with the whole process I am now doing Invisalign for my shifting teeth. It doesn’t get better than Dr Newman and his office !

Danielle P. from Manhasset, NY (Source: Yelp)


Dr. Newman is a superstar in every way. He is extremely skilled at what he does, and he is also one of those rare professionals who is just a pleasure to work with. He is very personable as well as caring and comforting. I would highly recommend him for anyone who has children who tend to be anxious with dental procedures, and he is great with adults as well. His office staff is highly efficient and maintains a clean and cheerful environment. It was never difficult to schedule appointments and any emergencies, such as broken brackets, were handled promptly. Dr. Newman gave me the smile of my dreams! I was advised by other doctors to have an imbedded adult tooth removed and to have an artificial tooth implanted in it’s place. Fortunately for me, Dr. Newman was confident that he could save the tooth and bring it down, thereby avoiding an unnecessary surgical procedure. I receive many compliments on my smile and respond by recommending Newman Orthodontics to anyone seeking superior results.

Diana Horn (Source: Facebook)


Daisy is terrific! Whenever she cares for me she is gentle, explains everything and I never have a problem, which unfortunately I can’t say the same about some of my other visits! Dr Newman is great and is always available to respond to my concerns!

My son had complex cross bite issues and a very narrow palate with significant crowding. We consulted with 6 orthodontists who insisted he needed to either have jaw surgery or a palate expander with anchorage devices in addition to teeth being pulled out. We were fortunate enough to then be referred to Dr. Newman. In our free consultation session, he was very kind and patient spending over an hour looking at Andrew’s teeth and listening to my concerns. He recommended self-ligating brackets which was the least invasive option. This option requires a lot of patience and expertise but is also less costly than the options other orthodontists offered. Within a few months we noticed incredible improvement and to date my son’s teeth have been transformed beautifully. In addition to Dr. Newman’s technical brilliance he is always kind and patient with us regardless of how busy he is. His staff is also very warm, competent and diligent. I am not one to blog or write reviews but I felt compelled to write this one. He is an amazing orthodontist with a compassionate team and we highly recommend Newman Orthodontics.

Dr. Newman and his team are absolutely amazing! Angela was very knowledgeable when explaining the braces process to myself & my 16yr old son. Dr. Newman took one look in my son’s mouth & knew exactly what needed to be done. Within the next 5 minutes my son started the process! YES, I would recommend Dr. Newman!!

Michelle L. from West Hempstead, NY (Source: Yelp)


We have had only positive and pleasant experiences with Newman Orthodontics, from making appointments, to short wait times, to kind and friendly staff and clean, organized work spaces. They know us and my son by name and are always helpful when I need to come in quick b/c my 9yo’s brace fell off because his molar fell out, or whatever may happen. Then they also adjust his braces and reschedule a new appointment for us! Taylor is sweet as pie and the ladies up front are pleasant and accommodating. We were referred by a family friend and will definitely refer others to them!! Michelle LaForest and family

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


What’s not to like! From the moment you walk in and are warmly greeted by the receptionist to the dental technicians who are so attentive to all your dental needs & concerns and of course to both Dr. Neuman & Dr. Shenis who make sure that everything is done perfectly-we have always had a positive & painless experience every visit.  The office is immaculate and the decor is lovely with a modern flair. My daughters braces are off and her teeth are perfectly straight. We are so pleased with the care we have received and highly recommend them!

John A. from East Meadow, NY (Source: Yelp)


I am extremely pleased with Newman Orthodontics. The staff couldn’t be nicer or more professional. I’m a firm believer in “you get what you pay for”. The price may be a little above the rest, but the facility and service are way, way above the rest!!! After all, aren’t your loved ones most treasured in your heart? And aren’t they worth the finest in the business? I highly recommend Dr. Newman and his entire staff, they are assuredly the best.  John A.

Theresa D. from Franklin Square, NY (Source: Yelp)


Always a pleasant visit at Newman Orthodontics. There is never a wait (even if we are a bit late for our appointment). Our last visit was especially great, because my daughter’s technician explained step by step as to what she was about to fix on her braces. She was really sweet. I’m taking the time to write this, because many kids already feel uncomfortable going to the “orthodontist”. Everyone here makes the patient (and parent) feel relaxed with their warm smiles 🙂

I started my treatment about a year and half ago and I must say that I am absolutely in love with my results. The staff is very professional and welcoming. Jisselle, Daisy, and Dr. Newman has worked well together to make my smile come together and I really appreciate their work!!! I will recommend them to everyone I know!!

B DR (Source: Google)


I would highly recommend Newman Orthodontics! The staff is the best, very knowledgeable, attentive and friendly too! I’m always impressed with the cleanliness and efficiency of the office. My husband and I just finished our Invisalign treatment. The whole process was stress free and easy. The results, amazing! Loved working with Jisselle , Daisy and the entire team. Now, we have something to SMILE about!”

Maria A. from Garden City, NY (Source: Yelp)


So far I have to say that our experience with Newman Orthodontics has been wonderful. Dr. Newman is friendly, patient and has a great rapport with my daughter. He made her feel comfortable and at ease.  The staff is friendly and helpful and they have all made our experience a very pleasant one.  Angela, the Care Coordinator was diligent and wonderful with helping me get insurance approval and they are working with me and have been very accommodating with me on a payment plan for the remainder.  I have read some of the reviews and see that some feel this practice is pricey but I shopped around and have also used another ortho in the past for an older child and I don’t at all feel that Dr Newman’s prices are out of the ordinary. We are looking forward to the end result and thank the entire staff for making this a great experience.  I would highly recommend him in the future.

Nancy B. from Manhattan, NY (Source: Yelp)


My son loves this place. When we found out our son needed braces, we went to the local orthodontist referred by our pediatric dentist. We had a consultation and was miserable. I never get a second opinion but with my son so unhappy and crying with the first consult, I felt I had to find another orthodontist. We talked to other people and was referred to Newman Ortho. We went for our first consultation and haven’t looked back!! The staff made us very comfortable and was friendly. They explained everything to us having no experience with braces. Although it is a farther drive for us, it is worth it.

My daughter and I both had great experiences with Dr. Newman and his staff. They are all very friendly, welcoming and knowledgeable. Jiselle is the best she has a way that makes you feel very comfortable in the chair. The office is always very clean even before covid. I highly recommend Newman Orthodontists.

Claudia S. from Long Island, NY (Source: Yelp)


My daughter went to Newman Orthodontics and when I saw the result once her braces came off, I KNEW I had to have my teeth corrected, too. The office is bright and very modern — with the latest technology. I never wait long when I have an appointment and there is never a problem if I need to change my appointment. The staff is AMAZING! Everyone is extremely friendly and treat you like family. I am currently in treatment at Newman Orthodontics and, after only 5 months, I have seen a huge improvement in my smile. Dr. Newman is wonderful. He greets you with a smile every time he sees you and answers any and all questions you have. I have recommended many people to Newman Orthodontics … and will continue to do so!! Thank you to EVERYONE at Newman Orthodontics!
