Dr. Greg, the orthodontist, is probably one of best healthcare professionals Ive ever had. Very knowledgeable and charismatic. I was very nervous about getting specific novocaine shots but he reassured me significantly and I barely felt any pain thanks to his techniques! The entire staff is also really friendly and supportive; everyone is so welcoming. 10/10 would absolutely recommend this orthodontist office.
Response from the owner:Thanks, James!
Liz S.
I came today for a consult for braces. This visit was more pleasant than I could’ve even imagined. From the moment I walked in the door, I felt such a kind and joyful energy. People seemed so happy to be working where they were. Everyone said hi to me as if they were truly happy to see me. It was so quick but also thorough and efficient. My options and situation were explained to me in such an honest and realistic way. I left feeling so hopeful and excited! I immediately wanted to go recommend this place to anyone who ever thinks about getting braces for their kids or themselves. Thanks so much for what you do!!
Response from the owner:Liz, it means so much to hear that you felt the joy and teamwork in our office.. We really do love what we do, and we’re grateful for patients like you who make it even more rewarding.
Thank you for trusting us and for wanting to recommend our practice. We can’t wait to see you again soon!

Response from the owner:Thank you so much!! If you're happy, we're happy, too!
Kristy L.
Dr. Greg Gittleman and his staff are simply the best. Dr. Gittleman is not pushy with treatment, but takes time to carefully evaluate our children's unique orthodontic needs. Dr. Gittleman and his staff all know us by name and make our kids feel so at ease and welcome. I highly recommend this practice!
Carolyn S.
I can’t recommend this practice enough. They are kind, thorough, and always make you feel welcome. Upon completion of the visit Dr. Greg also makes sure to explain what was done during the visit and the next steps.
Response from the owner:Carolyn! We are so glad to hear that you guys have enjoyed your visits to our office! You guys are awesome!

I can't say enough about Orthodontic Specialists. We've got more than one kid in braces, and we have always loved going here. We've had only good experiences and would recommend them to anyone. The staff is warm and welcoming, knowledgable ,and friendly. Everyone goes out of their way to put the kids at ease, which is a huge win. You guys are the best at keeping beautiful smiles on faces!

Love Dr. Justin and the team at OS. They are so kind and caring. They take pride in what they do and make their patients feel welcomed and comfortable. We’ve had an amazing experience and are so thankful for such a great practice. My son is so happy with his new smile!
Response from the owner:Hi! We have enjoyed having your son as a patient! His smile is as awesome as he is! Keep shining bright!
Allison D.
Dr. Justin and the staff are second to none! As first time patients, they definitely lived up to their highly recommended expectations. They were kind and caring and explained everything thoroughly to both me and my son. They all came together perfectly as a team and made it effortless and an enjoyable experience for my son. We look forward to coming back and continuing our journey with all of them!!
Tara L.
Such an amazing team. They were very personable, kind, and understanding! They explained things to me in detail and to my 9 year old in a way he would understand! 10/10 would recommend
Response from the owner:Thank you, Tara!!! Your kind words mean so much to our whole office!
Jennifer F.
Wow! From our initial consultation to our many follow up appointments, the staff at Orthopedic Specialists are attentive, organized, professional, and so friendly!

Response from the owner:We appreciate the Fitz family so much! Thank you for taking the time to share about your experience! See you all soon!
Jessica
Very nice people who work there!! Dr. Gittleman is awesome!! Tells you what you need and doesn’t try to rip you off!! Thank you!
Tema T.
During a complimentary consult, the staff at OS was welcoming and polite, with smiles on their faces, from the moment I entered. From the front desk, to xray to consult with Dr Greg and Gina. They spoke with me in knowledgeable and professional terms that I could understand. And they explained more in depth without hesitation whenever necessary. The facility itself is in stellar condition and very clean/orderly. I was very impressed!
Response from the owner:Tema! What a pleasure it was meeting you. Thank you for sharing your experience and we are looking forward to seeing you again real soon! :)
Alicia S.
We had a great experience with OS! The front desk is organized and easy to work with. Every orthodontist we saw communicated exactly what happened during each appointment and what to expect moving forward. Highly recommend in every way!
Response from the owner:Thank you Alicia!
Danni Y.
My grandson loved his visit from start to finish with how nice everyone is how comfy and welcoming it felt and said the Dr. Has “rizz” he can’t wait to go back.
Response from the owner:Danni! You have us all laughing. Thanks so much for sharing your grandson's experience and pics! We are so excited to have you guys back in the office!!! Happy Holidays!
Andrew S.
Really glad we sought a 2nd opinion from OS. Less expensive, better payment options, better equipment, works well with our insurance, super friendly and accommodating.
Response from the owner:Hey Andrew! Thanks so much for coming to see us!! Keep being awesome!
nancy K.
Everyone in the office were great. My questions were answered. Someone always came out with Harper to explained her progress after each appointment.
