Orthodontist specialist has treated me for over two years and every time I come for an appointment I never fear what will happen. They make me feel comfortable and never judged. I appreciate how they boost my energy and make my day, leaving with a bright, big, smile.

Jessica E.
Went here growing up now have my kids here! Love the environment and staff so much! Welcoming and personal!
Response from the owner:Jessica! Thank you for trusting us and coming back. We appreciate you and your family!
Christina L.
Went to Orthodontic Specialists after a consultation through our linked dentist/orthodontist with an odd plan of action. I agreed with the plan at OS so much more and we just completed phase 2 with my oldest. I always recommend Orthodontic Specialists and am so happy to bring my children there. The staff is always so welcoming and friendly. Best Orthodontist Around!!! ⭐⭐⭐⭐⭐
Response from the owner:Christina! We’re so glad to hear that you felt confident in the treatment plan and had a great experience. It truly means a lot to us that you recommend our Souderton office and feel comfortable bringing your children here. Our team works hard to create a welcoming and positive environment, and we’re happy that it shows. We appreciate you being part of our orthodontic family!
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!
Tauni M.
I have brought all 3 of my children here and we have had an amazing experience. My youngest son was permanently missing front teeth and after diligent and dedicated work, they pulled all the teeth forward and filled the space, saving him implants. The pricing was excellent and they feel like family now.
Response from the owner:Thank you, Tauni! We have loved having all 3 of your children at our Doylestown office. We appreciate your trust and look forward to continuing to care for your family’s smiles!
Stacy M.
We have had an amazing entire team at Orthodontic Specialists! From the very first consultation to getting braces on all of my kids, everything has been handled with professionalism, care, and genuine kindness.
The staff is always welcoming, patient, and great at putting my kids at ease, which makes a huge difference. The orthodontist takes the time to explain everything clearly, answer questions, and make sure we feel comfortable every step of the way. Appointments are efficient, and the office is always clean and well-organized.
Most importantly, the results have been fantastic—my kids’ smiles look incredible, and their confidence has grown so much because of it.
I truly couldn’t ask for a better experience and highly recommend Orthodontic Specialists to any family looking for top-notch orthodontic care!
Response from the owner:Wow, thank you Stacy! We are honored to have been part of your family’s orthodontic journey. It means the world to us to hear that your children felt comfortable and at ease, and that our team’s care, communication, and professionalism made a positive impact throughout the process.
Alyssa M.

Response from the owner:Hi Alyssa! Thanks for the wonderful review! We take pride in creating a welcoming and clean environment for our patients. We’re excited for you to start your clear aligner journey with us in a few weeks at our Souderton location!

This orthodontist is very clean, bathrooms are very clean, they have refreshments for you while you wait.

Response from the owner:Thanks for taking the time to share your experience at our office, Kellsey!
Charleen H.
We had a wonderful experience at our first visit. Everyone was very welcoming and helpful. My daughter was very apprehensive before attending her first appointment at the facility. The staff put her mind at ease as well as mine and took the time to explain how we would be proceeding with her orthodontic treatment. She is even excited about getting braces. I am so thankful that we found this practice.

We are so grateful for the staff at OS. My son also just finished up with braces, and I can't believe how great his new smile is. Loved the weekly scans. What a great technology that was available to us during this journey. It was nice to have feedback and watching the transformation was amazing!!!!
Response from the owner:Charleen thank you for the kind review! We are glad you found us too.
Darcy H.
Made my daughter feel right at home during her first ever consultation. Very welcoming & a great vibe for even an anxious kid like mine.
Response from the owner:We appreciate it Darcy! It was so great meeting you both!
emily M.

Shawna E.
Dr. Justin and his entire team go above and beyond! Highly recommend! Dr. Justin was extremely helpful, patient and personable. The whole experience was friendly and welcoming each time. Everyone involved cared so deeply! Thank you to the entire team for all that you do! ❤️
Response from the owner:Hey Shawna! Our team takes great pride in making sure each person feels heard, comfortable, and confident in their treatment, and we’re so glad that came through. Thank you for trusting us with your smile and for being such a valued part of our office family!
James M.
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!
Lourdes B.
My first visit to this office and it went really well.The people are so friendly.The doctors are very professional I'm excited to start my journey
Response from the owner:We are just as excited, Lourdes! See you soon doll!
Emily B.
Dr. Justin and his entire team were truly exceptional today. Even though my younger daughter wasn’t being treated, Maddie went out of her way to play with her and kept both of my girls happily distracted so I could focus and talk with Dr. Justin. He was incredibly informative, kind, and patient, he answered every question thoroughly and made me feel completely comfortable and confident. Their professionalism and genuine care from the whole team really stood out, and it was such a wonderful experience overall.
Response from the owner:Maddie truly is the best! We are so thankful for our team and happy you and your family enjoy your time at the office! :)
Dawn R.
