My son had an appointment at Orthodontic Specialists Doylestown with Dr. Greg Gittleman, and we had such a great experience. We were nervous going in, but everyone there was kind, welcoming, helpful, and very informative. They really put us at ease and made the whole visit go smoothly. We left feeling very happy with the care we received.

Thank you for trusting us with your son’s care! We look forward to being part of his orthodontic journey!
Laurie C.
Went to the Souderton location for a consultation for my oldest son. Clean office and friendly staff! Brought my middle son along and both boys enjoyed juice boxes and both left with prizes :) Thoroughly explained the process and payment options for his treatment. Highly recommend! Update in 2026: My oldest son is still a patient there, so my middle son was very excited for it to be his turn! He even got to enjoy a popsicle while we were there. Appointments are easy to schedule (we’ve had to schedule a few emergency ones). 10/10 recommend!
Response from the owner:Hi Laurie! It was a pleasure having you and your boys in our Souderton location. Looking forward to seeing you all again for some more prizes and endless juice boxes! :)

The office staff instantly made us feel welcome. Thank you Lauren and Jen. The upgrades to the building since the last orthodontist are impressive and bright and clean. The pictures on the walls of patients and their beautiful smiles showed us the quality of their work. The assistant, Sam, made my daughter feel comfortable and settled as she had X-rays completed.
Response from the owner:Hi Dana! We're delighted to hear that you and your daughter felt welcomed from the moment you arrived. We'll be sure to share your kind words with Lauren, Jen, and Sam...they'll be so happy to know they made such a positive impression. See you soon!

The office runs smoothly and efficiently. There is a Keurig with assorted coffees and teas to sip while you wait for your children. The cost of the orthodontist is very reasonable. Staff is friendly and kind. The practice also supports local non-profits.
Response from the owner:Roberta! Thank you so much for sharing your experience. We love that you enjoy coming to see us!
Jacquelyn D.
Brought my 2 children in for a consultation and the staff was extremely helpful, friendly, and very informative. I always feel like most places try to talk you into things that aren’t really needed just to make money. Not this office, they were very honest and there was zero pressure.

Friendly, efficient, professional, clean.. nothing but amazing things to say about Dr. Justin and staff! We consulted with various orthodontists in and around Center Valley and ultimately are pleased with our choice to send our kids (and now myself with aligners) to OS!
Response from the owner:Sherry and the Graham Family! We’re honored you chose OS after exploring several options in the area. It means so much to hear that you’ve had such a positive experience and we’re excited to now be part of your aligner journey as well! We truly appreciate your support and look forward to continuing to care for your family’s smiles.
Lauren Z.

Response from the owner:We appreciate you trusting us with your sons smile, Lauren! We look forward to seeing you again soon!
Candace Y.
Our son misplaced his bottom retainer and is home from college and needed a replacement. We had a great experience from the first call to our visit a few days later. Everyone in the office is friendly and knowledgeable and the price was very reasonable. Highly recommend this orthodontic practice!
Response from the owner:Hey there! Thank you for your kind review! We're so glad we could help your son get a replacement retainer. It's wonderful to hear that your experience was positive from the very first phone call through your office visit. Our team strives to provide friendly, knowledgeable care and make the process as convenient as possible for our patients and their families. We truly appreciate your recommendation and look forward to being here whenever you need us!

Great place!! The whole environment and all the staff are very welcoming . Highly recommend !!!!
Response from the owner:Thanks for taking the time to share your feedback, Cynthia!
Irvin E.
Great staff and great skills. Really have no complaints, the scans take 2 minutes. Had a problem with my wire popping out cause of what I ate on a Saturday and was stressing about how I would fit this all into my schedule. The doctor sent me a message same night on how I could fix the issue by myself with a simple fix. Never had the issue again anyways. Thanks!
Response from the owner:Hey Irvin! We know how busy life gets, so we always try to provide quick, convenient care and easy solutions for those little emergencies. We’re thrilled the quick fix worked for you and that you never had the issue again. We look forward to seeing you at your next visit!

This practice is populated with the nicest people. They are so kind and patient with me and my dental worries! Dr Gittleman is the nicest guy who wants to do the best for his patients. It’s a little crazy how sweet they are. Go and see for yourself!
Response from the owner:Hey Debra! Thank you so much for your wonderful review! Dr. Gittleman and our entire staff are committed to providing compassionate, personalized care, and we're grateful for the trust you've placed in us. Thank you for your recommendation!
