We had a great experience with Dr. Silvestre and his entire staff! Everyone was extremely friendly, welcoming, and professional from the moment we walked in. The orthodontic office is very clean, modern, and comfortable. Dr. Silvestre and his team took the time to explain everything clearly and made sure we understood the entire process and what to expect. We never felt rushed, and everyone made us feel completely comfortable. I highly recommend Dr. Silvestre and his staff to anyone looking for a professional, knowledgeable, and caring orthodontic team. Great experience all around!

My son had an appointment at Orthodontic Specialists Doylestown with Dr. Greg Gittleman, and we had such a great experience.

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!
