Eric L.
Wonderful staff that take a personal interest in their patients. Clean and professional office with a personal touch. Starting with the 3rd child getting braces now, great results with the first two.
Darlene G.
We had a wonderful first experience! The entire staff was friendly, welcoming, professional, and efficient. They were incredibly understanding, respectful, and communicative throughout the visit, making sure we felt comfortable and informed every step of the way. Everyone was kind and took the time to answer questions without making us feel rushed. It’s clear they truly care about their patients and creating a positive experience. We are so happy we chose this orthodontist and would highly recommend them to anyone looking for a welcoming, professional team!
Bike P.
We absolutely love Dr. Silvestre and the entire OS team! Everyone is always so pleasant, welcoming, and professional. They greet you with a smile every single time, are consistently on time, and make every visit such a positive experience. Dr. Silvestre is amazing—knowledgeable, caring, and truly wonderful with his patients. He takes the time to make sure everything is explained and that you feel comfortable and confident throughout the treatment process. As a mom, it means so much to know that Feliks is in such great hands. The combination of outstanding care, attention to detail, and a genuinely friendly atmosphere makes all the difference. You can tell that this team truly cares about their patients, not just their smiles. We couldn’t be happier with our experience and would highly recommend Dr. Silvestre and his team to anyone looking for exceptional orthodontic care! 🦷😁

Thank you guys for calming my daughters nerves and we can’t wait to get started soon with treatment!!

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 just had our consult with Dr. Gittleman. He and his entire team were warm, welcoming, and family centered. Dr. Gittleman gave a thorough consultation and was willing to answer any questions we had. We look forward to working with the team in the coming year(s) for our son’s orthodontic care!
Giorgi K.
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.
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!
Ryan A.
Went for a consultation for my daughter. The whole staff was very friendly and welcoming from the moment we walked in the door. Dr. G was great and took the time to explain everything to us. Highly recommend!
Dana H.
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.
