I’ve been going to Dr. DeSimone and DeSimone Orthodontics for almost a decade, and I truly can’t say enough good things about my experience. I had a very difficult case, and throughout the entire process, Dr. DeSimone was incredibly thoughtful and skilled in finding the best approach for me. I was able to use Invisalign for several years with expertly placed attachments that helped me avoid having to wear more cumbersome gear or traditional braces, which I really appreciated. Even years later, the level of care has remained just as great. I recently came back because I needed to have a retainer remade, and they were able to take my impressions and have a new retainer ready for me that same day. Both of my siblings have also been patients of Dr. DeSimone and have had similarly great experiences, so our family has been coming here for years. Dr. DeSimone and the entire staff have always been incredibly friendly, accommodating, and genuinely great to work with. I would absolutely recommend DeSimone Orthodontics to anyone looking for an orthodontist they can trust.

I have been going to Dr.DeSimone since I was 15 years old. She did a wonderful job with my invisalign journey when I was a teenager, and absolutely did not disappoint as an adult when I returned for additional treatment. They are a kind and welcoming staff who truly wants the best for their clients. If you live in the Pennington area, I 10/10 recommend Dr.DeSimone and Kelly orthodontics!

Two years of head gear and five years of braces I am loosing my front four teeth. Every endodontist and dentist I’ve seen has confirmed my teeth had just been through too much. I am now facing implants. DO NOT JUST TRUST DOCTORS OR DENTISTS DO YOUR RESEARCH!

Both of my sons had braces with Dr. DeSimone and had two fantastic experiences! I’m a stickler for customer service and the entire staff is incredible - consistently friendly, knowledgeable and professional. They’ve created a warm environment for patients and their families - something that was very important for me when looking for an orthodontist in addition to a high standard of treatment. Can’t recommend them more highly.
