Both of my daughters were patients here, and the experience was great. So there wasn't any hesitation as to where I would go when I decided to get braces 🙂 Staff and facility are super!!

The staff has helped me so much with my son who was terrified of coming to his visits. They were very relaxed and explained everything they were going to do. He just felt so comfortable with them. Dr. Mahaffey was wonderful as well!
