Dr. Sun was highly recommended to us by our daughters surgeom. His treatment started 18 months ago, when he started our daughter had very crooked teeth due to being born with a cleft palate. Within a few months the difference was amazing, she is getting ready to have them taken off soon. She hasnt had to keep them as long as we originally planned, hzes done an amazing job. Shes never missed an appointment nor has she ever feared or not wanted to go. I will take any of my other kids that need braces only to him!
