Dr. Quan is a great ortho. He treated my husband and brother in-law 15 years ago. I liked the results so much that I decided to use Dr. Quan. Luckily he's still around. He is very friendly and knowledgeable. His staff and facility is awesome. The price I paid for my braces is pretty comparable to other orthos that I consulted with before deciding to use Dr. Quan. I'm very happy with my decision to use him.
