Dr.Woo and the rest of the staff are awesome! Even though it is a bit difficult to talk when you’re getting your braces tightened, it was always great to catch up with them every 6 weeks! I love being braces-free now it was definitely worth it! P.S. Kathy and Nina were great when I needed to change an appointment!
