Dr. Leong is very good with children and easy to talk to. The office staff and assistants are very friendly. My son had many treatments so far and had some problems. The fillings came off less than one month even he was sleep during treatment - expensive procedures. We were very disapointed. Dr. Leong's charactores are so nice, but I can not trust his skills of work.... I only recommend if your child dones't have to have complicated treatment. For regular check-ups, your children love the doctor and his staff.
