Dr. Chao and his staff are very professional and courteous. He is to the best of my knowledge, up-to-date with all of the current therapy options and can offer a wide range of treatments. He personally takes the time to consult you on your options with or without insurance. However, he is rather expensive, and at the same time, he is not a member of any dental insurance provider list that I know of. If you're hoping to use your dental insurance with him, you might have to pay more of a copay. Otherwise, he is a knowledgeable dentist that is very professional and thorough.
