I have been going to Dr. Ngo for a long time now and think she's a great dentist. She and her staff take the time to answer all of my questions as well as make me feel comfortable when I come see her. They're very knowledgeable and friendly.....A+ for customer service. She's recently moved to a new dental office. The office looks very nice and clean, and it's a very convenient location (Westheimer and Dunvale). I highly recommend this dentist.
