Dr. Yu is my No. 1 dentist. My family and I visit him two times a year for cleaning and exam, he never asks you to do extra treatment if you do not need to. Plus, he spends time to sit with me and explain the treatment procedures with models and pictures in a simple manner. His office has the coolest x-ray machine that I have ever seen; it takes less than a minute, the x-ray of my teeth shows in the computer screen!! Professional, care and gentle!!
