I researched several orthodontists in the San Mateo area and chose Dr. Chen because he's about doing what's right and reasonable, not about making money off you. He explained everything about the process and reasons behind it for me (He is also an associate professor at UCSF), he is very kind and great with patients, he listens to his patients, and he was able to fix my teeth at a reasonable price. Other orthodontists wanted to do surgery, have me wear head braces, etc. Dr. Chen accomplished it without all that. I highly, highly recommend him.
