I went to Dr. May for Invisalign, a chipped tooth, a few fillings, and whitening. Everything has exceeded my expectations and I have not had one complaint in the 8 years of going to him. His staff is very friendly and accomodating. Dr. May is a pleasure to see and even fixed a chipped tooth for me on a weekend. I've referred many friends to him and I truly believe he's the best dentist in the Bay Area.
