Dr. Lai is great, smart, personable. I wouldn't go to any other dentist. He also gives very good referrals where necessary (e.g. I had a root canal and the surgeon was excellent too). And you get a nice goody bag with each cleaning (toothbrush and paste, floss and some extras).
His front office staff, however, leaves a lot to be desired (bad "you're lucky I'm helping you right now" attitude, tattoos, low cut tops, generally very strange for such a professional office otherwise).
