Dr. Mai is the best. You get her undivided attention when you see her, and she knows EVERYTHING (or so it seems). She listens and she's willing to work with you on whatever is bothering you, whatever you're worrying about. And if something is not a big deal, or is a waste of your time/money, she'll say so. She also knows who the best specialists are and you can be confident about her referrals. Yes, you pay an annual concierge fee to be her patient, but I think it's worth it.
Also, after reading a couple reviews here, I want to say that yes, I have had to sit in in her waiting room for a while before, but not since she went concierge a couple years ago. And Dr. Mai has a sense of humor. So I can see being deathly sick with the flu and thinking it's NOT funny (or even OK) when your doctor says something like "join the club." But honestly I think it's a matter of humor and personality. She is not a jerk. I actually take comfort (and have a laugh) when I think I'm dying and someone tells me I've got some common illness, just like everyone else, and that I will survive.
