Tip: don't visit on a weekend. Quite a backlog when I arrived. The doc was fine but the front desk seemed confused about my check-in details and processing my insurance. They said they don't ordinarily use ZocDoc for booking. If you live in Uptown and need to see a doc on the fly, this is a convenient place w/ weekend hours.
I was actually seen by a different doctor here at Doctors Express, but the nurse and doctor were great, both efficient and friendly, I arrived 30 minutes early and they actually got me in and on my way with a prescription only 5 minutes after my original appointment time.
Good.
