As a new patient here with Dr. Robert Orr, at Phoenix Medical Group, I found the process fairly quick and simple. Check in was pretty east too.
I was called in ahead of schedule, but the doctor was about 20 minutes past the appointed schedule time. And based on previous experience here with my mother, this is typical. The MA and the doctor are pleasant and quite nice. The front desk staff vary, but overall are okay (they are sometimes harried by a bit too much going on without enough people to take care of it I think).
