Appointment time mixed up, I received a call to confirm at the same time that I had written in my calendar. Front desk told me that I had to sit in a overcrowded waiting room to reschedule. I am pleased with the Dr. , but the staff makes or breaks an office. By the way the same receptionist told everyone ahead of me that the doctors were running 45 minutes late. I was 20 minutes past their "wrong " appointment time. 10 of which I waited in the hall behind 5 people to check in. Just rude!!!
