I had three office visits with this physician, never waited less than 45 minutes after my scheduled appointment to see him or his PA. He always had an reason, always some minor emergency. Had hand surgery scheduled for over a month, they called me the night before and changed it from 1PM to 6PM.  I cancelled and have not been back. Will use a physician with more respect for his patients.
