Corwin Nixon is quick to say you will need to reschedule if you are not on time, but they are not respectful of their patients' time at all. My apt was 10:00, I arrived at 9:57, the receptionist attempted to cancel my appointment, because she said I was late. I informed her I was not late, but I waited one hour there and had not seen the Nurse Practitioner, they really need to practice what they preach!!
