I have been going to Dr. O'Connor for many years. He spends a lot of time with his patients when you have an appointment. He explains everything in detail so it is understandable. He is extremely knowledgeable and is not afraid to advise you as to what all of your options are.

Calling Dr. O'Connor during weekend hours with an acute issue was problematic. He acted annoyed that he was paged. I have been a patient for many years and until recently never needed to contact him during off hours, until recently. He acted like I was bothering him . I work in the health care field- I know how busy Doctors are but the treatment I got was unacceptable..I'm so disappointed because I really liked Dr. O'Connor and thought he would be there for me.

Dr. O'Connor always listens to my laundry list of complaints and addresses all of them during a visit.
