Patient Comments (1)
in Hagerstown |
Dr. O'Connor was unfriendly, rude and impolite to my elderly father, my husband and me. He had a superior attitude toward us and was not forthcoming to the questions we had about my father's treatment. He seemed to resent any inquiries we had. When he finished examining my father, he told us to make an appointment at the front desk and didn't even say goodbye. He has no bedside manner and is cold and sarcastic. My father should have been admitted to the hospital immediately, but was sent home.
