Dr O'Malley seemed like a matter of fact person. He didn't discuss risk or really anything it was more like going thru the motion. He wasn't rude just I guess no bed side manner

Doctor was condescending and rude. He questioned my concerns as if they were frivolous. Worst bedside manner I've ever experienced. Dr. Had a very Negative attitude and spoke to my husband instead of talking directly to me, the patient. I would never recommend him to anyone.

I know many people who have been cared for and worked with Dr. O'MALLEY and he comes highly recommended. I was told in advance that he doesn't have the most gentle bedside manor and I expect that to a degree. I was still a bit shocked by how the brief encounter was and how very impersonal it all felt. I thought it would have been a discussion with him to allow my questions to be answered organically. However, it was just a handful of medical questions, a super brief medical exam, mention of the incisions and drain... It was easily the shortest apt I've have with any provider in years - which did leave me a bit troubled seeing as this medical relationship if much more impactful and sensitive. I was told to expect this but was still a bit shocked. It hasn't swayed my decision at all but I wish the encouter had lasted longer and he had taken some time with me.
