Dr. McMorrow is one of the few doctors I have visited recently that is will to spend time with you and answer all of you questions. He performed more of a physical on me than I got from my GP recently. When I asked him about any liver issues he said stay put and I will go look at your recent blood work. When he cam back he said all looked good, which make me very comfortable. When I told him I was concerned on weight gain he has recommend a dietitian to work with me.
