Dr. Dallas is a general surgeon. He examined me, gave his view and we mutually discussed the surgery. I had some questions as there is much in the news about the procedure and history of people having post surgical problems. He was a bit light on really telling me how large the recuperation time would be. Made it seem like a piece of cake. After the surgery, his office did not have the records they needed to discuss just what happened during my surgery. They said the records were on another file at the surgical center. Overall, however, I am happy with the surgeon and his treatment of me. Unfortunately my wound did open a bit and bled two weeks after surgery and a suture was poking out of the wound. I went in and the n urse clipped it off but no one had warned that this could happen. it is a bit shocking to see a suture coming out of your wound. That said, I would return to him and recommend hi to others.
