If somebody is going to make a huge hole in my body and remove a part of my lung and some lymph nodes, I want somebody who has done it many times before. Dr. Mammana has done thousands of these surgeries. He knows what to expect. He knows how to do it. I had this surgery 2 1/2 months ago, and it was very successful. There have been no surprises. I was back at work after 9 weeks. He did a great job in the surgery and a great job of explaining things to me and my wife. I would recommend him to anybody.
