Dr Ellis has always seemed very concerned about my well being. I am very satisfied with what he has done for me. I feel he saved my life. No other dr. Would do the surgery that he did because of high risk. But he was willing to do anything to help me feel better.

Dr. Ellis is very thorough and is more than willing to spend as much time as it takes to answer questions, address concerns and recommend treatment. Even so (and certainly not a reflection on Dr. Ellis), there are things about my condition that I still do not grasp.
