About Me

Often there are many treatment options for patients with diseases of the esophagus. I prioritize patient education because I believe that the better you understand your individual medical problem, the better I can take care of you. My philosophy is to work with you as a team to determine which treatment option is best for you, and then provide you with superior surgical care in the least invasive way possible.
