• Dr. Kennedy is certified by the American Board of Colon and Rectal Surgery and by the American Board of Surgery. In addition, he is a Fellow of the American College of Surgeons and a Fellow of the American Society of Colon and Rectal Surgery. Kennedy’s main interest is in laparoscopic approaches to complex colorectal disease. He has experience with all advanced laparoscopic and minimally invasive approaches including single-incision laparoscopy and robotic surgery. His clinical areas of expertise include colon cancer, rectal cancer, inflammatory bowel disease, benign conditions of colon, rectum, and anus, and endoscopic treatment of colonic disease.

    Dr. Kennedy was born and raised in Montana and is a graduate of the University of Washington School of Medicine in Seattle. He earned his doctorate in cancer biology at the University of Wisconsin School of Medicine and Public Health, where he also completed his general surgery residency in 2006. Dr. Kennedy then completed his colon and rectal surgery fellowship at the Mayo Clinic in Rochester, Minn., in 2007.

    Dr. Kennedy’s research efforts are focused on chemoprevention of colon and rectal cancer. His funded laboratory uses genetic models to better understand how chemicals prevent tumor formation and what genetic pathways are responsible for their effects. The ultimate goal is to identify targeted agents that are better tolerated by patients in hopes of preventing colon and rectal cancer.
