Care Philosophy
I consider the practice of medicine to be a privilege and honor. I strive to be the best gastroenterologist I can be by caring for each patient as I would a member of my own family. My mission is to use my training in gastroenterology and therapeutic endoscopy to improve the lives of my patients. Outside of work, I enjoy spending time with my wife and three sons, often somewhere outdoors.
