    I have been seeing Dr Stefaniwsky for almost 20 years as my primary care physician and gastroenterologist. My parents have been patients of his as well for longer than I have, and we all agree he is a fantastic doctor who treats his patients with respect and spends time listening to concerns and offering medical advice and solutions.
