Philosophy of care | My aim is to provide quality care by educating you about your conditions so you feel more comfortable sharing your health concerns, have a better understanding of the treatment plan, and ultimately become a more active participant in your care. | Why I entered medicine | I entered medicine because I wanted to enter a field that combined my interest in science with the ability to work closely with people. Medicine provides this plus the opportunity to stay on the leading edge of technology and research while being a lifelong learner. | Community involvement | Locally, I am a member of the Pennsylvania Society of Gastroenterology. | Personal interests | I am an avid sports fan and season-ticket holder. I enjoy traveling to national parks and other new places, running, hiking, kayaking, listening to informative podcasts, and spending time with my family and dog.
