Overview
I am a gastroenterologist and gastrointestinal cancer geneticist. I diagnose and treat a range of gastrointestinal conditions with endoscopy and colonoscopy. I also perform colonoscopy for colorectal cancer screening. As a member of the Hereditary Cancer Clinic, I am interested in helping patients assess their risk for gastrointestinal cancers. I work closely with genetic counselors to review family history of cancer, detailed health history, environmental exposures, and genetic testing results. I then integrate these findings to provide a personalized cancer risk assessment for each patient. My goal is to guide patients through treatment and screening programs to reduce their risk of cancer.

Duke Gastroenterology Raleigh Endoscopy
I became a doctor because of my lifelong desire to help people. In fact, when asked as a young child to draw a picture of what I wanted to be when I grew up, I drew a picture of myself with a stethoscope. Gastroenterology appealed to me because it involves complaints that almost everyone experiences at some point, and helping people feel better is very gratifying. In my practice, I see adults with common digestive tract issues, including heartburn, abdominal pain and changes in bowel habits, as well as a focus in seeing patients with inflammatory bowel disease (ulcerative colitis and Crohn's disease). I believe spending the time to get a detailed history from each patient is valuable, not only for diagnosing and successfully treating or managing these conditions but also for establishing an open, comfortable physician-patient relationship.
