About Me
My area of interest is inflammatory bowel diseases (IBD) such as Crohn’s disease and ulcerative colitis. I also participate in clinical research to help evaluate new medications or products for use in IBD. These trials enable us to offer cutting-edge treatments for patients with Crohn’s and ulcerative colitis. I came to Duke as an intern almost 30 years ago and liked it so much I never left. I enjoy the relationships I have developed with my patients, some of whom I have treated for 15-20 years. I have watched many of them graduate from college, marry and have children of their own. I try to treat my patients as I would want a member of my family to be treated, and it is important to me that every patient understands that we are partners and need to work together as a team. When I am not at work, I enjoy going out to dinner or cooking with friends, working on my house, landscaping, and reading.

Ratings and Reviews
The ratings and reviews are based on patient responses to the overall provider rating question from the survey. The question reads: “Using any number from 0 to 10, where 0 is the worst provider possible and 10 is the best provider possible, what number would you use to rate this provider?” Responses are converted to a 5-point rating system and applied consistently to all providers. Learn more about our survey process. Patients who see some types of providers receive a different version of the patient satisfaction survey. Those results are not available on DukeHealth.org.

Clinical Focus and Research
My area of research interest is inflammatory bowel disease. I conduct clinical trials for new therapies for Crohn’s disease and ulcerative colitis. Many of these trials enable us to provide access for our patients to cutting-edge treatments, searching for drugs or other therapies that might put the disease into remission and improve quality of life.
