I’m a general gastroenterologist and treat a wide range of GI problems, but my area of specialty is in esophageal disorders. I see patients who may have swallowing disorders, hard-to-control acid reflux disease, or disorders or problems with the muscles of their esophagus. I also see patients with Barrett's esophagus, which is a gastroesophageal reflux disease where the lining of the esophagus may change over long periods of time. We need to treat it to prevent patients from getting esophageal cancer. It is important to establish a level of trust and have compassion for patients, making sure they feel that I’m completely invested in what’s important for them, doing everything to get to the right answers of what’s causing their symptoms, and coming up with a plan that works best to treat their problem.

I am thrilled to return to Duke Health after my recent retirement to provide much-needed part-time endoscopy services and improve access to colon cancer screening and surveillance. I first came to Duke from Kansas in 1989 and loved the pine trees and people so much that I never went back. I was the first female gastroenterologist (and 20 weeks pregnant) when I started private practice in Raleigh in 1994. After nearly 30 years of uninterrupted service to my beloved patients in central North Carolina, I retired in January 2024. It was difficult to give up my passion for gastroenterology, colonoscopy, and patient interaction. I am eager to return with a schedule that allows me to travel more with my husband. I enjoy meeting patients and easing their anxiety through rapport and detailed explanations. A little humor and hand-holding also help. I love safely removing large polyps.I have two grown children; my daughter is a physical rehabilitation PA in RDU, and my son is a game quality control specialist in Austin, Texas.

Many years ago, I came across a quote from Mahatma Gandhi that said, “The best way to find yourself is to lose yourself in the service of others”.

With every individual and their families, I make sure that they appreciate my understanding of how their health issues provide them with new stresses that may leave them confused and scared. As a result, I pride myself on reassuring my patients and making sure that by the time they leave their clinic visit they know that I have their best interests at heart.
