About Me
My interest in digestive and gastrointestinal disease began as a medical student and only grew over the subsequent years. I have trained at Duke Health within the field of gastroenterology and have a focus in advanced endoscopic techniques and pancreatic and biliary disorders, benign and malignant conditions. I enjoy providing care for all patients within the clinical setting as well as at the time of procedure in order to ensure delivery of the best quality care. I hope to provide a partnership with my patients by getting to know each individual and their family and by serving as an advocate for their care. Last, but not least, I enjoy working with and learning from all of my colleagues at Duke Health. Each member of the Duke team enriches my day at work and also provide continuous opportunities for learning.

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.
Training and Education
Clinical Focus and Research
