Overview
I’m a nurse practitioner specializing in gastroenterology, with a clinical focus on inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis. I’m especially passionate about building strong, lasting relationships with my patients and creating space for open, collaborative conversations. Shared decision-making is central to my approach, and I strive to ensure every patient feels informed, supported, and empowered in their care. Originally from New York City, I spent several years living and working in Boston before making North Carolina my home. Outside of work, I love exploring new cities, trying different foods, and spending time with friends and family.
