MEGHAN DONNELLY, MS, RDN, CSDH

My name is Meghan, and I am a registered dietitian and Board Certified Specialist in Digestive Health (CSDH) based in New York City. I specialize in gastrointestinal nutrition, helping individuals with celiac disease, IBS, SIBO, reflux, and other digestive disorders find long-term relief and confidence with food.

I take a weight-inclusive, food-first approach to care, focusing on sustainable strategies that improve gut health, reduce symptoms, and support a positive relationship with food. My work centers on translating complex GI science into clear, practical guidance that helps people feel better in their daily lives.

I hold a Master of Science in Nutrition & Dietetics from New York University.
