Will Bulsiewicz

I’m a triple board-certified gastroenterologist and lifestyle medicine physician, internationally recognized gut health expert, and 3-time New York Times bestselling author of Fiber Fueled, Fiber Fueled Cookbook, and Plant Powered Plus. I earned my medical degree from Georgetown University and a Master’s in Clinical Investigation from Northwestern University, where I also completed my internal medicine residency. I served as chief medical resident at Northwestern and chief gastroenterology fellow at the University of North Carolina, earning top clinical honors in both programs, and completed an NIH-funded fellowship in epidemiology. I’ve authored more than 25 scientific publications with over 5,000 citations and have delivered keynotes and briefings for audiences ranging from Congress and the USDA to major medical conferences and the NFL Alumni. My books have sold more than 500,000 copies worldwide and are translated into 20 languages. In addition to my clinical and research work, I speak to professional and corporate audiences on the science of gut health, nutrition, and long-term wellbeing, translating complex research into practical, evidence-based strategies. I’m the founder of The Gut & Microbiome Center for Excellence, a telemedicine practice focused on personalized, gut-oriented care, and the co-founder and co-CEO of 38TERA, where I work with nutrition scientist Simon Hill to develop microbiome-supportive supplements grounded in transparency, safety, and scientific integrity. I live in Charleston, South Carolina with my wife and four children and share free educational resources at www.theguthealthmd.com. For bookings contact christina@theguthealthmd.com
