Sherri Clerk, RDN, LD, MBA

Sherri is a registered (RDN) and licensed dietitian (LD) with a passion for wellness, using food as fuel to nourish our bodies.  In a world bombarded with nutrition advice and information, she strives to bring credible, science-based recommendations to our clients in a positive, non restrictive way.  She focuses on what is missing instead of what we need to take away. 

After earning her BS in Dietetics from the University of Kentucky and completing a dietetic internship at Vanderbilt University, she spent a decade working with the largest nutrition support team in the country.  Under the guidance of gastroenterologists specializing in nutrition, she implemented a comprehensive approach to weight loss in outpatient settings.  Her MBA then led her to opportunities in the food industry, where she contributed nutrition content and collaborated with research and development as well as culinary teams at companies like McCain Foods, Hormel Healthlabs, and High Liner Foods. She currently consults for the Global Seafood Alliance (GSA) where she helps to promote increased consumption of responsibly sourced seafood and works per diem as a dietitian in a physician led interdisciplinary team, Lifestyles by Noor.  Her areas of focus are weight management and lifestyle medicine.  She brings her passion for nutrition, fitness and meal planning to help you meet your personal goals.
