Erica Zellner

I am a Connecticut–based clinical nutritionist with eight years of experience in functional nutrition and health. I enjoy working closely with all members, with a particular focus on fertility, pregnancy, postpartum care, and complex conditions such as mold-related illness. I earned my master’s degree in nutrition and integrative health from the Maryland University of Integrative Health and hold Certified Nutrition Specialist (CNS) and Licensed Dietitian-Nutritionist (LDN) credentials.

My Approach to Care
Empowerment! It’s within your control to be your happiest, healthiest, and most vibrant self. My focus is on well-being in every aspect of my members’ lives—mind, body, and spirit. I want you to confidently take control of each of these facets in healthful and fulfilling ways.
