Eileen Pierro, MEd, RD, LD

Eileen Pierro is the Owner of Nutrition Therapy, LLC in Portsmouth, NH.

As a registered dietitian nutritionist with over 20 years of experience in the field, it is my passion to support the health of children and adolescents through healthy eating and prevention of disordered relationships with food. 

The physicians, nurse practitioners, therapists, and families I’ve collaborated with have been relieved to have someone to refer to who is an expert in food and nutrition that can help with menu planning, snack ideas, and being of emotional support through the challenge of having a family member with an eating disorder.   

I have had the privilege to work with people from all walks of life, ages, cultural/food traditions and financial backgrounds. My love of food and cooking, my knowledge of food preparation, food and nutrition science, pediatric nutrition, and psychology helps me educate and relate to patients in a unique and positive way. I feel very fortunate to have the opportunity to help people improve their quality of life with my work.
