Pediatric Nutritionist in New Jersey


Your child's everyday diet plays an important role in brain function. At NJPNI, our pediatric nutritionist can help craft a diet that maximizes brain function. Individualized diet plans that are backed by evidence-based research may also help to alleviate symptoms of ADHD, headaches, autism, and a number of other neurological conditions in many patients.

Why see our Pediatric Nutritionist?

A Pediatric Dietitian, also called a Pediatric Nutritionist, offers a child-centered approach specializing in dietary needs of growing infants and children. Heather will perform comprehensive assessments about your child's health and growth, and use that information to create a customized plan to support your child's nutrition and development.

Helping your child every step of the way

Heather will share meal plans and recipes, give you tips and techniques; and help your child thrive through the transformative power of food and nutrition.
