Jessica Nighswander, RD

Hi, I'm Jessica Nighswander, a registered dietitian with a passion for helping individuals discover a sustainable and personalized approach to health—without restrictive diets. As an anti-diet dietitian, I work with my clients to cultivate balanced eating habits that support long-term wellness, embracing the uniqueness of each person’s lifestyle, needs, and preferences.

My areas of speciality include gastrointestinal disorders, oncology nutrition, and nutrition support through enteral feedings, including whole food blenderized tube feedings. I am committed to helping clients navigate complex nutrition challenges, whether you're managing digestive issues, undergoing or recovering from cancer treatment, require nutrition support through tube feedings, or just want to simply improve your nutrition practice. I bring a whole-food, nutrient-dense approach to care and I love sharing tips and recipes that help my clients nourish their bodies in a way that is both enjoyable and practical.

I earned my degree in Nutrition from the University of Massachusetts at Amherst and completed my dietetic internship at the University of Delaware. I also hold an Integrative and Functional Nutrition Certification (IFNCP), which allows me to integrate a holistic approach into my practice, offering a more comprehensive view of health and wellness.

In addition to my private practice, I also work inpatient at Mass General Brigham at Cooley Dickinson Hospital and Cancer Center where I work with individuals in the acute care setting.

When I’m not working with clients, I love spending time with my husband, son, and dog.You will find me outside as much as possible—whether I'm tending to my vegetable and flower gardens, cycling, or enjoying walks in the woods. Being in nature grounds me and inspires my approach to food—simple, nourishing, and full of life.

If you're looking for a compassionate, knowledgeable dietitian who can help you build a lasting, sustainable approach to health, I’d love to work with you. Together, we’ll create a personalized plan that feels just right for you and supports your unique health journey.
