Emily Gargis

Emily’s interest for nutrition and advocacy for eating disorder recovery developed out of her own recovery journey toward a positive relationship with food and body image. Her energy and support for Health At Every Size (HAES) and Intuitive Eating expanded even further after navigating her diagnosis of PCOS. After earning her Bachelor’s and Master’s degrees from the University of Memphis, she began her career as a Registered Dietitian in eating disorder nutrition therapy with Simply Nutrition. Later, she began working part time as a clinical dietitian in both the oncology and surgical units.

Emily is a firm believer in that all foods fit and that food is not of moral value (no “good” or “bad” foods), but for nourishment and enjoyment.

As a military spouse enjoying the travel it brings every couple years, Emily is currently living in Washington State and is seeing clients virtually! When she isn’t working, you can find Emily reading, exploring nature trails with her husband and pup (Brie), planning her next social outing, or tending to her plants.

Emily enjoys working with adolescents, college students, and adults. Her areas of focus include: Disordered Eating/Eating Disorder Recovery, Intuitive Eating, PCOS, Nutrition Therapy for General Wellness & Prevention, and Meal/Snack Planning.
