About Joanna Pustilnik

Joanna is a Registered Dietitian, Diabetes Educator, certified intuitive eating counselor, certified health coach and personal trainer with a strong background in the treatment of eating disorders (anorexia, bulimia, binge eating disorder), weight management (including post bariatric surgery nutrition counseling), emotional eating, metabolic health and chronic disease, fertility and women's health (fertility, gestational diabetes, postnatal nutrition, and PCOS), sports nutrition, nutrition for mental health, digestive health (SIBO and IBS), healthy aging, plant-based nutrition, and sustainable eating. She received her Master’s in Nutrition Science from the University of Cincinnati before completing her dietetic training at Virginia Commonwealth University Medical Center in Richmond, VA.

Joanna is an empathetic and research-based clinician who individualizes all treatment protocols, focuses on food first, and takes a holistic approach that incorporates stress management, joyful movement, and lifestyle preferences. She utilizes cognitive behavioral therapy and acceptance and commitment therapy to help identify and modify disordered thinking around food and body image while supporting long term health.

Joanna's approach is based in mindfulness and the acknowledgment that we should enjoy and find pleasure in our food choices. She utilizes both intuitive eating and Health at Every Size to help connect clients to their natural hunger and find a comfortable and satisfying relationship with food and body. She believes in the power of self-care and proper nutrition to help restore our emotional and cognitive balance.

Joanna also has an extensive background in sports nutrition and wellness that includes working with crossfit and recreational athletes. She is a former college athlete, marathon runner, and avid weightlifter who values nutrition, fitness, and proper rest as the path to overall balance.
