Mary Kate Fuller, MS, CNS, LDN, CHHP

Integrative Clinical Nutritionist

Mary Kate Fuller is a licensed functional nutritionist and integrative health practitioner who helps clients get to the root of their health concerns using a clinically grounded, personalized approach. With a deep passion for healing the body through food, lifestyle, and targeted supplementation, she works collaboratively with each individual to uncover and address the physical, emotional, and environmental factors contributing to their symptoms.

Mary Kate specializes in gut health and digestive disorders, hormone balance (including preconception, fertility, and pregnancy nutrition), and the vital connection between nutrition and mental health. She is especially passionate about supporting individuals dealing with anxiety, burnout, fatigue, infertility, and chronic digestive issues like IBS, SIBO, and GERD.

In a world full of conflicting nutrition advice, Mary Kate’s approach centers on clarity, compassion, and science. She recognizes that healing is never one-size-fits-all—your personal needs are shaped by genetics, lifestyle, medications, trauma, digestive capacity, and more. Her goal is to help you feel empowered and deeply supported on your health journey.

Mary Kate believes that true nutrition is not about guilt or restriction—it’s about self-love, self-awareness, and intentionally nourishing your body and mind. Together, she’ll help you build sustainable habits that support long-term health, vitality, and resilience.

She holds a Bachelor's degree in Psychology from Temple University and a Master’s degree in Clinical Nutrition and Integrative Health from Maryland University of Integrative Health. She is a Board-Certified Nutrition Specialist (CNS), a Licensed Dietitian Nutritionist (LDN), and a Certified Holistic Health Practitioner.

With over 13 years of experience in the integrative and functional nutrition space, Mary Kate brings warmth, expertise, and a whole-person perspective to every session.
