Our Founder & Formulator: Donald R. Yance, MH, CN, RH (AHG), SFO

Donnie Yance has devoted his life to developing a unique approach to health and healing that elegantly combines his passion for the latest scientific research with the wisdom of ancient healing traditions.

Educational and Spiritual Background

Yance received his herbal training through Sequoia College and is a professional member of the American Herbalists Guild. Trained as a clinical nutritionist through the National Institute of Nutritional Education, he holds certification through the National Association of Nutrition Professionals. He is also professed as a Secular Franciscan (SFO), which equips him with the breadth and wisdom to touch on the spiritual aspects of healing.

The Eclectic Triphasic™ Medical System

After decades of extensive research and clinical practice, Yance developed the Eclectic Triphasic™ Medical System (ETMS), a diagnostic and therapeutic methodology for patient care, with the goal of significantly improving patient quality of life and longevity.

Rooted in the American Eclectic herbal tradition, Traditional Chinese Medicine, constitutional energetics, and contemporary clinical nutrition, the ETMS is continuously honed by the latest scientific research at molecular, cellular and genomic levels. ETMS integrates three key branches: the human being, the external environment, and the biological environment. The ETMS forms the cornerstone for the clinical approach at the Mederi Foundation’s Centre for Natural Healing, where Yance and his team of practitioners apply this model in their work with patients. ETMS also serves as the foundation of Yance’s  formulation philosophy at Natura.

Teacher, Mentor and Author

For more than a decade, Yance has been widely respected as a teacher and mentor in the field of natural medicine and integrative care. Each year Donnie lectures throughout the United States at major conferences and hospitals for both patients and healthcare practitioners. He also conducts clinical training programs for professionals through The Mederi Foundation, a non-profit organization that serves as the research and education arm of Yance’s mission.
