For Patients – Mederi Centre for Natural Healing
The mission of Mederi Centre for Natural Healing is to apply the ETMS approach to help restore and maintain optimal health and wellbeing, to improve quality of life, and to promote longevity for our patients.
We view healing as a transformational process that transcends the physical, and actively involves the spiritual, mental, and emotional aspects of the individual. We are dedicated to serving our patients both face-to-face in our Ashland, Oregon clinic and virtually via telephone and videoconference. Learn More >
Since 2005, the Mederi Foundation has trained hundreds of practitioners to apply the principles of the ETMS to patient care. The training program educates practitioners about all facets of the ETMS so that they can create personalized patient protocols, and increase their expertise in diagnostics and therapeutics.
Participants have come from all over the world, and include medical doctors, naturopathic doctors, oncologists, acupuncturists and various other health care providers. Learn More >
