Mederi Care® / ETMS Model
Report
Throughout more than thirty years of clinical practice, Clinical Master Herbalist Donnie Yance's philosophy and practice has evolved into an integrative model called Mederi Care or the Eclectic Triphasic Medical System (ETMS).
This system is a distinctive approach to healing that calls for the integration of traditional, wholistic medicine with modern, allopathic medicine-thus creating a custom-tailored approach for each individual that relies on scientific research, logic, common sense, and intuitive wisdom.
