After studying medicine in Geneva , Dr. Daniel Dufour (1951 - 2021) worked as a surgeon in developing countries and as an envoy and coordinator for the International Committee of the Red Cross (ICRC) in war zones. From 1988, he headed the Vitamed clinic in Geneva and practiced a holistic approach that treats the deeper causes of an illness rather than the symptoms.

Dr. Dufour developed the “OGE” method in 1997 and has appeared as a trainer and speaker at OGE seminars in Europe and Canada.
