Amir Weiss

Founder of the Weiss Institute and Weiss Method

In 1980, Amir traveled to South America to research ancient cultures and live with an isolated tribe deep in the Ecuadorian jungle. There, he met a variety of spiritual healers and had his first experiences with natural healing methods, energy fields, and electromagnetic processes in the human body.

In 1983, he began studies at Jerusalem University, majoring in crystallography, biology, and philosophy at the Faculty of Geo-sciences. It was while residing in Israel in 1986 and practicing bioenergetic healing methods that Amir developed the “Weiss Method,” an innovative approach to combating unwanted habits and addictions.

Amir has personally helped over 10,000 people. He has also trained a select few who now work in their respective countries as Certified Weiss Method Practitioners. Together they have helped thousands more use Weiss Method to overcome addictions and compulsive habits in England, Ireland, Canada, Australia, Germany, Belgium, Holland, Israel, and the United States.
