About Tasso International

Tasso Tasso International started its first program in 2010. It is an offspring of Tasso’s Dutch training program that runs since 1983, and of the many workshop and training activities Hans TenDam and Marion Boon have been giving for years in Europe, Asia, North America and South America. Tasso has initiated the World Congresses for Regression therapists, that started in 2003 in the Netherlands. The second was in New Delhi, India in 2006, the third near Rio de Janeiro, Brazil in 2008, the fourth will be near Izmir, Turkey in October 2011 and the fifth is planned near Toronto, Cananda in 2014. Tasso also intiated the European Association for Regression Therapists, that meanwhile became a worldwide organization.
