EARTh's 20th Birthday!
EARTh was founded in Frankfurt in 2006 by 36 members from seven countries. Since then, our community has grown to almost 400 members across 38 countries worldwide. As we celebrate our 20th anniversary, we thank all our members whose dedication, presence and hard work have made EARTh a leading international community in the field of regression therapy. On this page, we will regularly share social media posts, articles and video interviews celebrating EARTh’s 20th anniversary. Join the celebrations!







Meet our dear Father EARTh, Hans TenDam; founder of Earth Association for Regression Therapy. He had written these words following the 2nd annual convention of EARTh, in 2007:
“What has stayed with me from the Second Summer School of EARTh in Istanbul, was its sheer vitality. There is something about truly international encounters that national confer ences and national workshops lack. Every thing was vital, even our misunderstandings and our confusion at times. We went home, full of plans, full with ideas, full of energy. I met the other Board members, both the old and the new ones, and we talked and discussed and compared ideas and possibilities and desires and ambitions. I started to call them my board. And even if I left a meeting tired, late at night, I sensed the vitality of my colleagues, of myself, of our field. We are not just an association and a board, we are a movement. We seem to be on a wave.” We are still riding the wave!
