“Almost 30 years ago, Substance-Assisted Therapy helped me to heal in depths that had previously been closed to me. Since then, I have not found any other way to achieve this. Based on these experiences, I have developed what has profoundly changed me further – supported by great gratitude, courageous determination, compassion and a portion of pioneering spirit – in order to make it available to others today.”

“For me, SUT is the most compelling and integrative form of therapy known to me for reaching depths of consciousness, illuminating shadow areas, dissolving blockages, and connecting with myself and my It has, more than any other, helped me become who I am.

“In my view, substance-assisted therapy is a field with immense potential that has been used far too little to date. However, many aspects that are absolutely essential, such as high-quality training or considerations regarding practical therapeutic applications, are still in an emergent state. I would like to contribute to this.”
