I found psychodrama to be a very potent therapy method because it brings about emotional and physical (through the body) transformation which is longer lasting than analyzing and resolving only through the brain.
I am a trainer and I find myself using techniques such as sociometry, role interviews and protagonist role plays from psychodrama more often in my sessions. Personally, it has helped me resolve some issues in some of my closest relationships which I have been struggling with for years.
As a trainer, I experienced Jochen to be amazingly transparent, honest and self-aware. He is always fully present, strict when he needs to be, open about his own blocks and shortcomings, and in touch with his emotions. He serves as a great role model for me.
