Certified Sourcetuning Coaches

Jens Roth is the inventor of SourceTuning. As an artist he sees himself on a constant journey of discovery with the gift of looking with wonder and curiosity at people and their deep longings and motivations. As a coach, director and actor he wants to open spaces for new insights into contexts that provide the ground for solidarity, empathy, communication and high acting quality.

Jannika Petermann finished her master's degree in psychology in 2019. Alongside her studies, she worked in the field of theater education. When she got to know the technique SourceTuning, it was immediately clear to her that she had discovered a valuable interface between her two passions, psychology and theater.

In 2019, she therefore completed her training as a certified Source Tuning Coach and researched the positive effects of the technique on our psyche in her master's thesis.

I support and encourage actors to make truly fun offers. In order to go with it joyfully and self-responsibly into the creative collaboration with ensemble and direction.
