After her carpentry apprenticeship, Kathrin Brunner decided to step onto stage. She completed her acting education at the Berliner Schule für Schauspiel. Her paths then led her to various theaters, such as Parchim, Celle, Brandenburg, Hamburg, Quedlinburg and the mountain theatre Thale. She also works as a speaker and acts in front of the camera, both for television, as well as for short films and advertising or image films.

In addition, Kathrin continued her education as a theater pedagogue and since 2015 she regularly gives theater and film classes, especially for children.

In 2017, she founded her own mobile children’s theater. There she is not only acting, but also building puppets and stage sets.
