Andreas Güttner

Andreas Guettner is a martial arts instructor, author, and co-founder of the RoninZ Martial Arts School. For many years, he has combined traditional martial arts such as Ju-Jutsu-Do, Kali Kuntao, and Filipino Martial Arts with modern pedagogy, functional training, and personal development.

Alongside his work in martial arts, he teaches at the Sprachheilzentrum Ravensburg at the elementary school level. There, his main focus is on physical education as well as forest and nature-based education, supporting children holistically in their motor, social, and personal development.

In addition, Andreas is active in experiential education, including work in low- and high-ropes courses, and is involved in youth leader training within the German Ju-Jutsu Association. His work is characterized by clarity, safety, trust, and the belief that movement can help young people grow strong for life.

In his books, he shares practical knowledge, clear structures, and proven concepts for children, teenagers, and adults—always with a focus on movement competence, self-confidence, presence, and sustainable development.
