About us

Martial arts is a school for life. The GKMAF Krellmann teaches the styles Jung Do Kung Fu and Dae Ryeon Do Samurai. The different styles have a different focus with regard to the weapons with which the basic techniques are learned. Martial arts with or without weapons promotes self-confidence and coordination. 

We value a comfortable atmosphere and respectful interaction with each other. Learning a martial art teaches discipline and respect, creates self-confidence and has a positive effect on the mind and soul as well as significantly improving strength and fitness.

We train in the rooms of the Yun Song Academy on 400 m2 divided into 3 training rooms.  

We regularly take part in seminars and open tournaments in Switzerland and abroad.

History of the school

Stephan Krellmann and Pirmin Andermatt founded Yun Song Akademie GmbH together in 2009 and taught martial arts. The school moved into the premises at Bachweid 3 in Baar in 2011. After Pirmin Andermatt's commitment as a municipal and cantonal councillor meant that he was able to devote less and less time to the martial arts school, Stephan continued teaching martial arts under the name Global Korean Martial Arts Schule GKMAF Krellmann.

The old slogan “Experience martial arts" is still our motto.
