This school was founded in 1987 by Sifu Jon Rister with strict dedication to the comprehensive study of street effective martial arts. It was named Wu Hsin Kuen (pronounced Woo Shin Koon) can be translated from Chinese to mean "no thought fighting" or "non thinking fist". Having the ability to react and flow naturally when faced with a dangerous situation can make the difference between success and failure.

We moved to a new location in 2007, taking the name Rister International Martial Arts and leaving the name Wu Hsin Kuen to our sister school in Finland. Our goal, however, has remained the same - to build better individuals through martial art training.
