Welcome to Koshou Ryu Ju-Jitsu Self-Defense

Koshou Ryu Ju-Jitsu Self-Defense is a modern Ju-Jitsu system that is based on older forms of traditional Ju-Jitsu, complimented with a foundation of Karate and other styles of martial arts.  Koshou Ryu Ju-Jitsu includes all ranges of combat, from standup to ground survival.

Koshou Ryu was founded in 1997 by the Chief Instructor, Kyoshi George Cushinan, and has been taught to 1000’s of students throughout Markham over the past 23 years.

Due to COVID19, the City of Markham classes taught by Renshi Gary Bulian are currently running via ‘zoom’ (Kids class) for the Summer, and will likely run by ‘zoom’ again in the Fall (Kids/Teens/Adults).  Stay tuned for updates.

The Markville Fitness location classes taught by Kyoshi George Cushinan are on hold until further notice.
