Welcome to Order of lsshin-Ryu Martial Arts!

Welcome to the website for OI Martial Arts! The OI was established in 1971 and is a 501(c)3 non-profit organization dedicated to sharing the benefits of our blend of martial arts.

Martial arts training not only covers physical activity to promote fitness, but also the mental acumen to understand self-defense and the spiritual aspect to believe in yourself. People come to train for many reasons and we endeavor to make every student’s experience a good one.

If you are looking for a member school to train in, please visit our Dojos page and contact the instructor directly. Thank you!


With a heavy heart, the Order of Isshin-Ryu Martial Arts  organization announces the passing of a great man and Isshin-Ryu legend – our founder, Grandmaster Walter E. ‘Toby’ Cooling.

“Your Sensei only has the rest of his life to

teach you, and that is never long enough!”

– Sensei William Maren
