Our History



We have been a prominent school of martial arts for nearly 30 years here in the South Bay!

Our dojo was founded in 1990 by Sensei Bruce Schram and his teacher Roy Oyakawa. Bruce is a 7th degree black belt in Shorin-Ryu, he also had a 1st degree black belt in Kenpo and Tae-Kwon-Do. Bruce was a 5 time National Koshiki Karate Champion and a 6 time World Koshiki Karate Champion. Sensei Schram retired a few years ago and passed the school on to his three senior students. They continue to pass on the knowledge they've learned to the next generation of students. 

Shorin-Ryu was created by Sokon "Bushi" Matsumura. It translates to "young or small pine forest." Our dojo trains in a specific branch called Shidokan Shorin-Ryu. Shidokan means, "House of the Way of the Warrior." Which was originated in the 1930’s by Chibana Sensei. 

Karate-Do comes from the kanji KARA (empty), TE (hand) and DO (way). Empty Hand Way. Not all dojos incorporate the DO into their training. The DO is the way in which you apply what you learn in Martial Arts into your every day life. We strive for a true balance of mind, body and spirit.
