It’s not often that a martial arts academy has a Grandmaster teaching classes, especially in San Diego!

San Diego Sidekicks Martial Arts Academy was founded by Grandmaster Maurice Orange. GMO opened his first Taekwondo school in 1980. He founded San Diego Sidekicks Martial Arts Academy in 1989.


Still running the academy, and often teaching classes, legendary Grandmaster Orange “GMO” instills his students with a keen sense of self confidence and respect for elders. Hence he’s coaching both students and their parents about life.
