Parents ask us
Will martial arts make my child more aggressive?
No. Jiu-jitsu has its roots in self-defense, and we teach kids that violence is not the answer to their problems. They learn to stay calm and avoid a fight, and to protect themselves only when there is no other way.
My child isn't very coordinated. Will they get hurt?
Our coaches work with kids of all abilities and ages. Your child learns at a pace that is comfortable for them, and physical safety comes first in every class.
Can it help with focus at school?
Training teaches focus, discipline, self-control and respect. Kids practice paying attention to a coach every class, and those are the same skills they need in school.
