Karate 4 Kids USA, North Hollywood

At Karate 4 Kids USA, a team of experienced instructors draws from a diverse range of training and martial arts styles to help kids develop self-respect and a sense of discipline while having fun and getting fit. In after-school programs, they teach kids karate and Tang Song Do techniques, whose katas and kicks help kids build healthy muscles and bones to give them the advantage in high-stakes hop-scotch tournaments. Their full-day camps keep kids occupied during summer vacations with martial arts drills, dodgeball, and games. And the fun-loving staffers invite parents to take time for themselves by dropping the kiddies off for Ninja Nites—four supervised hours of movies, pizza, and games.

Though their main focus is teaching children, they also helm a lineup of adult martial arts classes, including muay thai kickboxing and self-defense.
