The Nathanson family of nearby Canoga Park runs the Academy of Brazilian Jiu-Jitsu. All are master martial artists with many years of training and competition in a variety of styles.
The martial-arts school is "known for its welcoming personality, its collection of high-end athletes and its spectacular user-friendly teaching style," states the Academy's website.
In addition to classes offered all weeklong, seminars by master guest-instructors also take place frequently. This is an excellent West Valley martial-arts resource.
