Assistant Instructors
At Pacific JuJitsu Kai, all students learn to teach as part of their training curriculum since that is one of the best ways to learn. As students progress to higher ranks, they will be asked to teach more often. Students who are dedicated to helping run classes can become Official Assistant Instructors who take on more responsibility in the dojo. Currently Dolly Wyatt is an Assistant Instructor at Pacific JuJitsu Kai-Palms and Vanessa Carlisle is an Assistant Instructor at our UCLA Martial Arts Program Danzan Ryu Jujitsu class.
