Jay Walker  (Certified Krav Maga Instructor)
Jay Walker is the head instructor at our Moorpark Krav Maga location. Jay has devoted most of his life to training, instructing and competing in various forms of martial arts. His interest started at a young age after watching Kung Fu, Bruce Lee movies, and Billy Jack as a young boy. He was unable to start his training until he was 16 due to asthma and other childhood illnesses and has never looked back. Jay was fortunate enough to use his passion as a way to work his way through college training local, national and world champions from fighters both amateur and professional. "Breaking Barriers to Build Brighter Futures" was the back bone of his teaching style. "Everyone has a reason to join a martial art program whether it is for self protection, confidence, fitness or a drive to compete. It is up to the instructor to help each student to reach their full potential and goals." Before relocating to the Los Angeles area, Jay became interested in Krav Maga and wanted to find an organization and school in his area that matches his beliefs, drive, and passion. After extensive research he found Burbank Krav Maga and after one class, he was hooked. "Burbank Krav Maga and all the affiliate schools of the American Krav Maga Federation share the same vision. No egos, family first, and get home safe" states Jay. Now he shares his instruction as well for Burbank Krav Maga and America's Best Moorpark Krav Maga.
