Kaicho AJ Weimer is the visionary founder of the Martial Arts Unlimited Association (MAUA) and the creator of Total Fighting Concepts (TFC JuJitsu), a self-defense system established in 2004 and recognized by the late O-Sensei Porter from the United States Martial Arts Association. With over eight black belt rankings, AJ’s expertise spans Jiu-Jitsu Submission Fighting, Submission Wrestling, Aikido, Filipino Martial Arts, Combative Weapons, and the Japanese sword.

AJ’s martial arts journey began at age 6, when he and his father joined a Tae Kwon Do studio together, igniting a lifelong passion for the disciplines. During his service in the United States Air Force in the 1990s, stationed at Yokota Air Base in Tokyo, Japan—the birthplace of many martial arts—he immersed himself in intensive training, earning multiple black belts and honing his skills.

Beyond the dojo, AJ’s career in international security included high-stakes roles in personal and executive protection for celebrities and VVIPs, as well as work with a civilian security firm where he also participated in kidnap, ransom, and extortion operations across Asia, Europe, and South America.

As MAUA’s Executive Director, AJ oversees global operations, delivering expert security consulting, close-quarter combat training, and corporate self-defense programs. His leadership and innovative approach continue to inspire and empower martial artists and professionals worldwide.
