As he traveled around in pursuit of a career in law enforcement, he was able to sample many different martial arts before discovering Ninpo Tai Jutsu. This was to become a life changing discovery.

During his years of training he was a personal student for 17 years of both Sensei Chadwick Minge and Grandmaster Shoto Tanemura of the Genbukan Ninpo/Ninjutsu Traditions, where he learned the arts of the Ninja, Jujutsu and many other family lines of martial arts. During his last trip to Japan, Kyoshi Weekley tested for and received his certification and title of Kyoshi, (Master Teacher), from Soke Tanemura.

Association was created with the concept of having a group of highly qualified martial artists in different styles available to help martial artists and martial arts instructors become better at what they do. NINMAA gives martial artists a common ground in which to advance the aspects that are common to all martial arts. Kyoshi Weekley continues to serve as President of N.I.N.M.A.A.
