Like all martial arts, we have influences that inform our system and style. Mo Duk Pai incorporates these lineages, systems, styles and philosophies in an evolving curriculum based on the foundational studies of Professor King, flavored by the additional studies of teachers throughout the system. As Mo Duk Pai has evolved over the last few decades, we’ve incorporated strategies and techniques from even more fighting arts in order to evolve into our own unique and dynamic system. What follows is a look at some of the family tree of Mo Duk Pai.


One of our main branches is Kajukenbo. Professor King studied under Grandmasters Rich Mainenti and Al Dacascos, and currently holds an 8th degree blackbelt in this martial art. Here’s a long format video from the series “Fight Quest” that has a good overview of some of the training and tactics that come to us through the Kajukenbo family branch.

Modern Arnis

In any fight, someone may pull a weapon. Some of Mo Duk Pai’s strategies of stick and knife weaponry and fighting techniques come from Grandmaster Remy Presas, who developed a Fillipino martial arts style called Modern Arnis. Here’s a video of Grandmaster Presas in action.

Small Circle Jiu-Jitsu

We incorporate joint locks and controls from Small Circle founder Professor Wally Jay. Professor Jay was a legendary Jujitsu influence in the world of martial arts. He was an active teacher and promoter into his eighties, and here’s some footage of the master in the last decade of his life, demonstrating the effectiveness of Small Circle.

Tai Chi

Professor King studied under Sifu Gregory Fong, a tai chi master who had a great influence in the Tai Chi community in the Northwest United States. Here’s a video of the master doing the Chen Tai Chi Form. As the martial arts community has evolved, so have we, and the above videos are just a short list of the many styles and systems we have incorporated. Others include Western boxing, Systema, Brazilian Jiu Jitsu, Sambo and Krav Maga, among many others. As the martial arts evolve, so will we.
