About The Technician Dojo

Our Story

About The Technician Dojo

Master Steven Hatfield brings decades of martial arts experience and a practical, no-nonsense approach to training at The Technician Dojo. His background spans traditional and modern martial arts, with a foundation in Goju Ryu (Okinawan Karate) and training completed in Japan and Okinawa.

The system he created, Ryu-Saiichi-Do Kenpo Karate Jutsu, is a modern expression of those traditional foundations, designed for practical self-defense in the real world. Rather than treating Karate, Judo, and Jujutsu as separate disciplines, Master Hatfield helps students understand how striking, throwing, grappling, joint manipulation, and defensive tactics work together.

Students are encouraged to explore why techniques work, recognize when they are appropriate, and develop the ability to apply fundamental principles under changing circumstances. Progression is individually based. The Technician Dojo is not a belt factory.

Our Mission
"Develop capable, adaptable martial artists with the skills, confidence, and understanding necessary to protect themselves and others."
