Our Story

About The Technician Dojo

The Technician Dojo is a self-defense school on Parsons Avenue in South Columbus, founded and led by Master Steven Hatfield. Our primary art is Ryu-Saiichi-Do Kenpo Karate Jutsu, a system Master Hatfield developed over more than 25 years to address the practical demands of real-world confrontation through striking, weapons, and ground work taught as one cohesive curriculum.

We believe training should be shaped around the student. A child beginning at age 4 and an adult with no prior experience move through the same progression, each reviewed individually and advanced when they are ready. There is no fixed belt timeline, and advancement is not a reward for time spent. It reflects what the student has actually developed.

Our programs include Ryu-Saiichi-Do Kenpo Karate, Judo and Jujutsu, Firearms Education and Certifications, and TENSHINKIDO Holistic Services. We are not a competition school or a sport academy. We train people who want to understand their art, develop real capability, and apply what they learn with judgment and responsibility.

Why Train at The Technician Dojo

Real-World Self-Defense

Training here has one standard: will it work when it matters. We do not train for trophies or belt counts. Technique earns its place by what it can do.

Not a Belt Factory

Students advance when they are ready, not on a fixed calendar. A black belt in Ryu-Saiichi-Do Karate takes four to ten years for most students.

A Complete System

Four disciplines under one roof: Ryu-Saiichi-Do Kenpo Karate with Okinawan weapons, Judo and Jujutsu, NRA-certified Firearms Education, and TENSHINKIDO Holistic Services.

Community

Students at different ages and experience levels work alongside each other under the same certified instructors and the same standards.

"I could not speak more highly of Sensei Hatfield. The environment and class culture speaks for itself, but the safe space to learn and the disciplined curriculum is like no other in the area. We have visited a number of facilities around Columbus and this place is hands down the best around."

Karen Tussey

"As a lifelong martial artist myself, I can confidently say that the real life self defense training that is taught far surpasses any expectations I may have had beforehand. Master Hatfield is a true martial artist that refuses to sugarcoat and tells it like it is. His compassion for his students and the love he has for the arts is truly admirable."
