Robert Johnson


Robert joined GD Jiu Jitsu Prescott in 2010 already having 20 years of martial arts experience under his belt. He had already earned a 3rd degree black belt in karate and had spent many years traveling around competing and training with some of the best in the world. 

After his many years teaching and training, Robert jumped at the opportunity to once again put on a white belt and took full advantage of the world class instruction being offered by Professor Steve Judson.

He quickly gained a firm grasp of the basic principles and concepts of Jiu Jitsu and begin to develop a technical and aggressive style of his own which allowed him to find early success in competition.

As Robert worked on honing his skills in the junior ranks , he also begin to lend his experience as an instructor to help develop a 5-7year old program and assist with teaching the older kids and adult classes.

A permanent fixture on the mats, Robert taught and lead by example doing his best to uphold the highest level of honor and respect both on and off the mats as well as in competition.
