Don Jitsu Ryu Karate was founded in 1970 by Grandmaster Professor Don Jacob — a system built not around sport, but around the disciplined development of the whole person. Born in Trinidad & Tobago, Professor Jacob earned the title of 9th Degree Black Belt (Hanshi) and is respected as one of the most accomplished martial arts masters in the world.
He developed Don Jitsu Ryu as a comprehensive martial arts system blending traditional styles — karate, kung fu, judo, jiu-jitsu, and weapons work — into a practical, complete discipline. His system teaches not only physical skill, but confidence, self-control, respect, and mental strength. Professor Jacob has trained students and instructors across six continents and more than 50 countries — competing and demonstrating in international arenas, from ABC’s Wide World of Sports to Trans World Sports.
At Purple Dragon ATL, we carry this tradition forward as a direct continuation of Grandmaster Jacob’s mission. Every class, every belt test, and every challenge on the mat is infused with the principles he built over five decades of practice.
