Thoughts on Chuck Jefferson Judo

  • I’ve had the thrill of watching Chuck compete at high level tournaments since he was a teenager competing in Southern California. Since then, I’ve had the honor and privilege of him teaching clinics and camps on my mats, and I can tell you that my students and I always learn something new. The students of Chuck Jefferson’s Judo are very fortunate to have such a high level instructor with such a passion for teaching in their area.

  • Chuck Jefferson was a national judo champion, Panamerican champion. He was a great success as a competitor. He has also coached at different camps attended by both of my daughters, Ronda, who was a world and Olympic medalist, and Julia who was only 11 years old. What impressed me most about Chuck is he devoted his attention to BOTH of them. People who can become a judo champion are rare. People who can make every child who walks through the door feel like a champion are rarer still. I would trust Chuck with my own children – in fact, I did. I cannot recommend anyone more highly than that.

  • Chuck was serious about learning Judo when he first started. He never let other sports interfere with his judo training. It was a pleasure to watch him grow in to a “World Class” competitor. As his first teacher, I am honored that he has decided to teach judo. He has a lot of knowledge to impart to his students.
