Here are what some clients had to say:

“In the art of Brazilian Jiu Jitsu, many get caught up wanting to learn or wanting to teach how to attack your opponent and get him to submit.  They soon realize without the right position and understanding of the body, successful attacks will be far and few in between.

Professor Harris will guide you through his methodology that will give you an appreciation of body positioning that will leave your opponent frustrated and vulnerable for your attack.  The great thing is, once you understand and realize the body positioning your attacks and escapes become almost effortless.

Best of all, with Professor Harris, you’ll have quality instruction, a vast amount of martial arts knowledge and a friendly smile knocking at your door ready to teach you tried and true knowledge of BJJ.”

“In the field of martial arts, the level of available instruction runs the gamut from superb to sub-par. With the booming popularity of Brazilian Jiu-Jitsu, this is especially so. Everyone from championship athletes to under-qualified coaches is now trying to capitalize on the name-brand recognition of the UFC, grappling, and jiujitsu.

However, for one to learn the system properly, he/she needs an instructor who is not only highly capable in the physical execution of the techniques, but one who has studied them deeply enough to be able to understand them on both a microscopic and macroscopic level, enabling them to modify the techniques to fit the varying ability levels and attributes of their students and clients.

Prof. Roy Harris is exactly such an individual.

Not only one of the most experienced Brazilian Jiu-Jitsu practitioners in the English speaking world, Prof. Harris is also one of its most forward thinking minds. Unlike many instructors who play to the egos of their students and clients by allowing them to get carried away with the adrenaline rush of exerting physical force on another human being, Harris’s method of instruction focuses on logic, leverage, legitimacy, and level-headedness.

As a medical professional who relies heavily on the use of his hands for a living, I could not place myself at undue risk of injury, despite my eagerness to study Brazilian Jiu-Jitsu. Thanks to Roy Harris’s in-home training program, he made it possible for me to train when I wasn’t tied up with patients, consults, or research projects. His emphasis on safety, logical progression, and digestible skill sets made it possible for me to achieve a basic level of comfort and ability on the ground within a minimum of hours. Best of all, I didn’t have to break away from my obligations in Los Angeles to drive down to San Diego to study with him. Instead, Prof. Harris’s on-site training sessions helped me save a tremendous amount of time and energy, allowing me to train in the comfort of my own home, save commute time, spend evenings with my family, and service my patients without missing a beat.

If you are looking for a truly world-class martial arts expert who is light years above and beyond the corner karate studio experience, I encourage you to schedule an on-site session with Prof. Harris.”
