He taught as a Professor of Criminal Justice for seven years, teaching college courses in Criminal Law, Criminology, and Use of Force to students training to be police officers.

Jiu jitsu science in Kinesiology

In 2006 Professor Medley began studying Kinesiology at the University of Texas graduate school. Kinesiology is the scientific study of human body movement. Medley completed 30 graduate hours of masters study in:  Body Mechanics, Muscle Physiology, Sport Psychology, Nutrition, and more. This coursework helped put science behind much of what Medley already knew through the practice of jūjutsu. He completed all of the coursework for a Master of Science degree, but did not complete a thesis research paper in order to graduate from UT.

Jim Medley has had the honor to travel to Japan on two different occasions. He has trained jiu jitsu in Tokyo in private lessons with Master Yuki Nakai. Sensei Medley holds a 4th degree black belt (yodan) in Japanese jūjutsu under the United States Judo Association Jujitsu Division.      

In 2009 Medley began studying Gracie/ Brazilian jiu jitsu (BJJ) to broaden his self-defense skills. He quickly learned to appreciate the strategic advantages of using the ground as an ally in defeating larger, stronger opponents. During these last 15 years of BJJ study, he  has had the privilege of training under a number of world famous instructors, including: Ricardo De La Riva, Royce Gracie, and Ryron and Rener Gracie.

In 2014 Jim Medley first trained with Grandmaster Hélio Gracie's grandsons, Ryron and Rener Gracie. He then began training under the Gracie Academy jiu jitsu curriculum. This program was rebranded Gracie University in 2017, and is the only structured jiu jitsu curriculum of its kind in the world.

While training in the Gracie University program, Medley was also training in Brazilian BJJ under Royce Gracie (Hélio Gracie's youngest son). Royce teaches a Gracie BJJ jiu jitsu self-defense system very similar to the system taught at Gracie University. Both systems are closely based on the techniques taught by Hélio Gracie as depicted in his famous textbook for self-defense.

Professor Medley earned his black belt in Gracie jiu jitsu from  Gracie University. He continues to learn how to apply jiu jitsu principles into his life in areas beyond fighting and self defense. He is also learning more about how to teach self-defense to groups with unique needs -  women, teens, police officers, and older adults.                  

Self-defense instructor certification

In addition to formal martial arts credentials,   Jim Medley is also a life-time certified Self Defense Instructor by the American Sports & Fitness Association (ASFA). 

Professor Medley does not teach jiu jitsu from merely a theoretical perspective. He has USED jiu jitsu in his jobs and in grappling competitions. As outlined above, he was a police patrol officer and had several occasions to use jiu jitsu in making arrests and in self-defense. 

 

While in transition from law enforcement to becoming an attorney in the late 1990s, Medley worked as a security bouncer in a dangerous Houston, Texas nightclub. In this environment he was presented with multiple situations to rely on leverage, takedowns, and joint locks to manage aggressive and intoxicated people.

While studying Brazilian jiu jitsu, Medley participated in multiple BJJ competitions in order to get experience applying jiu jitsu principles under the stress of attacks from skilled opponents.

Sport competitions are not encouraged for beginners at LJJA, but competitions do have some value in preparing an experienced student for the anxiety and aggression of real self-defense. 

Expert in Self-Defense/ Use of Force Law

Jim Medley holds a Doctor of Jurisprudence degree from the University of Houston Law School. He has been an attorney for over 20 years and is licensed to practice law in Colorado and in Texas. Professor Medley has focused his practice on criminal law and has represented many clients in use of force situations. He has carefully researched legal aspects of self defense and case law applicable to self defense and police restraint techniques for many years.

As one's knowledge of and the ability to inflict injuries on others grows, so does the moral and legal responsibility to use those skills only when non-violent alternatives have been exhausted. Professor Medley teaches the legal limitations on use of force, as well as helping students navigate the ethical considerations of deciding when and to what degree force should be applied in a confrontation. This is one reason jiu jitsu is the most appropriate martial art for self-defense, as BJJ offers a continuum of options of how to control aggression at the choice of the Brazilian BJJ Lakewood student.
