Grandmaster Murdock will be in charge of all decisions and all operations for the system. On March 15, 2019 Professor Casarez had 70 years in martial arts. Soke Casarez officially retired at age 82 but still enjoys showing a few techniques time to time. This man is a legend in the martial arts. It's a great privilege to have trained under him for nearly 40 years. Master Wilson is an inheritor however is not actively teaching the system as a whole. He continues to teach select techniques that he has included in his own system.
