Since I began training with Kyoshi Sherbourne, I have learned many new insights and directions to take with my martial arts training. His knowledge of Karate, Kobudo and Jiu-Jitsu has allowed me to blend different aspects of martial arts resulting in more effective, more complete and more versatile self defense applications. In addition, his breadth of knowledge is indispensable when teaching Students and and he always has something new to teach each training session, keeping students interested.
