In 1977, I started the study of Taekwondo at the West Marin Martial Arts School in Fairfax Ca.  I Studied Taekwondo for four year where I obtained the level of Brown Belt.  After college, I joined the Mill Valley Police department in 1983.  In 1986, I transferred to the San Rafael Police department where I spent the next 14 years.  During that time, I become one of the department’s Defensive Tactics, Firearms and Baton Instructors.  I also spent 10 years on the SWAT team, the last 3 years as the Team Leader.  In addition to teaching Defensive Tactics, Firearms and Baton training to the officers at the department, I also taught Defensive tactics and baton training to the new recruits at the Napa Police Academy. While at SRPD, I decided to change my Martial Arts training from Taekwondo to American Kenpo Karate and joined the Marin Kenpo Karate School in San Rafael, Ca.  I felt that Kenpo Karate was more suited for Law Enforcement than Taekwondo.  In 2009, I was promoted to Black Belt in American Kenpo Karate.  Shortly after that, I decided to start training full time in Combat Kenpo.  In 2013, I was promoted to 2^nd degree Black Belt in Combat Kenpo by Master Instructor Jef Dix.
