I am now the Grand Master and ranking black belt for the Kifaru-Karate system. I have a vast experience in Karate tournament sparring and numerous Championship titles. I have authored three books, the latest is Disarm and Disable: The Active Shooter Defense Guilde. I retired from the Reno Police Department and Department of Homeland Security. I own and operate Leading Edge Threat Mitigation which seeks to provide real world personal safety tactics and techniques against violent offenders.
