What a dreadful cliche, and yet, our instructors actually have.  Beyond over a combined century of experience in law enforcement/public safety, SWAT, military, and peace-keeping missions, our staff has instructed literally hundreds of classes to thousands of students in such organizations as Proctor & Gamble, Walmart, battered victim shelters, schools, universities and libraries.  Our training style is light, relevant, and fast-paced.  We believe you'll find them to be among the finest trainers you'll ever meet.
