Chris Ranck-Buhr
Master Instructor
Chris started training in 1988, earned his Instructor certification in 1990, and became a Master in 1996. Since 1990, he has trained thousands of people around the world, produced a multitude of video products, and written three books and hundreds of articles and essays on practical violence. He enjoys working at both ends of the training spectrum — giving equal effort to the education of Master Instructors and absolute beginners alike. He’s only as good as the last group he trained, however, so his resume goes in the shredder at the beginning of every new session.
“It’s not magic — things don’t break because they’re supposed to, or you wish they would. Things break because you break them.”

Derrick F.
Master Instructor
Derrick earned his Instructor credential in 1994 and became a Master in 2011. What he sought was something stripped of fantasy and wishful thinking, something grounded in the tangible world, training that was as old — and as simple — as hominids themselves. Just physics and physiology — applied pathology — consistent with his military experience and medical education. He found it here, and has been training ever since.
“The secret ingredient? Contempt in the fists.”
