Chris Ranck-Buhr

"You swim to keep breathing — we put hands on people to do the same."

Since 1990, Chris Ranck-Buhr has trained thousands of people around the world to use violence as a survival tool. He's also produced a multitude of video products and written three books and hundreds of articles and essays on practical violence.

He has trained 53 Instructors (a three-year program), nine of whom have become Masters (a 10-year program).

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.
