  Master Coach- Jerry Wetzel

Jerry Wetzel has been training exclusively in reality-based combat for over 10 years. In 1999, he founded Centerline Gym; an organization dedicated exclusively to researching the realities of violence and developing tools and tactics to deal with them. He has appeared in magazines and numerous instructional videos.

Since he began training, Jerry has had the privilege of training with some of the world’s finest instructors. Among other achievements, he has received:


  • Jerry is the former VP of the worldwide Crazy Monkey Defense Program.

Jerry Wetzel is dedicated to discovering the TRUTH in combat. Not the fantasy of combat, not the Hollywood image of combat, and not the ritual of combat. To do this, Jerry believes it is of utmost importance to take biological, psychological, emotional, and behavioral factors into account and then apply them to a resisting opponent under realistic conditions.
