What it is

Combat Defense Systems is a self-protection program for working professionals, built by Coach Greg from 30 years of combat sports and martial arts. Most of self-protection happens before a fight ever starts, so training begins with situational awareness and threat assessment, then backs them up with simple, proven unarmed skills.

Precise. Tactical. Practical.

Why it's different

  • Awareness first. Learn to read your environment: where you're going, how risky it is, how others perceive you, and how to move to avoid trouble before it starts.
  • Built from real fighting, not choreography. When avoidance isn't an option, every technique comes from systems tested in competition and adapted for real-world situations.
  • Quality over quantity. A small set of efficient skills you'll actually remember under stress, taught personally by Coach Greg, not a franchised curriculum.
  • Made for your world. Training fits legal, corporate, government, nonprofit, security and healthcare professionals.
