CONFIDENCE
Our classes are designed to build confidence and skill very quickly to transform yourself from the defender to a ferocious aggressor in a split second.
SELF-DEFENSE
We teach a defensive system that deals with personal safety issues in the context of defending against both armed and unarmed attackers, muggings, street attacks, and sexual assaults.
EFFECTIVE
Learn to quickly inflict as much punishment as possible to your attacker, using wrist locks, chokes, groin kicks, strikes, throws, etc. to incapacitate and control your attacker - so they don't control YOU!
