Defendo, created by Bill Underwood, is the internationally approved “Occidental System of Self-Protection” designed to enable its practitioner to put an immediate end to any physical confrontation, with or without weapons, turning the attacker into the victim.

This is accomplished through joint manipulation, restraints, strikes, grips, leverages and by manipulating the aggressor’s nervous system

Direct and extremely practical, Mr. Underwood’s techniques have proven themselves through “life and death” combat situations in World Wars I and II and North American Intelligence and Law Enforcement communities.
