The MASTRO DEFENSE SYSTEM

From principle to practice

Developed from real-world security and protection experience, MDS delivers practical self-defense for everyday situations.
Awareness, adaptability, natural movement, and preparedness form the foundation of the Mastro Defense System.
Hands-on training transforms MDS principles into practical skills designed for real-world situations.
Where did the system come from? • Founder: Fred Mastro, drawing on his extensive experience in private security and personal protection. • Origins: Developed from practical experience in real-world security environments rather than traditional martial arts competitions. • Purpose: A practical approach to personal protection emphasizing awareness, adaptability and effective responses to potential threats.
What makes the system different?
• Real-World Focus: Built from actual experience in nightclubs and security environments rather than traditional dojos. • Natural Reactions: Emphasizes using natural body mechanics, instinctive reactions, and targeting vulnerabilities over artistic or sports-based moves. • Situational Awareness: Teaches rapid threat assessment, survival strategy, and pre-emptive or quick calculated responses to chaotic altercations. • Wolf Pack Mentality: Promotes a family-like support structure, training individuals to become capable leaders ("alphas").
What will participants actually experience? • Adaptability: Instructors adapt training to real-time scenarios rather than relying on a rigid fixed curriculum. • Combat Elements: Integrates empty-hand combat, ground survival, knife defense, and the use of improvised weaponry. • Mental Toughness: Places heavy emphasis on psychological preparedness, rapid threat assessment, and aggressive disruption of an attacker's initiative.
• Close-Range Combat: Utilizes high-impact natural weapons like elbows, headbutts, knees, hammer strikes, and everyday use items.
