Castoldi’s Jujitsu
Real-World Self Defense Training in Arlington, MA
At Castoldi’s Jujitsu, we teach practical self defense designed for real-life situations, not just competition or demonstrations. Developed by Professor Dave Castoldi, this unique self defense system combines principles from Small Circle Jujitsu, Wing Chun, Judo, Wrestling, and street-proven defensive tactics to prepare students for the situations they are most likely to encounter.
Located in Arlington, Massachusetts, our school welcomes students from throughout the Greater Boston area, including Belmont, Boston, Burlington, Cambridge, Framingham, Lexington, Malden, Medford, Melrose, Natick, Newton, Somerville, Stoneham, Waltham, Watertown, Winchester, Woburn, and beyond.
Learn Practical Self Defense for Real-World Situations
Unlike many martial arts programs that focus primarily on sport competition, Castoldi’s Jujitsu trains students to respond effectively during realistic confrontations.
Students learn how to defend against:
- Unarmed attackers
- Attacks from the front and behind
- Knife threats and knife attacks
- Club and blunt weapon attacks
- Gun threats and weapon disarms
- Multiple attackers
- Seated attacks
- Ground attacks while lying on your back or stomach
- Situations involving family members or loved ones
Training begins with common self defense and mugging scenarios and progressively develops into advanced defensive skills that emphasize awareness, control, and effective responses under pressure.
Industry-Leading Weapon Defense Training
Professor Dave Castoldi is widely recognized for his expertise in weapon disarming techniques. Students learn to defend against a variety of weapon threats, including:
- Knives
- Handguns
- Clubs
- Baseball bats
- Chains
- Multiple weapon combinations
The system teaches students to maintain composure, control distance, and apply proven defensive techniques during stressful situations.
Develop Confidence Through Advanced Training

Advanced training exercises challenge students to apply techniques under increasingly realistic conditions, helping them build:
- Confidence
- Situational awareness
- Reaction speed
- Defensive decision-making
- Physical control under pressure
Our goal is to help students develop skills they can rely on when it matters most.

Differentiating Fighting Arts
A fighting art is broadly a combat-oriented system. Typically, fighting arts can be broken down into the subcategories of Self Defense, Martial Arts, and Combat Sports.
Self Defense
Self Defense can be basically defined as the use of proportionate, reasonable, force to protect oneself from physical harm.
Martial Arts
Martial Arts typically are fighting arts that focus on physical fitness, mental discipline, personal growth, and competition. Martial Arts can typically be the base of most self defense and combat sports fighting arts, but not always.
Combat Sports
Combat sports are fighting arts focused on competition. Combat sports typically have a number of rules to follow and are refereed.
