About Us - SHIELD Women's Self Defense

SHIELD Women's Self Defense System empowers women and girls by training them on how to fight back a much stronger opponent in close-range situations. SHIELD emphasizes on using leverage and lower body strength to generate power. Based on a mixture of martial arts principles, self-defense and street fighting skills, SHIELD Women's Self Defense was created exclusively for women and girls.

Awareness, verbal and psychological aspects of self defense are incorporated in SHIELD Women's Self Defense System. Completing SHIELD Women's Self Defense training will increase self-confidence, enhance personal safety, raise awareness and become more comfortable on how to use one's body as a weapon.  


Our mission is to empower women, eradicate sexual assault and even up the playing field through our unique self defense training system.


Our Vision is for women to have self defense skills and capability to be destructive to anyone attempting to violate them.

Our Vision is for SHIELD Women's Self Defense System to be the standard self-defense training system for women and girls.
