About SHIELD Women's Self Defense System ®

Partial Client List


Since 2003, 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. Unlike other self defense or martial arts, 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 System ® was created exclusively for women & girls. 


Awareness, verbal and psychological aspects of self defense are  incorporated in our women's self defense classes in Los Angeles area. Completing SHIELD  Women's Self Defense classes 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 and girls, eradicate sexual assault, and even up the playing field through our unique self defense training system.




Our Vision is for women and girls 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.
