Our Site


IMPACT Personal Safety has been training women and men, teens and children in self-defense and personal safety for 40 years. Our goal is for every person, regardless of age, gender, race, or physical or mental ability, to be able to go where they want, when they want, day or night, feeling comfortable and safe moving through their daily lives.


As a recognized expert in the field of personal safety, IMPACT has been cited in numerous books and research studies.  We’ve been featured on shows such as “Oprah”, “20/20”, “Dateline”, and many news shows. And if parody is a measure of cultural iconography, then we’re flattered to have been spoofed on “Saturday Night Live”, “King of the Hill” and in National Lampoon.


The full-force form of self-defense taught by IMPACT has its origins in the 1970s when a female black belt was assaulted and raped by two men.  This prompted a group of martial artists to study the different ways in which women and men are assaulted and to seek out the most effective means of real-life defense.


The IMPACT training method is cutting-edge, innovative, and highly interactive.  Since the human response to fear or stress is a rush of adrenaline, we teach using real life scenarios that allow students to feel what it is like to experience the adrenal state. This is what makes our training more realistic and more practical.

IMPACT cambia vidas. Tomar las riendas de su propia seguridad personal es un cambio de juego. Una vez que crees que vale la pena luchar por tu vida y que tienes derecho a vivir una vida segura y libre de violencia, puede producirse una transformación en tu forma de afrontar la vida.


Sabemos que incluso comprometerse con una clase IMPACT puede ser un gran desafío para algunos estudiantes. Muchos de nuestros estudiantes se están recuperando de una agresión o algún otro trauma debido a la violencia interpersonal. Creamos una comunidad de apoyo libre de juicios en cada clase, lo que permite a los estudiantes enfrentar sus miedos con valentía y con el apoyo de sus compañeros.
