Gina Santoro, in the picture above says; as young girls, we are told “not to fight,” but to be "Lady like and gentle." Perhaps one of the disadvantages to our social upbringing is the lack of instinct women need to fight back. In all animal species, the females are the protectors. Except in humans! That is why women are preyed upon; they are seen as the weaker ones.

Let’s change that! Come & learn Self Defense & make it an instinct!

Statistics show, 1 out of every 3 women are victims of assault or rape. We will show you how not to be that 1 out of 3 at this course! Don't be one of the statistics!  Learn how to protect yourself & your family!

Appropriate age to learn self-defense against predators: From the age of 8 to 80 - Everyone should learn how to defend themselves!

At this workshop we are going to focus on what to do when an assailant is trying to attempt some of the most common attacks statistically that women have had problems with in the past from a strong and angry individual. Knowledge in self-defense for this area is very important to prevent the worse in what could possibly take place. Prevention is the best medicine and women who are learning good self-defense nowadays is the medicine absolutely no one will want to be on the receiving end of! Don’t be a victim…sign up today!

You will not want to miss out on the valuable information offered at this workshop! Come learn how to defend yourself at the Practical Self Defense Training Center!
