Self Defense Classes & Workshops
Define Defense has carefully selected techniques and methods to create a separate self defense program that is specifically designed to keep you safe. It is our goal to teach you the very best skills without giving you a feeling of false confidence. We teach all levels and ages.
In our self defense classes, you will learn:
- Self defense against weapons (knife, stick, handgun)
- Self defense on the floor against a standing attacker
- Self defense against sexual assault
- Self defense against grabs, chokes and other forceful attacks
- Effective striking
- How to avoid dangerous situations
- How to maximize your chances of escape
- How to use pepper sprays (and other defense sprays)
- Vital points, body language and other proven methods to get yourself into safety
Remember, martial arts is NOT the same as self defense, that is why we have created a separate program and curriculum!

- I thought it was pretty cool that he pushed us to take it to the next level. And maybe I wouldn't have the perfect form, but if I were attacked, it expanded my mind's possibilities of what I could do to escape.
Bottom line: I felt empowered. And that's probably the most important step of self-defense -
