Real Training

Remember: Violent encounters are sudden, intended to catch you unguarded or off balance. The SHIELD method is for real-life situations. We believe the proper training to defend yourself and your loved ones should resemble exactly the things you want to protect them from.

By combining the instinct to survive with honing real-world techniques to combat violence, the SHIELD self-defense program will better equip anyone, regardless of skill level or experience, to feel more confident and possess better situational awareness.
