staff.pngIMPACT certified instructors have completed over 150 training hours in full force empowerment self-defense. Our instructors are versed in physical, verbal, and sexual abuse and assault awareness and prevention. We are committed to ending violence by sharing IMPACT's empowerment self-defense classes with as many people as possible.

Our classes are team-taught by a "Whistle Instructor" and a "Suited Instructor." The Whistle Instructor demonstrates physical and verbal techniques, facilitates group discussions, models how to fight back against a mock assailant, and coaches students during their practice fights.

The Suited Instructor wears protective gear and plays the role of mock assailant, allowing our students to practice techniques from verbal boundary-setting to full force blows in realistic scenarios.
