Meet Our Staff & Board


Our Staff

Impact Bay Area staff are Certified Impact Self-Defense Instructors, who have each completed over 150 training hours in full-force self-defense techniques. Our instructors are versed in physical, verbal and sexual abuse/assault awareness and prevention. We are committed to ending violence by sharing Impact's empowerment and self-defense classes with as many people as possible.

Our full-force courses are team-taught by a "Whistle" Instructor and a "Suited" Instructor. They work together to provide a comprehensive experience for our students.

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 fights.

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

 Jenny Williams

Jenny is a martial artist who took her first Impact class in 2001. She was impressed at the sense of empowerment and the healing that she gained from that class. It offered so much more than any other self-defense class or seminar she had experienced.

Jenny became a certified Impact Bay Area instructor in 2008. With every class she teaches, Jenny feels honored to witness the courage and power that each student brings onto the mat.
