Impact Instructors

Ready_Stance.jpgImpact 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

 JennyDojo100x157.jpgJenny 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. This class had such a positive influence on how she lived her day to day life that decided to become an assistant. She 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.    





Heather took her first Impact class in September of 2008. She had such an empowering and transformative experience that she became an instructor assistant a few months later. She served as the Coordinator of Assistants for three years, helping to ensure that all of our classes had volunteer assistants to support our instructors and our students. Heather has logged more hours volunteering for Impact than any other individual, and we're deeply grateful. She was certified as an instructor in 2012.

Cheryl Porter, Assistant Coordinator

Me_2010.jpgCheryl began volunteering with IMPACT Bay Area after taking the Women's Basics course in February, 2011.  The empowerment, compassion, support and empathy she experienced from the course training, her classmates and especially the instructors and assistants motivated her to provide the same experience to others. Cheryl volunteers for IMPACT because she wants everyone to be able to experience the same joy and empowerment she received from IMPACT and to also provide support to an organization that she believes is truly making the world a better place by helping individuals find their own inner strength and empowering them to reach out and help others, too.
