Her social work career has focused on the treatment of emotionally and behaviorally disturbed children and youth for the past 30 years.  She co-developed the full IMPACT course for teen girls.​

​“To me IMPACT courses have always been about freedom to live in the world in a more complete and visible way. Providing this experience to women is a revolutionary act – revolution of old restrictive attitudes and beliefs in favor of greater freedom.” – Margaret

Martha

"My belief that ordinary women can do extraordinary things is continually affirmed in teaching IMPACT. We create an opportunity for women to recognize the power, fighting spirit, and love of life they already have." – Martha

Rachel
Rachel began volunteering with IMPACT Chicago in 2014 and became an instructor a few years later, and has been involved in violence prevention, healthy relationship education, and sexual assault policy reform since 2008.

AC
AC is the newest member of the IMPACT Instructor team. He is a certified Rape Prevention and Self Defense Instructor with the American Women’s Self Defense Association, and has worked internationally with Peak Potentials and Success Resources, assisting and leading motivational camps that incorporate martial arts and non-verbal tactics to de-escalate and/or end conflicts without compromising one’s safety or integrity of self (2013-present). He is an Elite-level personal trainer with Chicago Athletic Clubs, a professional actor, and one of the founding members of Not In Our House: Chicago, an organization created to combat sexual harassment and unbecoming conduct within the Chicago theatre community (2015-present). 
​
"In addition to preventing incidents of sexual assault, IMPACT empowers women, allowing them to establish firm boundaries and belief in themselves. Empowered women pave for the way for future empowered women, creating a more female-friendly society, work force, etc." - AC
​
​Ben
Ben got his start in security bouncing for 9 years at bars and clubs in Madison, WI then Chicago. He was a wrestler for 12 years in folkstyle, freestyle, and Greco Roman. He also studied Jiu-Jitsu and other martial arts. He started with IMPACT Chicago in 2004. After  talking with women in his family, he decided IMPACT was the thing to do. He became an IMPACT:Ability Instructor in 2017. Ben is also a tattoo artist.

"I like IMPACT because we teach women how to defend themselves. What we teach is not frilly – the idea isn't to look good, the idea is for them to walk away safely."  – Ben

Rob
Rob has been an IMPACT instructor since January 1999 and is also an Instructor Trainer. He became an IMPACT:Ability Instructor in 2017. After moving to Chicago in 1995, he became involved in rape-prevention training as well as awareness, outreach, and education, working with Rape Victim Advocates and student groups on college campuses. He really enjoys working with and teaching women's self-defense, particularly in the areas of violence demystification and boundary setting. These two areas are often the more misunderstood and least publicized part of self-defense, as well as being more transferable to other life situations.

Joe (in training)
Joe was introduced to IMPACT in summer of 2018 and is proud to be part of this organization. The phrase "One day 'no' will be enough, but until then there's IMPACT" resonated with him so much he was moved to join the team. Joe has been motivated to work with IMPACT as a way to stand up for the rights and humanity of people targeted because of their gender, race, sexual orientation, immigration status, etc.  He is also a voice actor and can be heard in many commercials, apps, toys, and video games.  

"I wanted the opportunity to make real change in an idea I believe in. IMPACT has presented me with an opportunity to immerse myself fully in a cause I think is worth fighting for." - Joe
