I am the mother of two daughters and each of them participated in training with Impact Bay Area before they went to college.
My youngest daughter attended her first group training in middle school, an event I organized for her girl scout troop. After her experience I felt my oldest daughter must have this experience before she went off to college. Neither daughter had had a traumatic experience and there were times I wondered if this was too much exposure. I learned the answer was absolutely, "NO. It wasn't." Here is why: through the training they gained important skills and tools that later they unexpectedly needed. Each had an intense and scary situation, one in high school and one in college. If they had not known how to respond they may have been victims.
So I asked my oldest daughter after she had graduated from college about having gone through the training. She said she was very glad she had completed the training, that even if nothing had happened to her, it had empowered her and gave her confidence she would otherwise not possess. As a parent I feel every young person should know how to take care of themselves, not isolate, and have a sense of power. I can't say enough good things about the training. Also remember males need this training too.
