Jacob Stagner, Suited Instructor and Instructor Trainer
In Jacob’s younger years, he was not aware of the fear of being harassed or attacked that follows many women in simple daily activities like going to the store, gas station, or park. As a man, he felt no such anxiety and therefore experienced no limitations in where he could go, even late at night. He simply went about his day, free and at ease. When he found out later, through the women in his life, how restrained they feel by their fear, he was upset. This new knowledge drove him to seek out ways to end this imbalance and help women claim the same feelings of ease and freedom he has experienced as a men. Impact has given him a forum to do that.
Jacob cherishes the opportunity to teach adults and children about safety, awareness and effective self-defense. IMPACT’s skills allow everyone to lead their lives with a greater sense of empowerment and freedom from fear. Jacob has a diverse background in sales and is thrilled to be sharing a “product” he believes in so deeply. In his spare time, he is an avid runner and adventurer.
