Catherine was sexually abused by her step father and held  to secrecy not only by him but by her mother. For 11 years she was viciously attacked on a regular basis. Catherine reported her abuse to family members and friends. Every time she used her voice to protect herself she was made out to be a liar. No one listened, no one helped her. She stopped using her voice for a very long time.

Catherine's voice was taken away and it is her heart and her mission to give every child a right and the privilege to use their voice to protect themselves.
