From his site:
His experiences on the front lines of law enforcement have led Jon to seek new ways to protect children from predators. His research and passion led him to create the wildly popular children's book: The Swimsuit Lesson. Beautifully written and illustrated, The Swimsuit Lesson helps parents talk to their young children about privacy, modesty, and those who might do them harm. The book has been featured on ABC's Good Morning America, numerous local media outlets and even caught the attention of the Oprah Winfrey Show. Jon has written articles on child sexual abuse and prevention for Focus on the Family, Children's Ministry Magazine, and other publications. In addition to his international speaking audiences, he has become a very popular speaker for local MOPS (Mothers' of Pre-Schoolers) groups.The Swimsuit Lesson has been a simple, effective tool to instruct our kids on appropriate touch and to make them wary of sexual predation. My kids love the beautiful watercolor illustration (by another dear friend Scott Freeman) and they understand the simple message. I highly recommend it.
