Through the years, Mark has lived with over 2,500 teens spending countless hours helping, talking, and connecting with teens while developing materials to help families help their child through their teen years. Dr. Tim Kimmel says of Mark, “Mark Gregston’s never met a teenager he can’t believe in or a parent he doesn’t want to help become better. . . .he has a clear ‘big picture’ grasp of effective parenting. It’s formatted by the power of God’s grace and seasoned from decades of experience.”
From his 38 years of experience of working with teens and their families, Mark shares his insight and wisdom through books, seminars, retreats, and the Parenting Today’s Teens radio program.
