Mark Gregston
Mark Gregston began his work with teens forty years ago when he was a youth minister and then an area director with Young Life. He and his wife Jan opened their home to work with those who were struggling through family crises, and in 1989, Mark and Jan moved with their two children, Adam and Melissa, to Hallsville, Texas. Here they started Heartlight, a residential counseling center for struggling teens and families in crisis. They are the proud grandparents of four: Maile, Macie, Chase, and Carter.
