Mark Gregston is the host of the popular radio program, Parenting Today's Teens, heard on over 2,500 radio stations, and has authored several books to help parents prepare for and survive the often-turbulent teen years.  A popular speaker and seminar leader, he blends humor and storytelling with Biblical insights for parents who desire a deeper relationship with their teen.  Mark's background as a youth pastor, a Young Life area director, and the founder of Heartlight Ministries (a residential counseling center for teens), coupled with his passion for helping parents caught in difficult situations, provides the foundation from which he speaks.  His effectiveness is grounded in a practical approach and the lessons learned from years of having 50 struggling high school kids live just beyond his back door at Heartlight.  Mark has been married to his wife, Jan, for 36 years.  Together they have two grown kids who are each married, two grandkids, one dog, one cat, and too many horses.  To learn more about Mark and his ministry to parents and teens, please visit www.MarkGregston.com
