Davis and Rachael were married in 1986, and God has blessed them with seven children and one grandchild; so far, three children have graduated from their home school. They live in Waxhaw, North Carolina, where they enjoy the homeschooling adventure of a lifetime, complete with roller-coaster twists and turns and the occasional lazy river ride. Davis is an international speaker and advocate for home education; he has a degree in mechanical engineering from Vanderbilt University and a master’s degree from Purdue University. Davis is also the author of three illustrated children’s books designed to instill a biblical worldview: Good Morning, God, A Light for My Path, and In the Beginning. Rachael is a speaker and the author of How Many Times Do I Have to Tell You? and How to Have a HEART for Your Kids, where she challenges mothers to surrender their will and draw closer to their heavenly Father. Together, Davis and Rachael own Apologia Educational Ministries, the #1 publisher of Creation-based science and Bible curriculum. In his role as president of the company, Davis’ mission is to help homeschooling families learn, live, and defend the Christian faith.
