Davis and Rachael were married in 1986, and God has blessed them with seven children (five of whom have graduated from homeschooling) and one grandchild. 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. 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.
