David and Leslie Nunnery are the founders of Teach Them Diligently and the parents of four children who range in age from 15-22. God has given them a strong burden to minister to Christian families to help support, encourage and equip them to disciple their children, protect their marriages, and serve God in the ways He has planned for them. They are advocates of home education with a strong focus on discipleship which is evidenced in their writings and the events their family produces. They are authors of countless articles as well as several books and courses. They are also heavily involved in mission endeavors through Worldwide Tentmakers, for which David serves as president and Teach Them Diligently supports.
