He has served in Honduras, Nicaragua, and Central Asia. His area of emphasis is personal discipleship. David and his wife Betsy were commended in 2000 by Fairhaven Bible Chapel in San Leandro, California, to the work of the Lord in Esteli, Nicaragua. While there, David and Betsy hosted three mission schools with the vision of seeing Central Americans sent out to unreached people groups. Eventually, they felt called to lead by example in this effort and went to Central Asia in 2009. David has been involved in teaching at several discipleship programs including Modulos Biblicos in Central America, the Galilee Program in Lafayette, Louisiana and the Discipleship Internship Training Program (DITP) in Lubbock,Texas.
