After college, Dan went to work for a Christian mission organization working in agriculture. During this time, through the faithful preaching of a local church, he found himself embracing the teaching of the doctrines of grace. Shortly thereafter, Dan met his wife Mary Lee through a mutual friend who played “matchmaker.” They now have four children who have attended Cornerstone, with the oldest having graduated in 2019. Dan has a doctorate in agriculture science and is an expert in environmental issues related to agriculture. In his spare time, Dan likes gardening, travel, and reading.
