At Cairn University, Dr. Keith Plummer teaches on a variety of topics related to pastoral ministry, including pastoral care, pastoral practice, and pastoral counseling and community building.  He also teaches on apologetics, spiritual formation and disciple-making ministries, and ministry in a cultural context.  Biblical courses he teaches include Introduction to the Bible and Exposition of the Pastoral Epistles.

Before teaching at Cairn, Dr. Plummer served as associate pastor at Our Saviour Evangelical Free Church in Wheeling, IL, for 17 years.  Exercising his strong interest in radio and podcasting, he also once conducted a series of interviews with Christian authors–an endeavor he would like to resume again someday.
