Ph.D. (all but dissertation)
In the classroom, Rieger uses the life experiences he gained (working in what he tells his students is "the real world") as examples when teaching about ancient and American history, while also showing students how today's world was influenced by the decisions of ancient peoples and our forefathers. Rieger also uses writings from people of faith integrated into his lectures, so students can see the working of Christ in our world and history.
Rieger's academic interest lies in the field of the American West, and he has written and presented papers regarding western movies stars from the silent movie era, as well as, concerning Oklahoma's image as perceived inside and outside the boundaries of the state. Additionally, his interest is in Native American culture and history, especially during the Indian wars after the American Civil War.
Rieger received his B.S. and M.Ed. from Phillips University in Enid, Oklahoma. He has completed all course work for the Ph.D. in history at Oklahoma State University and completed the Teaching Effectiveness Training Program at Oklahoma State University. In addition to teaching at Oral Roberts University, Rieger serves as faculty advisor for Phi Alpha Theta. He is a member of the Organization of American Historians and the Oklahoma Historical Society.
