After coaching Wittenberg's record-setting receiving corps from 1996-2005, Mark Ewald took over the running backs coaching duties in 2006. He has become a key contributor to one of the top offensive units every year in NCAA Division III.

Almost every Wittenberg receiving record was broken under Ewald. Among his proteges were all-conference standouts Michael Aljancic, Skip Ivery, Russ Fedyk and Jered Glover. In 2006, Ewald coached NCAC Player of the Year Tristan Murray, the No. 2 rusher and scorer in Wittenberg history. The Tigers' passing game regularly ranked among the best in the NCAC and all of NCAA Division III during his tenure there and the running game in recent years has been no different.

Before joining the Wittenberg staff, Ewald was an assistant coach at nearby Trotwood-Madison High School after three years as head coach at Carroll High School in Dayton. He also coached at Chaminade-Julienne High School for several years. Ewald resides in Kettering, Ohio with his wife, Diane, and three children, Nicholas, Jacklyn, and Luke David.
