ALLIANCE, Ohio — Larry Kehres, who turned Mount Union into a Division III powerhouse while stockpiling 11 national titles, is stepping down.

Kehres, 63, had a remarkable 332-24-3 record in his 27 seasons with the Purple Raiders. His teams were unbeaten in the regular season 21 times. The national championships came in 1993, 1996, 1997, 1998, 2000, 2001, 2002, 2005, 2006, 2008 and this past season.

His .929 winning percentage in all games is the best ever at the college level.

He will continue as Mount Union’s athletic director. Kehres did not specify why he was stepping aside as coach, but he will be replaced by his 37-year-old son Vince, who is taking over the job after a resume which parallels his father’s.

The elder Kehres, in his 39th year working at his alma mater, began working as an assistant football coach and professor in 1974. He was Mount Union’s first head swimming coach and was hired as athletic director in 1985.
