In between his two stints at Lawrence, Krepline served as an assistant coach at St. Norbert College where he worked extensively with the pitching staff for four seasons (2015-2018). During that time, he coached six All-Midwest Conference and four All-Central Region pitchers. St. Norbert College also had the Midwest Conference North Division Pitcher of the Year in three separate seasons he was there. With Krepline on the staff, St. Norbert won three Midwest Conference North Division titles, a Midwest Conference championship and played in the NCAA Division III Regional Tournament.

Prior to starting his coaching career, Krepline played professional baseball for two years with stints on the Lake County Fielders, Macon Pinetoppers, Saskatchewan Silver Sox and Rockford River Hawks.
