A graduate of Cathedral High School, Shrewsberry began his coaching career in 1999 as a graduate assistant at the University of Indianapolis. After stints as an assistant coach at Wabash College (2000-01) and DePauw University (2001-03), he spent the 2003-04 and 2004-05 seasons as director of basketball operations at Marshall.
The two seasons prior to his arrival at Butler saw Shrewsberry serve as the first-ever full-time head coach at IU-South Bend.
Shrewsberry was a three-year starting guard at Hanover during his playing career, serving as a tri-captain as a senior in 1998-99. He led the Heartland Collegiate Athletic Conference in free throw shooting (.833) and assists (4.4 apg) in his final campaign.
