Allison took the reins of a Sheridan men's basketball program that had been building towards more success in the late 70s, but found a way to elevate it to new heights.
His first two seasons at the helm were very much about building, but by his third season the Bruins were now officially a threat, finishing as the OCAA runners-up and garnering the school's first appearance at the national championship, where they finished fourth.
In 1984-85, Allison would guide the Double-Blue to the top of the mountain by claiming the first OCAA and CCAA Championships in team history, claiming the latter by an average victory margin of 13 points.
During his career, he compiled an overall record of 332-200, while winning 70 per cent of his OCAA conference games (188-82).
He won four OCAA Championships, two CCAA Championships, three regular season OCAA Division Championships and added a CCAA Silver Medal in 1985-86.
