Dave Crook was born in Winnipeg, MB. He graduated from Elmwood High School, and then the University of Winnipeg in 1982. In addition to coaching at Elmwood and West Kildonan high schools, he was the assistant coach of the Wesmen men's basketball team under Bruce Enns from 1982-1984. He was hired in 1984 as the head coach for the men's basketball team at Mount Allison University in New Brunswick. He was laid off when funding for the athletics program there was cut in 1989, and moved to the University of Lethbridge, as head coach and instructor, from 1989-2000. University of Lethbridge publications describe him as their “winningest coach.” Due to his performance in that role, he was awarded the Men’s Basketball Coach of the Year by CIS. In 2001 he returned to the University of Winnipeg as head coach of the Wesmen men’s basketball team and instructor until 2010. He resigned as coach (but continued to teach) that year; in 2015, he was made the University’s Athletic Director, in which role he continues today.
