Berry joined the then Fighting Sioux in 1983, playing in a limited role in his first season. For his second year with North Dakota Berry saw his points total more than triple and was included on Canada's world junior team that won a gold medal. Unfortunately the Fighting Sioux slipped to fourth place in the standings and weren't able to earn a bid into the NCAA tournament. After another year with a similar result Berry forwent his senior season and turned pro with the Winnipeg Jets who had drafted him in the second round of the 1983 draft. In doing so, Berry missed out on North Dakota's National Championship the following year.
