He was the middle child to Frank and Agnes Froese with sisters Dorothy (elder) and Patti (younger).

At 16 Froese made his Ontario Major Junior Hockey League debut for his hometown St. Catharines Blackhawks, having been protected as a homegrown player instead of entering the OMJHL draft.

Due to the Blue's financial woes, Froese was not offered a contract out of junior, but instead signed for the Saginaw Gears of the International Hockey League.

Halfway through his rookie IHL campaign, Froese was loaned to the Milwaukee Admirals, where he led them to a playoff berth.

In the 1984–85 playoffs, Froese made 1 start and came in 3 times in relief as the Flyers went to the Stanley Cup finals.

At the close of this season he shared the William M. Jennings Trophy (for backstopping the team that gave up the fewest goals) with Darren Jensen.

After appearing in only 3 games for the Flyers that season, he was traded to the New York Rangers on December 19, 1986, for Kjell Samuelsson and a second-round draft pick.

[2] Following his trade to the Rangers, Froese became half of one of the best tandems in the NHL along with the man he lost the Vezina Trophy to the year before, John Vanbiesbrouck.

[3] Following the season and the Rangers' early exit from the playoffs, Froese went to the IIHF World Championships in Vienna, Austria, where he shut out the Soviet Union during a 0–0 tie.

Following his career, Froese joined the New York Rangers coaching staff as their goaltending consultant, working primarily with young prospects Mike Richter and Corey Hirsch.
