Dorey was a defenceman who played for the Toronto Maple Leafs and New York Rangers in the NHL.

[2] The New York Rangers acquired him for Pierre Jarry late in the 1971–72 season, when Maple Leaf management suspected he might be about to jump to the fledgling WHA.

Dorey played just one regular season game with the Rangers before suffering a separated shoulder.

[3][4][5] After his retirement he coached the Kingston Canadians of the Ontario Hockey League.

Dorey ended his career as an Allstate Insurance agent in his hometown, and retired in March 2008.
