Terry Reardon was an extremely bright prospect who potted 32 points in 16 games with the St. Boniface Seals junior club before jumping to the Brandon Wheat Kings in 1937-38. In his next 16-game campaign, he led the Manitoba Junior League in scoring with 29 goals and 16 assists.
In 1938, he joined the Boston Bruins organization, splitting his first three seasons between Hershey of the AHL and the Bruins. Having experienced only limited success in Beantown, Reardon was loaned to the Montreal Canadiens where he was united with his younger brother, future Hall of Famer, Kenny Reardon. The union sparked the older Reardon's best season, netting 19 goals and 19 assist in 36 games.
With the outbreak of World War II, however, his NHL momentum was cut short as he entered military service in 1942 and remained there for the duration of the war.
In 1945, Reardon resurfaced with the Bruins, playing two seasons before concluding his on-ice career in the AHL with the Providence Reds in 1955. He then stayed on as a coach and general manager in the Bruins chain.
