Adduono embarked on a pro career by playing three seasons with St. Catharines in the OHA, 1972-75. In his second year, he led the league in assists and points, with 84, in a year he scored 135 points, and he looked to be one of the better prospects for the NHL.
However, Adduono was hampered frequently by injuries during his final season of junior and his stock dropped by the time he became draft eligible. He was selected 60th overall by Boston in 1975 but played only one game for the Bruins during the '75-'76 season as a callup from the farm team in Rochester. After two more years with the Americans, he joined Birmingham in the WHA and returned to the NHL for three games with Atlanta in 1979-80.
His NHL career clearly over, Adduono played in the minors and briefly in Austria before turning to coaching, culminating with his being named head coach for South Carolina in the ECHL in 1998.
