After spending months lobbying Boston Garden treasurer George Clare for a job, Powers was hired as an accounting clerk in January 1929. He moved up the ranks to the positions of vice president-assistant treasurer and then vice president-treasurer. As vice president, Powers was in charge of the Boston Garden when president Walter A. Brown was out of town. On September 16, 1964, Powers was chosen to succeed the late Brown as president and general manager of the Boston Garden.
