Soon after graduating from high school in Tampa, Florida, Broderick flew to New York in the early 1970s to compete in DC Comics' junior bullpen program, a nationwide art and writing contest held at the July 4 convention at the Commodore Hotel.

[2][3] During this period, Broderick also worked for Neal Adams and Dick Giordano's Continuity Associates as a member of the Crusty Bunkers.

His time at Atlas was short-lived, and Broderick soon found himself back at Marvel, working on various titles for their black-and-white line, Curtis Magazines.

[11] Captain Atom, a Charlton Comics character purchased by DC, was given an ongoing series in March 1987 which was written by Cary Bates and drawn by Broderick.

[15] In 1995, Broderick turned to advertising full-time, moving to Dallas to lead the in-house creative department at Tracy Locke and Partnership.

The company handled packaging, print, and television ads for PepsiCo, Frito-Lay, Pizza Hut, Federal Express, Harrah's Casinos, and Hasbro.

[16] That same year, Broderick was a member of the animation department faculty at Tampa's International Academy of Design and Technology.
