Michael C. Maronna was born in Brooklyn, New York, as the oldest of three children, and began his acting career at the tender age of five.
He attended public schools in Brooklyn and Queens while working on various projects, including commercials, soap operas, and eventually Broadway productions.
Michael was cast in the Nickelodeon TV show "The Adventures of Pete & Pete" in 1989, initially as a 60-second show between cartoons, and went on to appear in the films "Home Alone" (1990) and "Home Alone 2: Lost in New York" (1992) as Jeff McCallister, Kevin's mean brother.
The show "Pete & Pete" began full production as a series in 1993, with Maronna in the title role, and aired on Nickelodeon for three seasons.
After graduating from Manhattan's City-as-School, Michael began working as an electrician on films, with his first job being on the film "Six Ways to Sunday" (1997),which was directed by "Pete & Pete" alumnus Adam Bernstein.
Michael attended SUNY Purchase in Westchester County, where he studied documentary filmmaking in the Theater Arts and Film Conservatory from 1997 to 2001.
During his time at SUNY Purchase, he appeared in several popular Ameritrade commercials in 1998 and 1999, which led to an appearance with President Adam Bernstein in a White House Correspondents' Dinner video in 2000.
After graduating, Michael played Jeff in the film "Slackers" (2002) and had a memorable turn as the Bagel Guy in the feature film "40 Days and 40 Nights" (2002).
