Chris Massoglia was born in Minneapolis, Minnesota, to Christopher and Karen Massoglia. His father is a chiropractor and his mother a homemaker. His parents are devout Christians and Republicans, and Massoglia grew up a fan of Christian popular music (as well as unable to listen to rap music).
Gifted with an above-average intelligence, Massoglia was homeschooled by his mother.
He also had studied jujitsu, played piano, trained as a hip-hop dancer, knew American sign language, and rode horses.
While his peers were taking third grade-level subjects, Massoglia was taking eighth grade-level courses. By the age of 13, he had enrolled in an online university where his coursework included developmental psychology, Biblical studies, algebra, and American history. He was also a stand-out Little League Baseball player.
The Massoglia family has, as of 2009, refused to move to Hollywood, preferring to maintain a home in Minneapolis despite the extensive travel for Chris that this requires.
He began attending acting workshops at a dancing academy in his home town of Minneapolis while in middle school, and auditioning for television commercials by creating home-made audition tapes. His first jobs included commercials for Target, Marshall Field"s, Pepsi Cola, and Best Buy.
He began acting in 2003 under the name "Chris Kelly" (sometimes appearing as "Chris J Kelly") in an episode of the television program Law & Order: Criminal Intent. The same year, he was considered for the part of 10-year-old Sean in the Nicole Kidman film Birth, but the family refused to allow him to appear naked on screen with a nude, grown woman.
He auditioned for Spider-Manitoba 2 (getting far enough in the casting process to spend an afternoon with Tobey Maguire) and Bad News Bears (he returned six times for call-backs but was not cast).
He appeared in two episodes of Medical Investigation in 2004, and four episodes of the TNT cable television police drama Wanted in 2005. He began using his family name of Massoglia in 2008. He made his feature film acting debut in 2007 in the motion picture A Plumm Summer, but his most prominent role as of 2009 was as "Darren Shan" in the 2009 film Cirque du Freak: The Vampire"s Assistant.
Originally scheduled to debut in theaters in 2010, the film was moved to October 2009 to "capitalize on the Halloween season", and opened a month prior to another highly anticipated vampire picture, New Moon.
His follow-up project was the 3-Doctorate horror film The Hole, directed by Joe Dante, He also went on to play the role of older Sam, Zac Efron"s brother in Charlie Saint Cloud, but his role was cut from the film. As of November 2009, most critiques of Massoglia"s acting have concerned his leading role in Cirque du Freak: The Vampire"s Assistant. who ably carries the film.".
He spent the summer of 2004 away from auditions to play Little League Baseball. His team (the Robbinsdale All-Stars) won the Minnesota state title that year but did not go to the Little League World Series after losing in the Indianapolis regionals. His performance has not won raves. Motion picture industry trade publication Variety said, "The production puts far too much faith in the appeal of newcomer Chris Massoglia, who plays Darren Shan, a rule-abiding, good-grade-earning conformist with the shaggy coif and bland, gumdrop charm of your average Nickelodeon character." The Boston Globe called his acting "too bland to deliver." However, in his 2009 film The Hole, The Hollywood Reporter called Massoglia "a young Zac Efron.
