Childhood & Early Life
David Gallagher was born David Lee Gallagher, on February 9, 1985, in College Point, New York, US, to Elena and Darren James Gallagher. His mother was Cuban, while his father was Irish. The couple separated when David was still a baby.
David then began living with his mother, who later married a man named Vincent Casey. David grew up with four half-siblings: Michelle, Kelly, Kyle, and Killian.
He later moved with his family to Los Angeles, California. He attended ‘Chaminade College Preparatory School,’ from where he graduated in 2003. Living in Los Angeles, David had caught the acting bug and soon started appearing in ads, commercials, films, and TV series.
In order to know about the filmmaking process in detail, he enrolled at the ‘University of Southern California’ and majored in film & TV studies, graduating in May 2007.

His mother sent out his photograph to various modeling agencies when he was 2 years old. Not too long after that, little David bagged his first modeling assignment, which was for a print advertisement. Following this, he appeared in advertisements for renowned brands such as ‘Walt Disney,’ ‘Burger King,’ ‘Panasonic,’ ‘Hanes,’ ‘Tyson Foods,’ and ‘Betty Crocker.’
As he grew up, he gradually became a somewhat known face. At the age of 8, David got his first acting project, which was for the supporting role of ‘Mikey Ubriacco’ in the 1993 romantic comedy ‘Look Who’s Talking Now.’ The film got abysmal reviews from critics and was also a major box-office disaster.
In 1995, a 10-year-old David appeared as ‘Stevie Pomeroy’ in the TV film titled ‘It Was Him or Us.’ David then appeared in two more supporting roles, in the TV films ‘Summer of Fear’ (as ‘Zack Marshall’) and ‘Bermuda Triangle’ (as ‘Sam’).
In 1996, David had his major acting breakthrough, with the John Travolta-starrer romance/fantasy–drama titled ‘Phenomenon.’ In this critically and commercially successful film, David played ‘Al Pennamin.’ David was just 11 years old at that time, and this overwhelming success brought him better offers. Soon, he bagged the role of ‘Simon Camden,’ which is still considered to be one of his best roles.
He played ‘Simon Camden’ in the first seven seasons of the drama series ‘7th Heaven.’ He then made a brief appearance in its tenth season, too. David’s role was that of the second son and the fourth child of the leading ‘Camden’ family in the series. The producers wanted him for the eleventh season, too, but David had no desire to play the role anymore, after the tenth season.
His performance as ‘Simon Camden’ in the series ‘7th Heaven’ earned David many accolades. He won a ‘Teen Choice Award’ for his performance in 2003 and was also nominated for the ‘Young Artist Award’ quite a few times.
In the late 1990s, David played voice roles in many series, such as ‘Rocket Power’ and ‘The Wild Thornberrys.’
In 2000, David earned the first leading role of his career when he was offered the role of ‘Marty Markham’ in the TV film titled ‘The New Adventures of Spin and Marty: Suspect Behavior.’
In the early 2000s, he appeared in leading roles in films such as ‘Little Secrets’ (as ‘David’) and ‘Kart Racer’ (as ‘Scott McKenna). In the 2005 film ‘The Quiet,’ he essayed the supporting role of ‘Brian.’

As he got older, the quality of the roles he was offered deteriorated. Soon, he resorted to playing supporting roles in films and TV series.
In the late 2010s, he made small appearances in a number of series, such as ‘Saving Grace’ (as ‘Paul Shapiro’), ‘Bones’ (as ‘Ryan Stephenson’), ‘Without a Trace’ (as ‘Jeff Ellis’), and ‘Smallville’ (as ‘Zan). He also appeared in a low-budget TV movie titled ‘Betwixt.’
In 2011, he appeared in the JJ Abrams-directed science-fiction monster film titled ‘Super 8,’ playing the role of ‘Donny.’ The film was a huge commercial success and also earned some fairly good reviews. The same year, he managed to get a lead role (‘Reid Davis’) in the film ‘Trophy Kids.’
After appearing in two episodes of ‘Vampire Diaries’ in 2011, David appeared in small roles in series such as ‘CSI: Crime Scene Investigation’ and ‘CSI: NY.’ Lately, he was seen playing the supporting role of ‘Brian’ in the TV film titled ‘Born and Missing.’
David has also voiced the character ‘Riku’ in 13 instalments of the successful video game series ‘Kingdom Hearts.’
He has produced the video short ‘Freakin' Zombies, Man!’ and ‘The Picture of Dorian Gray’ and co-produced another short, ‘Mummers.’
He has produced, directed, and written the 2003 comedy ‘Ten Bucks.’
