Daniel Cosgrove seemed destined for a career in anything but acting as a child. The New Haven, Connecticut native was extremely shy, growing up. However, upon attending an all-boys Catholic high school, he began pondering a future in show business.

"When I was thinking about what I was going to pursue in college, I thought wherever I went, I want to get involved in some sort of drama department," notes Cosgrove, who ended up taking an improv class at a small college. When some seniors asked him to appear in a play, Sorry, Wrong Number, Cosgrove said yes and was hooked.

"I loved it," he says.

Ultimately, Cosgrove decided to take a break from his studies. He began commuting to New York for weekly classes and tried his hand at modeling for a bit.

In 1995, he moved to New York. Within six months Cosgrove got his big break: the role of Scott Chandler on . He left the soap in 1998, moving onto primetime, when he landed the part of Matt Durning on Beverly Hills, 90210.

Cosgrove segued to movies in 2000, appearing in They Crawl and Van Wilder, and also won a job on the primetime series All Souls.

By 2002, he was back on daytime; this time portraying Bill Lewis III on . In 2010, he joined the cast as Chris Hughes, before returning to All My Children for another run. He surfaced on Days of Our Lives as protective father Aiden Jennings in 2014, but was killed off the show in 2015, when Bo found him trying to strangle Hope.

Cosgrove currently resides in Los Angeles with his wife and their four children.
