Early life

D'Agosto was born in Omaha, Nebraska, the son of Deanna Rae (née Vellinga) and Alan D'Agosto, Omaha's major Arby's restaurant franchisee. His mother is from Sioux City, Iowa while his father is from Omaha.

On D'Agosto's paternal side, his family is of Italian descent. His maternal grandfather's relations were born in Iowa and Illinois and were of Dutch descent, while his maternal grandmother's relations were born in South Dakota and Wisconsin. D'Agosto is the middle of five children. He has two older brothers, Andrew and Patrick, and two younger sisters, Julie and Katie.

D'Agosto was raised Roman Catholic and selected Genesius of Rome, the patron saint of actors, as his confirmation name. D'Agosto said that he wanted to be a priest when he was young, then when he was 10 years old he started getting into improv.

D'Agosto was very involved in drama and theatre growing up, acting in many different plays and musicals. He participated in competitive forensics speech tournaments during sixth, seventh, and eighth grades. He graduated from Creighton Preparatory School in 1998 and attended Marquette University, where he graduated cum laude in 2002 with a double major in history and theatre.

Career

D'Agosto's big break came when he was cast as the ethical committee chairman Larry Fouch in the dark teenage comedy Election (1999), while he was still a senior at Creighton Prep. The film was written and directed by Alexander Payne, another alumnus of Creighton Prep. D'Agosto starred in the film Psycho Beach Party (2000) while still in college. In 2002, he moved to Los Angeles to pursue a full-time acting career.

He landed guest appearances on primetime television series such as Boston Public, ER, Six Feet Under, Cold Case, House, Supernatural, and Without a Trace. He appeared in three episodes of The Office. He also played West Rosen on the series Heroes.

To prepare for the film Fired Up!, D'Agosto spent three weeks at a cheer camp and worked with a professional choreographer. He also starred in From Prada to Nada with Camilla Belle, which is loosely based on Jane Austen's Sense and Sensibility. In 2011, he starred as Samuel "Sam" Lawton in Final Destination 5.

D’Agosto often returns to the theatre. Among many plays performed during college in Milwaukee, D’Agosto had originated, as well as dramaturged and performed, the play Chomsky 9/11, based on Noam Chomsky’s post-9/11 writings with the late avant-garde troupe, Theatre X. Recently, D'Agosto joined the A2 Ensemble of Los Angeles’ classical theatre troupe, the Antaeus Company.

In Fall 2012, D'Agosto played the role of Tony Kirby in You Can't Take It with You.

As of 2013, D'Agosto is co-starring in Showtime's Masters of Sex as obstetrician Dr. Ethan Haas, fictional protégé of pioneering sex researcher Dr. William H. Masters (of Masters and Johnson fame). His character is a composite of two of Masters' actual associates.

To prepare for the part of Dr. Haas, in addition to reading the biography that Masters of Sex is based on, D'Agosto read The Fifties by David Halberstam. He also watched movies from the 1950s and documentaries on journalist Edward R. Murrow, which had a lot of "individual footage of interviews with these sort of everyday people from that time period."

D'Agosto appeared in the series How I Met Your Dad, as Frank, a love interest of the main character, played by Greta Gerwig. He was cast in early October in the role of Harvey Dent in the television series Gotham.
