Clohessy was born in the The Bronx, the son of John Clohessy, a police officer. Clohessy graduated from SUNY Purchase, along with Oz co-stars Edie Falco, Kirk Acevedo, and Seth Gilliam. Clohessy fought in the 1975 Golden Gloves in Madison Square Garden. He graduated from Pearl River High School in Pearl River, New York where he played varsity football. Clohessy first appeared on stage at Pearl River High School in their class production of Guys and Dolls, playing, of all things, a police officer.
Clohessy has had recurring roles in daytime dramas All My Children and Guiding Light. In primetime, he has become known for his multiple regular turns as police officers and other law enforcement officials, creating parallels between his acting career and upbringing by his policeman father. The first of such roles was in the seventh and final season of Hill Street Blues, where he played Officer Patrick Flaherty. The following season, Clohessy was cast as the new co-star of Pat Morita on the ABC detective series Ohara, playing Lt. George Shaver. Later, he would join the cast of the HBO prison drama Oz as Correctional Officer Sean Murphy. However, in between these roles, Clohessy would play characters not associated with law enforcement, with a supporting role as minister Thomas Smaraldo on NBC's comedy/drama Tattingers (1988–1989), and soon after in a starring role on NBC's short-lived comedy One of the Boys (1989). Clohessy co-starred on the Neal Marlens/Carol Black ABC sitcom Laurie Hill in 1992, playing a stay-at-home freelance writer married to the series' lead, played by DeLane Matthews (the series also featured an up-and-coming Ellen DeGeneres). In 2008, Clohessy had a regular role in the short-lived Fox show New Amsterdam.
In cinema, Clohessy played a semi-minor role in Across the Universe, playing the part of Jude's long-lost father. His starring role as boxer turned wrestler, Jack Parker, in the film The Crimson Mask garnered him numerous film festival awards including Best Actor 
Clohessy played the role of "Mike" in the Broadway Roundabout Theatre Company revival of Pal Joey, from November 2008 through February 2009. He is currently seen on HBO's Boardwalk Empire, and has a recurring role on the CBS crime drama Blue Bloods as Sgt. Gormley.
