O'Neill grew up in Montgomery, Alabama and graduated from Auburn University in 1974.[1] After attending Auburn, he spent time under the tutelage of actor Will Geer and one of Geer's daughters, the actress Ellen Geer, at Theatricum Botanicum in Los Angeles before moving to New York to pursue his career there.
With a career stretching through three decades, he usually portrays senior law enforcement or military officers.[citation needed] He is perhaps best known[citation needed] for his role as Special Agent Ron Butterfield, the head of President Josiah Bartlet's Secret Service detail, on The West Wing. He played CTU Administrative Director Richard Walsh in the first two episodes of 24. He played Sgt. Maj. Ron Cheals in CBS' action drama series The Unit. He starred in the Season 6 two-part finale of Grey's Anatomy as the broken widower who holds the hospital hostage with a 9mm while pursuing the doctors responsible for unplugging his wife. His most notable film performances occur in Seabiscuit, Secondhand Lions, Transformers, Dancer, Texas Pop. 81, Traffic, Sea of Love, A Quiet Little Marriage, Nothing but the Truth, and Green Zone.
