Tom O’Neill is a writer and editor who has written for daily newspapers (Philadelphia Inquirer, New York Daily News) as well as national magazines and news weeklies (Village Voice, New York, Premiere, Details, Out, Philadelphia, Irish-America, Live, Detour).
As a contributing editor at Us magazine (1991-1999) he wrote cover stories on some of the entertainment industry’s biggest stars (Tom Cruise, Harrison Ford, Richard Gere) while reporting from the sets of hit television shows (Saturday Night Live, Fraiser, Northern Exposure). His first investigative story for Us,  about the cut-throat battles waged by daytime talk-show producers for their guests (“Welcome to the Jungle”), spawned the magazine’s popular investigative series, “The Us Report.” A subsequent story for the series by O’Neill, about the stalking and murder of actress Rebecca Schaeffer by a deranged fan (“Dangerous Minds”), was, in turn, used as the prototype for what would become the now-iconic E! Channel documentary series, E! True Hollywood Story. O’Neill’s investigation into the unsolved slaying of a Hollywood starlet for Details magazine (“The Life and Death of Miss Hollywood”) was also adapted into a True Hollywood Story by the E! Channel and his expose of sexism at Saturday Night Live (“The Incredible Shrinking Woman of Saturday Night Live“) won an Exceptional Merit Media Award from the National Women’s Political Caucus and Radcliffe College in 1995.
Since 1999, O’Neill has been researching a book about one of the most sensational crimes of the last century, the murder of actress Sharon Tate and others by the Manson Family.
O’Neill graduated with a Bachelor in Fine Arts from New York University’s Tisch School of the Arts.
He currently resides in Venice, CA.
