Mark Sinacori was born on August 16th, 1982 in Lawrence, Mass. He attended the Rollins School, Holy Trinity School, and Central Catholic High School in Lawrence, Merrimack College in North Andover where he majored in English, and moved to Los Angeles in 2005 to attend UCLA's Professional Screenwriting Program. In 2007, Mark became a CBS Page in the CBS Page Program at CBS Television City in Hollywood, and worked on many shows that filmed there on the lot such as Dancing With The Stars, American Idol, The Late Late Show With Craig Ferguson, and The Price Is Right. At The Price Is Right, he always entertained the audience members outside in line, got them to sing to pass the time, and pepped them up both outside and inside the studio. Working at The Price Is Right was Mark's most memorable time out of everything he has worked in Los Angeles in Television and Film. Working there, he was asked to be at the show for many behind the scenes events and special occasions during Bob Barker's final season, including practice run throughs with the potential hosts who auditioned to replace Bob Barker such as Mario Lopez and George Hamilton. Mark had a lot of fun as a mock contestant several different times, working alongside these celebrities as they learned the games. Mark even got to work Bob Barker's final taped show, and while outside getting the audience ready and pepped up, the former producer at the time, Roger Dobkowitz, who was outside visiting the audience in line, commended Mark for always getting the audience energetic and to always cheer for Bob each time he worked the show. Since 2007, Mark's focused on acting, and was not only featured on shows such as Glee, Grey's Anatomy, and Desperate Housewives, but also had starring and supporting parts in several independent films and decided to start making films of his own. Since 2010, Mark has taken an extensive amount of classes for acting, including on camera classes, cold reading classes, and commercial classes. In 2014, Mark got back into working with audiences when he became an audience page again, and has worked in many studios all over Los Angeles including Warner Bros., Sony, Manhattan Beach Studios, and Los Angeles Center Studios, greeting and processing audiences for many different sitcoms and television shows including Mike & Molly, Mom, Two Broke Girls, American's Funniest Home Videos, Girl Meets World, and Fuller House. In 2015 at Fuller House, Mark would create Full House trivia for the audience before the taping, getting them familiar with the original series and ready for the taping of the revival series. Ever since Mark did his Full House trivia at Fuller House with the shows audience waiting in line in 2015, he also did classic TV trivia and other trivia for other shows he's worked on with the audiences in line who attended them. Shows Mark has done TV trivia out in line with their audiences as they waited to enter the studio have included not only Fuller House, but also Undateable, The Ranch, 2 Broke Girls, and Girl Meets World, where he got audiences familiar with the series by doing trivia from both that series and its preceding series, Boy Meets World. In 2018, when The Conners began filming their series at Warner Bros, Mark also began doing trivia for that audience as well based on the Conner family from its preceding series Roseanne.
