Living in Los Angeles since 2005, Mark has worked many series and had the opportunity to get featured in a good handful of them by directors. He began appearing on TV as a CBS Page at The Price Is Right, clapping and giving high fives to contestants as he guarded Bob Barker's stage during his final season in 2007, and also worked his final show. Since 2009, Mark has worked on several series as an extra and was picked several times to be featured, becoming more than just a background blur in far back scenes or basic crossing scenes, as he was used in shots which featured on only him. These are screencaps of Mark when he worked as a Page at CBS at The Price Is Right and when he was featured on TV series including Glee, Desperate Housewives, Men of A Certain Age, Greys Anatomy, The Defenders, and Don't Trust The B-In Apartment 23. Mark, in his featured character parts in TV shows, has interacted with actors such as Matthew Morrison (Will Schuester on Glee), Eva Longoria (Gabrielle Solis on Desperate Housewives,) Sarah Drew (April Kepner on Greys Anatomy), Sandra Oh (Cristina Yang on Greys Anatomy), and Brian J. White (Marcus on Men of A Certain Age) and Patrick Gallagher (Jesse on Men Of A Certain Age).
