Mark Atteberry was born and raised in Santa Rosa, California, where he worked on the family dairy farm before moving to Los Angeles to become an award-winning actor, musician, and photographer. He began his work in the entertainment industry as a studio musician, playing trombone, tuba, and keyboards. In that capacity he played in countless orchestra pits, where he first caught the acting bug.

Moving into acting, Mark studied with many leading acting teachers, including Roy London, Ivana Chubbuck, Larry Moss, Howard Fine, and Vladimir Ilyin of the Moscow Art Theatre. Mark's film work ranges from blockbusters such as David Fincher's Gone Girl and Ang Lee's Hulk to notable independent films such as The Future, The Butterfly Circus, and Tainted (for which he received his first nomination for Best Actor). Mark's television work includes such hits as The Newsroom, Bones, Grey's Anatomy, Criminal Minds, Luck, Dexter, House, Rules of Engagement, The Closer, The Mentalist, Justified, Big Love, The Shield, The Young and the Restless, 24, Nip/Tuck, and many others.

As a photographer, Mark is known for his advertising, documentary, and portrait work. His clients have included A&E, Bravo, CAA, ICM, WME, Venice Magazine, Big Lots, and many others. When he first began shooting professionally, Mark was selected by BackStage West magazine as one of the "best portrait photographers in Los Angeles." And in 2010 he was honored by the Photography for Social Change Foundation as one of the "100 best documentary photographers in the world."

As a result of countless hours on both sides of the camera, Mark sometimes speaks and teaches on the topics of "Image and Type" and "Acting in Los Angeles." He is the co-author of several books on acting, including The Working Actor's Guide to Los Angeles and The Stunt Guide. Mark is the founder of Be A Working Actor Studios in Los Angeles.
