Sean Jackson grew up in Santa Barbara, California with a love for performing at an early age. From elementary school through high school, he kept busy refining his talents in acting, impersonation, characters, voice-overs, improv, singing, and dancing, becoming a staple of his school plays and talent shows. At 16, he began studying sketch comedy in Montecito with acting legend John Cleese.

At Santa Barbara City College, Sean was honored with the prestigious Actor of the Year Award in 2006 for his work in 8 shows and was also a member of the Circle Bar B Theater Company. He then transferred to the University of California, Irvine drama program where he was fortunate to garner praise from the Head of Directing, Dr. Keith Fowler, for his portrayal of Count Beaudricourt in The Lark- "Sean managed to show us a character who was proud and egotistical, but also persuasively intelligent and thoughtful and he had a brilliant and inspired take on The Lecturer from Reefer Madness." He also studied Shakespeare with Dr. Robert Cohen as well as voice/speech/dialect with Philip Thompson and dynamic movement with Anne Loui before earning his bachelor's degree in 2008.

Since then, Sean has performed in various productions around Los Angeles including David Mamet's Sexual Perversity in Chicago at the Lyric-Hyperion Theater in Silver Lake. He is also involved with his improv/sketch comedy group, The Associates of Awesome, performing in various venues around LA, as well as The Groundlings School of Improvisation.
