Sierra Fisk
Managing Director
Assistant Director, Producer, Acting Coach

As an actress, producer, director, model and stunt performer, Sierra has worked most of her life in film, television, commercials, print, and her first love: theatre! Sierra received her Theatre B.A. with Honors from UC San Diego. She continued her education and training in England, at the University of Kent in Canterbury. Upon moving to Los Angeles, she became the Managing Director of The Gangbusters Theatre Company, and produced and acted in numerous Ovation, NAACP and LA Weekly Award winning productions. (IMDB)

Sierra has always cherished her work with children - whether nannying, tutoring, or moonlighting as a Mad Scientist at children's birthday parties.  In a natural turn of events, Sierra began working in L.A. as a Drama Director in eight different public schools.  She has directed children all over the San Fernando Valley in musical productions, improv shows, Shakespeare, and classic straight plays.  In 2008, Sierra met Chera at Lanai Elementary School and was the musical director for ACT-1's first production, SEUSSICAL: THE MUSICAL.  Shortly thereafter, she and Chera decided to join forces to produce Academy for Children's Theatre, the highest-quality children's theatre company in the Valley.  


Outside of ACT-1, Sierra loves to privately coach children and would like to publish some of her own plays.  She also very much enjoys working as a Mentor at The Unusual Suspects, teaching at-risk teenagers how to write and perform their own material.
