About Us



Mysterium Theater

Mysterium Theater was founded by Marla and Robert Ladd in 2009.  Since then, the troupe has staged a full spectrum of plays.  In 2014, the City selected Mysterium to lease La Habra's Depot Playhouse, which had been closed for several years.  After a complete renovation of the Depot, Mysterium staged several plays beginning in September of 2014, and has continued to offer a variety of musicals, plays, magic shows, stand-up comedy and more!  The theater’s motto is, “come play with us” and the organization hosts a variety of intimate shows for kids and adults such as: Aladdin, The Little Mermaid, Godspell, Dancing at Lughnasa, Freckleface Strawberry, Mysterium Monthly Variety and Cabaret Shows along with Magic, music and more...


We generate excitement

 We are a theater that embraces and celebrates the life of theater with great shows and talented crews and casts. 

Our team of folks have become not just friends...but family.  We are grateful to get to play with people with whom we really enjoy creating such fun work.
