Onstage Repertory Theater

Onstage Repertory Theatre was founded in 1978 by Helen Means.

Its first venue was the back room of Dan's Bar in Walnut Creek.

In 1982, the company took up residency in the old Pleasant Hill School House

and continued to perform there, until the building was condemned in 2008.

As a vagabond company, Onstage has performed at a variety of theaters,

including the Lesher Center for the Arts (Walnut Creek)

and  Cue Productions (Concord).

In the Fall of 2013, Onstage Theatre took up residency

in the Martinez Campbell Theater at 636 Ward Street.

Spontaneous Mind

     Spontaneous Mind, an educational non-profit, uses applied improvisational tools to improve communication, collaboration, and innovation.


     When people engage in improv exercises, they learn to listen actively to others, to respond thoughtfully, and to work collaboratively.  These skills are critical in any setting where communication is essential, such as in the workplace or in personal relationships.


     Founders of Spontaneous Mind, Jaime Rich and Randy Wight, co-produce Act II improv and Partners in Crime, while continuing to perform in both shows.


     Jaime Rich is lead instructor for improv classes at the Campbell as well as teaching all over the East Bay for organizations like Town Hall Theater, Acalanes Adult Education, Mt. Diablo Adult Education, and Martinez Adult Education, just to name a few.


     Randy Wight is head of instruction for Standup Comedy Classes at the Campbell.  Teaching at Under the Sun Studios beginning in 2011, Randy uses a mash up style of improvisation, standup and classic public speaking platforms to give his students a solid foundation to take on open mic nights or even headlining gigs.

Plotline Theater Company

     Plotline Theater Company was started in 2018 by Randy Anger after a mere 44 years ruminating about the possibility of starting a theater company.  Randy started the company with Matt Davis with the goal of creating moving, memorable, and sometimes hilarious memories for audiences from greater Contra Costa County.

     Randy is an actor, vocalist, musician, composer, producer, and director who has been performing since the age of 5 as one of 5 generations of performing artists.

     Matt Davis is an actor, singer, musician, magician, producer, and director who has been performing for over 20 years.  They are committed to serving this community by providing the best theater possible in the intimate, inviting Campbell Theater in Martinez California.

Contra Costa Comedy

     Contra Costa Comedy is a live event producer that promotes live comedy, while benefiting charitable organizations.  It is founded by comedian Bob Johnston.  Bob’s vision is to let laughter and giving flow where it is needed.

     You can follow Co Co Comedy for local events and daily laughs on Facebook at CoCoComedy.

     Bob Johnston has been performing stand-up comedy around California and the Pacific Northwest for the last 23 years.  He and his wife Vidah moved to Martinez in 2009.  When he learned that Martinez had an outdoor amphitheater, the idea for Comedy Under the Stars was hatched as a way to allow the community to use the amphitheater while raising money for local charities.
