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.
Pittsburg Theatre Company
Pittsburg Theatre Company began as an Adult Education class lead by Betty Brown and was incorporated on April 9, 1979. In its 45 year history it has been producing 3-4 mainstage shows each season.
The company has continued to grow, improving the quality of its productions with each season. PTC has expanded its offerings to include the popular PTC@Steeltown Black Box series of plays. Many of these plays are taken “on the road” to the Campbell Theatre in Martinez. PTC also offers a summer youth theatre program.
In 2022, Pittsburg Community Theatre changed its name to Pittsburg Theatre Company to reflect the increasing quality and diversity of our performing arts programs. We remain a community based, volunteer led organization. PTC is also the resident theatre company of the California Theatre in Pittsburg.

OUR MISSION
Produce Quality, Independent Comedy shows within the Contra Costa Area while supporting local charities, and promote other local comedy shows, showcases, and open mics.
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.
