On Stage Vacaville

Setting the Stage for the Performing Arts in Vacaville Since 2001

On Stage Vacaville (OSV) is a Non-Profit 501(c)(3) organization dedicated to the promotion, support, development and growth of Arts Appreciation and Programming for the Vacaville community.

The On Stage Vacaville board is dedicated to maintaining legacy relationships, and creating opportunities for new and underrepresented audiences and performers to participate in the arts.

On Stage Vacaville is a volunteer run organization located in the rural city of Vacaville in California’s agricultural central valley. The theater was established as part of the city’s economic development effort to draw new businesses. For years theater audiences were mostly from the upper socioeconomic class. In 2011, On Stage Vacaville began a focused effort to sponsor and/or co-produce programs that would appeal to the broader community and underrepresented individuals. Our programs have drawn disabled adults and youth, low income youth with an interest in music, school children, and non-typical theater-goers who have an interest in an educational topic that is offered through performance.


On Stage Vacaville is a 501c3 non-profit that strives to promote genuine human expression through the arts and create experiences for our community to be valued, represented, and entertained.

Our Values

⦁ Respect: You are welcome into the organization as your authentic self.
⦁ Collaboration: You are free to ask questions and make mistakes while you learn.
⦁ Courage: You are encouraged to share your ideas without fear of retribution.
⦁ Innovation: You are safe to question the status quo, raise concerns, and provide dissenting opinions without fear of negative consequences.

Our Promise

We are a team, and we acknowledge the importance of empowering our board members to make decisions and collaborate as we all carry this important mission to be effective in our communities through art. We stand together and support each other through our jobs and promise to uphold and represent the integrity and values of OSV with our community, audiences, volunteers, partners, the City of Vacaville, and the general public.
