Our History

On November 19, 2023, OneOC celebrated it’s 65th Sapphire Anniversary!

Established in 1958 as the Newport Bureau of Volunteerism, we originated as the inaugural community service initiative of the Junior League of Orange County, ultimately evolving into the Volunteer Center of Orange County.

In a transformative move in 2010, we rebranded as OneOC, reflecting our dedication to expanding nonprofit services across the entire county and again in 2015 with the launch of the Center for Business and Community Partnerships. These key years inspired and empowered connections between the business and the nonprofit sectors, through employee volunteer engagements and charitable giving programs, amplifying a greater social impact for all.

Fast forward to 2017 when we strategically developed our 2020 Roadmap. This marked a significant shift, concentrating our efforts on providing Management Services Offerings (MSO) to nonprofits and companies. Our objective was to enhance their abilities to make a profound impact within their communities.

As we joyously celebrate our 65th anniversary this year, our enduring commitment to Building a Lasting Legacy stands as a testament to our unwavering dedication to creating positive and lasting change in the community. Join us in commemorating this milestone and continuing our journey towards a brighter future.


Our client-care approach centers on fostering engagement, promoting innovation, and streamlining complexities. By doing so, we aim to empower organizations with the essential infrastructure required to execute their missions with greater ease and effectiveness. We are dedicated to being the catalyst that accelerates the impact of nonprofits, ensuring they thrive in their endeavors to make a positive and lasting difference on the communities we serve.
