OneOC’s mission is “accelerating nonprofit success.” OneOC provides volunteer, training, consulting and fiscal sponsorship services for nonprofits to help them become as efficient and effective as they are passionate about their missions. In 2015, OneOC launched the Center for Business & Community Partnerships, which helps companies build and grow their giving and employee volunteer programs in order to maximize their charitable activities in the community, in turn generating more resources for local nonprofits.
