Volunteer Services

Connecting nonprofits with volunteers is what we’ve done for 53 years. It’s what we do, what we are, how we live. We connect young and old, diverse cultures and religions, and people of all economic levels to build a stronger, more vibrant Orange County. Learn More

Training Services

We train hundreds of organizations, their staffs and volunteers in our seminars, webinars and training sessions every year. Orange County’s nonprofits count on OneOC to increase their knowledge and improve their skills with quality, affordable educational experiences.

Consulting Services

OneOC helps nonprofits develop their capabilities, enhance their know-how and conserve their resources to wring more results out of every dollar. The OneOC team can consult with you on everything from governance and leadership to mission, vision and strategic planning. From program delivery and measuring impact to strategic relationships and resource development. And from internal operations to management evaluation.

Business Services

We can provide all the financial, human resources and other core functions nonprofits desperately need, but often lack. But don’t make the mistake of thinking we just provide these services only to small start-ups. Our full suite of business services are also in demand among mid-size and larger community projects, too.
