Our History

It is rare that an advisory partner offers focused nonprofit expertise along with the data-driven insights, expertise and solutions of a national consultancy. As a division of SullivanCotter, C3 delivers exactly that.

Leveraging decades of experience working with healthcare and nonprofits alike as SullivanCotter, C3 now stands on its own to serve private and community foundations, policy and advocacy organizations, research institutes, colleges and universities, charitable and service organizations, arts and cultural organizations, and associations among others.


C3 exists to partner with the world’s most impactful organizations to navigate people and culture solutions.


A society in which nonprofit employment is synonymous with meaningful work, thriving culture and competitive, fair and sustainable pay.
