About

Founded in 2009, Impact100 Sonoma is a women’s philanthropic organization that pools member funds to support nonprofits serving valley residents from Schellville to Kenwood. Our vision is to support a just and thriving Sonoma Valley by empowering women to invest in a more sustainable nonprofit community through collective giving, responsible stewardship, and active engagement while emphasizing equity in our approach to grantmaking. Today we have more than 300 members and typically grant more than $300,000 annually. Our cumulative grant total of $4.4 million and climbing makes us one of the valley’s largest, most reliable funders.

We welcome new member donors throughout the year and award grants each spring. Our Community Service Hub, which is open to the public, matches caring locals with grant recipients past and present seeking volunteers, pro-bono services, materials, and other assistance
