ABOUT US

Founded in 2009 by Annette Lomont and Christine Dohrmann, Impact100 Sonoma is a women’s philanthropic organization that pools member donations to support nonprofits serving valley residents from Schellville to Kenwood. Our vision is to foster 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.

The first Impact100 chapter in California, Impact100 Sonoma is an affiliate of Impact100 Global and a member of the national Philanos network. Today we have more than 300 member donors and typically grant more than $300,000 annually. Our cumulative grant total since 2010 of $4.4 million and climbing makes us one of the valley’s largest, most reliable funders. Impact100 Sonoma is a volunteer-led 501(c)(3) nonprofit organization, and all donations are fully tax-deductible.
