Join & Participate

Impact100 Sonoma members volunteer at FISHImpact100 Sonoma is made up of 100+ women, who each contribute $1000 annually for a shared purpose: to make a difference in Sonoma Valley. The number and amount of grants are determined each year by the number of women who join Impact100 as members. The more members we have, the more grants we can give. Every dollar contributed goes directly to support local nonprofits.

Here you will find Membership Forms for new and renewing members, information on the benefits of membership, and responses to frequently asked questions about membership in Impact100 Sonoma.

Once you become a Member of Impact100 Sonoma, you can be involved as little or as much as you like. You may choose to do nothing more than donate $1,000 and then cast your vote at the annual meeting in June. Or you may choose a higher level of involvement by participating on one of the Impact100 Sonoma committees or by offering additional support.
