Experience the Power of Women Giving as One

Through collective giving and responsible stewardship, we empower Sonoma Valley women to invest in a more sustainable nonprofit community. Our efforts change lives and enrich our own. Here’s how: 

  • Every member donor makes an annual, fully tax-deductible, minimum contribution of $1,200. 
  • $1,000 goes to fund grants, while $200 goes to help cover the operating expenses of our volunteer-led organization. 
  • Each January, valley nonprofit organizations apply for grants. 
  • Member volunteers review proposals, make site visits, and select finalists. 
  • All members vote on grant recipients, and grants are awarded in the spring. 
  • Engagement continues throughout the year via social events, educational programs, and volunteer opportunities. 

As a member donor of Impact100 Sonoma, you can: 

  • Meet dynamic, philanthropic women of all ages and backgrounds. 
  • Help fund a range of nonprofits with one contribution. You have a vote in where your grant donation goes. You’ve entrusted it to proven, responsible stewards. And it will make an immediate impact. 
  • Learn more about your community. Our grants background materials, educational programs, volunteer opportunities, and nonprofit partnerships give you a view on all Sonoma Valley has to offer—and where you can help. 
  • Share our commitment to equity in all we do. 
  • Participate in a way that suits your needs and interests. Be as involved as you want. Make an additional donation and direct it to the use you prefer, including to help sponsor members who might otherwise be unable to join.
