Who are the Members of Impact100 Sonoma?
Impact100 Sonoma is open to all women 18 or older who live in, or who wish to support, the Sonoma Valley community. Each $1,000 donation provides membership for one year’s grant cycle.

Is my donation to Impact100 Sonoma tax-deductible?
Yes. Contributions made by December 31 are tax-deductible for the year in which the donation was made. Impact100 Sonoma is a Section 501.c.3 nonprofit organization.

What is Member Plus?
Members who are able to contribute above and beyond the basic $1,000 donation help defray our organization’s operational costs such as events, communications, website and administration. Every contribution is greatly appreciated, no matter what size.

What is required of a Member?
Once you join, your level of involvement is entirely up to you. You can simply join and cast your vote for the annual grant recipients, or you can become actively involved on a Grant Review Committee, Standing Committee, or serve on the board. Ours is a no-guilt organization! Every membership dollar is equal in serving our community.

Once I join, how long is my membership in Impact100 Sonoma?
Each annual donation provides membership for the next calendar year. Women who donate by December 31 of any year are eligible to vote on grant recipients in May/June of the following year and qualify as members for the entire year.

How does Impact100 Sonoma stay in touch with its members?
Impact100 Sonoma uses email communication and social media to stay in touch with our members. In addition, we publish a quarterly newsletter, monthly calendar of events, and host many events during the year.

I would like to contribute more than $1,000. Do I get more than one vote?
No. Our founding principle is "one woman, one vote." Member Plus donations are an essential part of helping to offset operating costs, as well as events and activities for members.

My company matches funds for charitable donations. Can I give $500 and have my company match it to make my total $1,000 donation?
Yes. Businesses or employers can contribute in any amount to an employee's membership in Impact100 Sonoma. We also appreciate matching funds from employers and use these funds to offset operating costs.

Do you allow my Membership to be charged on a credit card?
Yes. Click here to learn more about paying with a credit or debit card online.

How is it possible that 100% of my membership donation goes to fund grants? How are administrative and membership recruitment expenses covered?
Impact100 Sonoma seeks gifts and sponsorships from individuals, local businesses, family and private foundations, and in-kind donations specifically for administrative expenses. We encourage every member to become a Member Plus to help defray these costs.

How can I join Impact100 Sonoma if I can't make the $1,000 contribution?
Learn about our Employee Sponsorship and Individual Sponsorship Programs. If you are between 21 and 39, apply for a NextGen Program sponsorship.

How can I support Impact100 Sonoma if I don't become a member?  

You can become a Friend of Impact100 Sonoma and play a very important role in our organization. All Friend donations are tax deductible. While your Friend donation does not provide you with voting rights, it will help ensure that 100% of each member's $1,000 donation goes entirely to fund grants.

Can men participate in Impact100 Sonoma?
Men are encouraged to become Friends of Impact100 Sonoma (see above) and may volunteer to help at activities and events. They may not become members.
