Together We Give, Learn
and Make a Difference

Join Us

Women join Impact100 because together, our voices are stronger, our financial contribution is greater, and collectively, our impact is deeper.  Our work changes lives.

We join to gain a better understanding of the needs in our communities, to learn about the work of local nonprofits, to become more confident as donors, and to look for opportunities to roll up our sleeves and get involved. We join because we value being part of a community of diverse women where we can learn and contribute ideas and leverage our individual donations.

To become a member,  a woman must be 21 years or older, and fund her membership contribution of $1,150 before December 1. Of the contribution, $1,000 is directed to the annual grants pool to be awarded each June, and $150 supports the cost of operating Impact100. (Please note: we request a membership contribution of $1185 if you choose to pay through Paypal with a credit card.  This platform comes at a cost to us and we hope to keep these costs low to focus on our members and grantmaking.  Thank you!) We also offer an installment option, please email for this option.
