Impact100 Sonoma’s grants work is an essential component of contributing to a thriving Sonoma Valley.  Serving as a Grant Review Committee (GRC) member draws you into engagement with our nonprofit community.  You will review the nonprofit applications, explore them in depth through site visits, and determine which you believe can have the most significant impact and also have the greatest opportunity to successfully utilize the funds.  

If this sounds like meaningful work, and you want to become involved, read on for more detail about Grant Review Committee participation and what to expect. 

Registration for 2023 is closed. Please check back in the fall for a 2024 Committee.

What do Impact100 Sonoma Grant Review Committees do?

Grant Review Committees are established annually for the winter/spring grant review season. Committee members read and review grant applications and participate in a thorough vetting process that leads to recommending finalists to be voted on by the entire membership.

What will the 2023 Impact100 grant review process look like?

Is there a calendar for the grant review committees? How much time does it take?

Our grant review season will take place on a timeline from January – April 2023. We anticipate that meetings will be held in-person, though some site visits may be held via Zoom. Committee members will be expected to devote approximately 20-25 hours of their time to the process. Key dates for 2023 are in the Grant Review Committee Calendar on the right-hand side of this page.

Serve on the Financial Review Committee

What does Impact100 Sonoma’s Financial Review Committee do?

The Financial Review Committee (FRC) is tasked with reviewing the financial documents submitted by the various non-for-profit organizations applying for grants each year. Review generally takes place in the second half of January, in a short, concentrated period. If you have experience in evaluating and analyzing financial statements and budgets, you may want to serve on the Financial Review Committee.

Click here to send an email to our administrative assistant with your name and contact information and noting your interest in the FRC. Once you have been approved to serve on the FRC, please register at the same online link (above) as GRC members.
