About 100marin

100MARIN is Marin County’s premier members-only giving circle, founded in 2015 with a vision to make a lasting impact on our community. In 2021, 100MARIN joined forces with the Center for Volunteer & Nonprofit Leadership (CVNL). Since 1964, CVNL has advanced nonprofits and volunteerism by strengthening leadership, encouraging innovation and empowering individuals in our community. Through collective giving, we empower individuals to come together and create a greater impact than they could on their own. 


Together, we aim to educate, engage, and connect individuals to the transformative power of philanthropy and social change. With your participation, we can extend our reach, support nonprofits, and build a stronger community. Join us in this meaningful journey of collective giving and experience the joy of making a difference. Contact us today to learn more about how you can become a part of 100MARIN.


How Our Giving Circle Works


Our giving circle operates on an annual basis. Members contribute each year, which is then pooled together to create a grant fund for Marin County nonprofits. Members then have the opportunity to nominate and evaluate potential nonprofit recipients, and collectively decide how to allocate the funds at our annual Fall Celebration.

Meet Us

100MARIN was created by a group of local, community-minded business professionals, with the following complementary objectives:


  • To increase each circle member’s overall giving impact
  • To develop and strengthen the network of individuals who are passionate about the local non-profit community.
