100+ People Who Care: Marin County (100MARIN) is a members-only circle of like-minded, philanthropic individuals who are dedicated to enhancing the support and awareness of Marin County nonprofits. Founded in January 2015, the group has over 200 members. 

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

  1. To increase each circle member’s overall giving impact 

  2. To develop and strengthen the network of individuals who are passionate about the local non-profit community

We invite you to explore this site and become part of Marin County's premier giving circle: #100MARIN
