The Marin Group Executive Committee is the governing body for the Sierra Club at the local level. It oversees essential functions of the Marin Group: deciding local conservation policy, endorsing political candidates, and administering programs and activities. All Club members who live in Marin County are automatically members of the Marin Group and are eligible to serve on the Executive Committee. This committee meets the second Thursday of every month from 7:00 - 7:30 PM. 

The Conservation Committee vets environmental issues of concern leading to official letters, suggestions for policy and positions, and meeting with local elected officials and staff. This committee meets right before the Executive Committee on the second Thursday of every month, from 6:00 - 7:00 PM. All Sierra Club members are welcome to join this committee at any time to listen and vote on issues that are being discussed.
