Executive Committee

The Main Governing Board of Sierra Club California

The day-to-day governance of Sierra Club California is provided by an 11-member governing board of active Sierra Club members. The board, called the executive committee or ExCom, is responsible for managing staff, ensuring that the organization is financially sound, including by raising funds for the organization, and carrying out certain policymaking duties. The policymaking duties include appointing standing committees, including the California Legislative Committee, and taking positions on ballot propositions.

Ten of the ExCom members are elected for two-year terms at an annual convention held each fall.  ExCom members are limited to three consecutive two-year terms, after which they must take a two-year break before seeking office again. The California Conservation Committee (CCC) appoints a liaison to the ExCom.  The ExCom is led by a chairperson who is elected annually by the convention delegates.  You can see names and contact info for the current ExCom members below.

The ExCom meets monthly by teleconference, except during the annual convention in October, when it meets in person. It also has several administrative committees, including fundraising and political committees, which meet periodically.  ExCom meetings are open to all Sierra Club members. Occasionally, portions of a meeting may be closed for executive session to discuss personnel or legal issues.

For more information about how the ExCom operates and governs, see Sierra Club California's bylaws and standing rules.
