Board of Governors

The Board of Governors of Commonwealth Club World Affairs of California reflects the strong commitment among Bay Area leaders to the Club's public affairs role. Members of the board are affiliated with a wide variety of business and civic organizations.

Board members oversee the Club's activities through a number of committees, working closely with the presidents and CEOs and the Club's staff.

The board chair serves for two years. Martha C. Ryan and Jonathan Visbal are the current co-chairs of the Board of Governors. The board is comprised of about 70 members. Past presidents and past chairs of the Club's board also sit on the board as voting members for three years following their leadership tenure, then for life as nonvoting members of the board.
