Our Denomination



Westminster Presbyterian Church of Tiburon, California is affiliated with the Presbyterian Church (U.S.A.) denomination. PC(USA) is governed by councils, which exist to help congregations and the church as a whole be more faithful participants in the mission of Christ. The councils of the church are the Session, the Presbytery, the Synod and the highest governing body, the General Assembly. The Session is the leadership council for our congregation and is composed of ruling elders, elected by the congregation to active service, as well as all installed pastors (also called teaching elders). The Session's main responsibilities, together with teaching elders, are to exercise leadership, government, spiritual discernment and discipline and have responsibilities for the life the congregation as well as to the whole church.

Our History

In the Beginning...

In 1957, ninety-five faithful dreamers planted the seed and leaned into God’s calling to be a Presbyterian presence in southern Marin County (California). Sunday servicesstain glass window were held in burlap-lined quarters over Herbert’s Sherbet Shop on the Tiburon Boardwalk. Children attended Sunday School in two Northwest Pacific railroad cars. In 1960, the congregation celebrated the transition to the current location with a small sanctuary, classrooms and offices. In 1991, a beautiful new sanctuary was dedicated. Since our beginning, six pastors, two dozen interns, five parish associates and hundreds of elders and deacons have guided the congregation.
