The Vestry is headed by the Rector and the lay management team, including the Senior Warden, Junior Warden, Treasurer and Clerk. The Vestry is currently composed of 9 members, each serving for 3 years. Members of the Vestry also provide active guidance and support of the overall life of the parish.  The Vestry meets regularly on the second Sunday of each month after the service.  Parishioners are encouraged to discuss concerns, questions and ideas with any member of the Vestry.

A Nominating Committee consisting of the Rector and the retiring members of the Vestry puts forth a slate of names for Vestry positions in advance of the parish’s Annual Meeting which is held in August of each year.  The members of the Vestry are elected at that meeting. Vestry members must be communicants of St. Andrew's by-the-Sea and at least 18 years of age.

Although the Treasurer and Clerk always attend Vestry meetings and are active participants, they do not have a vote in Vestry deliberations.
