The Vestry is the governing body of St. Margaret's, working with the rector to offer leadership in ministry and care for the resources and property of the Church.  With a total of nine members, three new members are elected each year at the Annual Parish Meeting to serve a three-year term.  Vestry officers include the Senior Warden (appointed by the rector), the Jr. Warden (having primary responsibility for care and maintenance of the buildings and grounds), the clerk, and the treasurer.

Vestry meetings generally take place on the 1st Thursday of each month at 6:00 p.m.  Vestry meetings are open to anyone who wishes to attend.
