The ACW is a fellowship organization for the women of St. Mary's, age 16 and older. The group gathers on the first and third Mondays of the month (excluding summer months) at 1pm, in the parish hall. The ACW raises money for charitable causes in the Windsor community, hosts social events, and contributes to the monthly coffee hour rotation after the 10am service. Inquiries about the ACW can be directed, through the office, to President Andrea Zold.
