Parish Council

This council of men and women, six in total, meets monthly with our Rector to oversee the life and health of this community. They are a dedicated group that pray for this community and bring various skills, gifts, and experience to the leadership of the church. They do all kinds of things behind the scenes that make the ministry of Church of the Cross go smoothly. They also serve as the stewards of the church's resources.  

Neighborhood Group and Ministry Team Leaders

Our Neighborhood Group leaders and ministry team leaders provide significant leadership in the life and ministry of our community. They are supported and encouraged by our staff in their various ministry roles. These leaders gather for a retreat day each August to pray, deepen relationships, and talk about and shape our vision for the year ahead.
