Church Leadership

The leadership of Advent Lutheran Church consists of lay men and women who give of their time, talent, and treasure to assist with the spiritual needs of the congregation.  Through their oversight of educational programs, fellowship, mission work, and other works of compassion – done in thanksgiving to Christ who has saved us by grace through faith – we pray we share that same message of forgiveness with our neighbors and to the far reaches of the world.
