We Invite You to Come & Experience the Sacred

St. Mary and Sons of Zebedee form a parish family whose members are committed to deepening their faith and living the Gospel. We are dedicated to serving the communities in Oakfield, Byron, and Lomira. Our churches reflect the small-town feel of the area. We strive to be a place to learn and grow in Catholic faith while continuing the mission and ministry of Jesus.
