Join Our Parish

Welcome to St. Sebastian!

We have an active and prayerful parish with many opportunities for you to worship with us and to share our life in Christ. As a family of believers dedicated to carrying out the mission of Jesus Christ, we welcome you.

Located in the diverse Washington Heights neighborhood near Wauwatosa, for more than 100 years we have lived out our call to discipleship by offering sacramental life, service, teaching and healing to all God’s people.
