Catholic Community of Waukesha

Welcome to St. William Parish


Welcome to the St. William pages at the Catholic Community of Waukesha! We are delighted that you took the time to look at us. We have much to share with you and we invite you to browse these pages to discover who we are and the many things we are about and the many services we provide.

We are a community of believers in the Roman Catholic Tradition who live and preach the Word of God and celebrate the sacraments of the Church. We welcome all who come to us as did our patron, St. William of Vercelli. We were founded on Waukesha's then "Westside" in 1957 and we have grown to over 6,000 members. We would be pleased to welcome you into our community as well.

The St. William pages offer you much information and I invite you to spend some time with the information provided. If you have any questions, we would be happy to answer them. Simply email our webmaster at or phone the parish at 262-547-2763.

We hope the time you spend on these pages will encourage you to pay us a visit in person. Know that you are most welcome here at St. William Parish.

See you at Mass!
