Saint William is one of the most vibrant and active parishes in the area. With more than 6,700 families, our numbers are large but community is important. We always welcome new members to our parish, and we love to greet them in person. Whether it’s by one of our priests before or after Mass, one of our many volunteers who serve as ushers or in the Welcome Center, or by one of our staff members, the welcome is on behalf of our entire parish family.

To register, simply visit the parish office, which is conveniently open:

• Monday - Friday, 9 AM - 6 PM
• Sunday, 8:30 AM - 4:30 PM

Stopping in will not only help us get to know you, but will also ensure that all your information is properly entered into the parish database.

When registering, please have this family member information on hand:

• Phone numbers
• Email addresses
• Photo ID

Having needed information on file will ensure that:

• We have your family’s sacramental history in order
• You and your children have access to our religious education programs
• Scheduling for your family's important dates (baptisms, weddings, and more) will be easier
• You are receiving all accurate and up-to-date communication from the parish.
