Prayer and Worship

If you are interested in learning more about one or more of our ministries, please contact:

Tommy Sustaita, Volunteer Coordinator at 512-600-8190 or volunteer@st-william.org to schedule a meeting.

Parishioners have many options for volunteering in our prayer and worship ministries.  The parish itself depends upon those who pray and offer sacrifices for it, and on those who enrich it through various celebrations of the liturgy and feast days throughout the year.


Music Ministry

Saint William is fortunate in having beautiful music at our liturgies.  Many devoted volunteers offer their time and talents within the music ministry.

We are regularly recruiting more singers and instrumentalists for all our choirs. We count on the efforts of people just like you. You can contribute to the beautiful music that touches so many during the Mass. If you are interested in joining us, please email music@st-william.org for more information. 

We are very privileged to have six choirs, which provide music for all six weekend Masses held at Saint William. We also have a Children's Choir that is on a rotating schedule.
