The first step is to come to the front office to pick up an information packet. At that time, you can also pre-register for a pre-baptismal class. There are both English and Spanish Baptism Preparation classes.
Baptism Preparation classes are held on the 3rd Saturday of every month. Spanish classes begin at 8:30 AM, and English classes begin at 10:00 AM.
Both parents and godparents/sponsors are required to attend and participate in an entire class offered at Saint William or another Catholic Church. If parents and godparents/sponsors attend a class at another church, they will need to provide written proof of attendance of the Baptism Preparation class at another Catholic parish within the past two years.
For more information, see our Baptism page.
