Welcome to St. William the Abbot CYO online registration system.

Registration for 2015 Basketball for Girls and Boys was held from June 15 through June 22. There is a second registration for select grades from Saturday August 8 through Sunday August 16. If a player wishes to register for a grade where the registration quota has already been reached, they may sign up and be placed on a waiting list.

There are still openings for the 5th grade volleyball clinic that will be held from August 10th - 20th.  Please email if you are interested.

Please note that jewelry, including earrings, is not permitted at games or practices.

We are looking for new coaches and team parents.

Further information about volleyball can be found at the St William Volleyball website, . If you have questions or would like information about coaching, please email
