Preparing for the Sacraments

Riordan has a specific program for students (and other family members) interested in becoming Catholic or have missed opportunities for First Communion, Reconciliation and Confirmation. 

During the 2018-2019 school year, 10 Riordan students participated in this program, which culminated in baptism, communion, or confirmation at the Easter Vigil at St. Gabriel Church in San Francisco. 

For inquiries about this program for the coming school year, please contact:
