St. Pius Church is a Catholic community committed to sharing our faith, rooted in the life and love of Jesus and the Gospel. We welcome, unite, and inspire all to enrich their faith through the sacraments and compassionate service to others.

"This is your parish, Fr. Fitzsimon," said the Archbishop.

Fr. Fitzsimon looked at the eight acres of hayfields bordered by eucalyptus trees. He looked at the rustic ranch house and barn, the abandoned water tower, and the tiny cottage with its small garden and lawn. This was the parish Archbishop Mitty had given to him.

On June 3, 1951, Fr. Fitzsimon celebrated the first Mass at St. Pius Church. The porch of the ranch house was covered in rows of movable chairs, and a portable altar had been donated by a neighboring parish, Our Lady of Mt. Carmel. People poured in from every direction. This, however, was only the beginning.

The Baby Boom of the '50s arrived, making a school a priority of the parish, along with a temporary church to replace the ranch house. Energy and enthusiasm ran high among the first parishioners, and fundraising of all kinds took place – boxed lunches, dinners, dances, rummage sales, fashion shows – all successful in raising money, but, more importantly, in building a parish community.
