The Holy Spirit Catholic Church of Fountain Valley is a generous and dedicated community of faith. We celebrate the sacraments with enthusiasm and commitment. We share willingly our gifts of time, talent, and financial resources to enable many ministries that make the Body of Christ a visible and effective presence in our world.

We strive to live our Catholic faith enlivened & guided by the Holy Spirit & bring the fruits of the Holy Spirit to others.

Established in June of 1972 by Cardinal Timothy Manning, who was then the Archbishop of Los Angeles, our parish was given the beautiful name of "Holy Spirit". Our Sunday Masses were celebrated at Fountain Valley High School cafeteria for almost two years until the completion of the first part of our multi-purpose building in 1974, consisting of six classrooms and two offices. The large hall was added in 1976, and became the center of our Eucharistic celebrations until our church building was dedicated on December 6, 1987.

Today, our parish community has grown from a few hundred members to more than 3300 families, and we continue to grow. We are a multicultural parish incorporating people of many heritages typical of this area of Orange County. We are committed to building up the Body of Christ as part of the Church of the Dioceses of Orange, and as part of the larger Roman Catholic Church.

Holy Spirit Church is blessed with three priests and three deacons serving our community. Our Pastor is Fr. Marito Rebamontan (also known as "Fr. Mario"). Our associate pastors are Fr. Sean Condon and Fr. Joseph Long Kim Nguyen, and our deacons are Deacon Bill Cobbett, Deacon Jerry Dao and Deacon Phil Goodman.
