We are a Catholic community of believers, 5,000 families strong, located in the beautiful college town of Claremont, California, in the heart of the San Gabriel Valley. We are a vibrant and diverse faith community, dedicated to Eucharistic worship and a sacramental life, sharing the Gospel, supporting each other and our community through more than 70 ministries and outreach programs, and promoting social justice. We are home to one of the leading K-8 schools in the Los Angeles Archdiocese, as well as thriving Vietnamese and Spanish-speaking faith communities of more than 700 families each. We invite you to visit us, worship with us, and join us as we strive to live out our commitment to the Gospel of Jesus Christ. Questions?
