A parish in the Archdiocese of Los Angeles, St. Louise de Marillac is a community of people founded on the traditions and teachings of the Roman Catholic faith. We are committed to living in the fullness of our faith and embracing those seeking a relationship with Jesus Christ.
We number about 4,600 households, drawn from Charter Oak, Covina, Glendora, San Dimas, and the surrounding area. We are a blend of different cultures and languages – a diversity that strengthens our unity and gives substance to the warm welcome we extend to all.
In addition to the celebration of Sunday and weekday Masses, we offer a great variety of ministries and activities. There are religious programs, service opportunities, and social groups for men, women, and children of every age. We invite you to join us for Mass, participate in whatever activities interest you, quickly find friends, and become an active part our parish life. Welcome to St. Louise!
