About Us

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 all.  We invite you to join us for Mass, participate in activities interest you, and become an active part of our parish life!
