About Us

On October 22, 1946, a delegation from Our Lady of Guadalupe appeared before the Chino Planning Commission with an application for zoning and construction of a new church, which would be named Saint Margaret Mary in memory of Margaret Gallican. This church was to be the sister church of Our Lady of Guadalupe which had exceeded its capacity. Its conception was announced by Most Rev. Charles F. Buckley, Bishop of San Diego in early 1946. The first Mass was held on October 17, 1947 by Rev. Fr. Philip Watz.  Let us thank our Lord for the dedication, determination, and dynamism of the past generation through whom the foundation of our church was made possible. After 75 years since the groundbreaking for our parish took place, we stand firmly and grow steadfastly.
