Founded in 1927 to accommodate the need for a new Catholic Church in north San Bernardino, Holy Rosary enjoyed a rich faith tradition that mirrored the evolution of the diocese.
It became Our Lady of the Rosary, the Cathedral Parish of the Diocese, in November 1978 after its pastor, Phillip Straling, became the first bishop of the Diocese. In addition to serving more than 1,500 registered families in San Bernardino, Holy Rosary also hosts numerous diocesan events including the Chrism Mass, Diocesan Awards Ceremony, Migration Mass and confirmation ceremonies.
Holy Rosary also includes a parish school, Holy Rosary Academy, built in the 1950s.
Demographic changes in San Bernardino brought young families into the parish, which responded with new programs for them. Community organizing programs helped improve the neighborhoods and clustering with other Catholic parishes in the city brought about a greater unity and sharing of resources.
