Rosary was founded in September 1965 under the auspices of the Archdiocese of Los Angeles and administered by the Sisters of St. Joseph of Orange to provide greater opportunity for girls residing in the central and northeastern portions of Orange County to attend a Catholic secondary school. In 1976 with the establishment of the Diocese of Orange, Rosary came under the jurisdiction of the Roman Catholic Bishop of Orange. Presently Rosary is also under the supervision of the Vicar of Faith Formation/Superintendent of Catholic Schools. Students now represent a broader geographic range that includes the counties of Orange, Los Angeles, Riverside, and San Bernardino.  

Rosary is accredited by the Western Catholic Educational Association (WCEA) and is co-accredited by the Western Association of Schools and Colleges (WASC).

The Rosary Crest

Rosary’s crest presents the school’s philosophy in visual form.

The sun symbolizes growth — spiritual, intellectual, emotional, and physical. The open hand characterizes a student’s readiness to receive knowledge and to give to others.

The cross is the traditional symbol of Christ and the letter “M” is symbolic of Mary which is superimposed on the cross to signify that the pattern of our life is a journey toward Christ through Mary, the patroness of Rosary.
