Archbishop John J. Cantwell asked the Religious of the Sacred Heart of Mary (RSHM) to establish the Valley's first high school.

Reverend Mother M. Baptiste Holohan and Reverend Mother Gertrude Cain began the search for suitable property and found a home owned by Mr. Henry Rotham on Laurel Canyon Boulevard, a half block south of Ventura.

The school was named Corvallis, a combination of two Latin words: cor(da): heart and vallis: valley.

In 1981, for various internal reasons, the RSHM, which owned the property, transferred operations of the school to the lay administration and parents, under the new name, Our Lady of Corvallis.

The newly renamed school continued for six more years, eventually closing its doors in June 1987.
