History & Philosophy


Holy Trinity School celebrated its 60th year of educating children in the South Bay of Los Angeles in the 2010.

How it all began

Under the leadership of Monsignor Gallagher, the parish purchased land for the school in 1950; and the groundbreaking ceremony took place on March 5, 1950.  That same year, the Sisters of the Presentation of the Blessed Virgin Mary moved into the newly converted convent on Hanford Street.  This community of sisters served Holy Trinity School from its inception in 1950 to 1990.  In September of 1990, a lay principal was appointed.

The school opened on October 4, 1950, while the building was still under construction.  Sister Mary Thaddea, the principal, greeted Holy Trinity’s first students.  There were 334 children in grades one through seven, meeting in three completed classrooms and the auditorium.  The faculty consisted of five religious and two lay teachers.

On September 17, 1951, the second year began with the building completed and an enrollment of 434.  On November 4, 1951, the school was dedicated by Bishop Manning.  The grades now ranged from first through eighth.  Graduation of the first class took place on June 12, 1952.  Since this first commencement over 3,800 students have graduated from Holy Trinity, including many of our present students’ parents.

Over the years, Holy Trinity has grown to be an active and thriving school.  In 1956 and 1957, two annexes were constructed, adding five classrooms.  Kindergarten was added and opened on October 2, 1956.  The 1958-1959 school year opened with an outstanding enrollment of 940 children.  All classes were double classrooms with fifty or more students.  Holy Trinity remains a double classroom school.  The school facilities include eighteen classrooms, a library, a Mac Computer Lab, a Scholastic/pc computer lab, multipurpose room, a science lab for conducting experiments, and a math lab.

In the summer of 2001, the existing school building was renovated. In 2006, we launched our preschool.

Today

We have over 60 teachers and staff; and over 500 students in our 19 co-educational classes, preschool through eighth grade.  Our curriculum, organization, student services, and facilities are evaluated in light of our philosophy by Western Catholic Education Association and Western Association of Schools and Colleges from whom we receive our accreditation. We have received a full six year accreditation through June 2018. We are proud of past accomplishments, and our faculty, staff, and parents continue to explore ways for insuring future growth and academic excellence.

Philosophy In Motion

Holy Trinity provides an educational experience which prepares our students academically, morally, spiritually, and socially for high school and a full Christian life. Our school fosters the worth of the individual and promotes a strong sense of personal and social responsibility.

Holy Trinity stresses intellectual and spiritual discipline, as well as physical well being. We also value compassion. responsibility, generosity, and idealism. Our school extends to students a means of personal growth by providing a rigorous academic, physical, and spiritual program in an atmosphere of courtesy and concern for the individual.
