The Servites responded to an invitation by the Roman Catholic Archdiocese of Los Angeles to open the school in 1957, teaching the first classes at nearby St. Philip Benizi Elementary School until the first building was completed. The main building was officially dedicated on February 12, 1959. Major expansions since then include a gym and aquatics facilities, theater, new classrooms, and new science and library facility. Servite's wrestling room was also a recent addition to the school on the campus' priory lawn. A new parking lot, dedicated to former dean Tim O'Hara was added for more faculty parking.
Admissions
Admission to Servite is based on academic transcripts, entrance examination, activities, arts and athletics. The admissions process includes a review of academic transcripts; entrance examination; interview of parents and the student; letters of recommendation from teachers; participation in activities, community service, arts and/or athletics; and letters of recommendation from alumni or parents. Servite has an Early Admission Process that enables young men to apply as early as October of their 8th grade year. Upon completion of the admission process and receipt of the first set of grades for their 8th grade year, students may be admitted to Servite as early as November of their 8th grade year.
In 2007 Servite implemented a student leadership program by dividing the student body into 8 student-led communities called "Priories" and 48 smaller student-led homeroom communities. Each week a block period is dedicated to student-led leadership activities. The Priories are based on the Seven Holy Founders, and St. Philip Benizi. The school is known for its academic curriculum, sports tradition, performing and visual fine arts programs. The motto Credo ut Intelligam illustrates the emphasis the school places on developing leaders who are faith-filled men of God. The academic curriculum has a wide variety of courses, including College Prep, Honors Placement, and Advanced Placement courses. All courses offered at Servite High School are designed for the college- and university-bound student.

All required courses in all disciplines must be passed and no student may graduate from Servite with an unredeemed 'F' on his transcript. In addition to credit requirements, no ‘F’ policy, and Christian service hours, there are also specific course requirements.
