The Sisters of Charity opened St. Joseph by-the-Sea in September, 1963, to meet the needs of a rapidly growing South Shore community. Each succeeding year saw the school grow in students and faculty. Since the first graduates in 1967, more than 8,000 students have earned their Sea diplomas.
In 1973, the school entered a new phase in its history when a diocesan priest was appointed principal and the school began admitting young men.
In 1982, four new classrooms were added and, in 1983 an 11-acre sports complex was completed. In 1992, an Olympic-size track was built to accommodate a co-ed student body of 1,400 students.
