School History

During the pastorate of Monsignor Henry Watterson in 1916, Holy Trinity Parochial Elementary School was established. The school opened with a class of twelve pupils in the first grade and a total of one hundred thirty pupils in six grades. The Sisters of Charity of Convent Station, New Jersey, staffed the school.

It was in 1916, that the elementary school building was erected on the corner of First Street and Trinity Place. Until the building was ready, four classes were held on the main floor of the church and two in the choir loft. In 1926, the elementary school building was extended along Trinity Place. The elementary school moved to its present site in 1976. For almost a century, Holy Trinity has prepared several thousand young men and women for responsible roles in family, civic, business, professional, and religious life in response to the call and demands of the total teaching mission of the Church.

In 1991 the parishes of Saint Helen, Our Lady of Lourdes, and Holy Trinity configured under cosponsorship. The school site remained at Holy Trinity while the governance was shared by the three pastors. The Mountainside Campus of Holy Trinity Interparochial School opened in September 2002 in an existing building at Our Lady of Lourdes. This early childhood center offers a variety of pre-kindergarten programs and a full day kindergarten.
