Newton Country Day School was founded in 1880 as the Boston Academy of the Sacred Heart.

It was the twentieth Sacred Heart School to open in the United States, and is a member of the international Network of Sacred Heart Schools, which spans forty-four countries and twenty-one cities in the United States.

In December 1925 it moved to the Loren Towle Estate in Newton, where the architectural firm of Maginnis and Walsh added a chapel and a four-story school wing completed in 1928.

In 2016 the Kathleen R. Martin Wellness Center was opened and blessed by Cardinal Seán Patrick O’Malley, OFM Cap., Archbishop of Boston on April 26 of that year.

Once a student graduates these goals have hopefully become a form of wisdom and strength from which they can draw on throughout their lives.
