Saint Joseph Prep Information

Saint Joseph Preparatory High School (SJP) opened its doors in September 2012 at 617 Cambridge Street in Brighton. As a sponsored ministry of the Sisters of St. Joseph, Saint Joseph Prep came about as the result of a merger of Mount Saint Joseph Academy in Brighton and Trinity Catholic High School in Newton. SJP established itself quickly as a leader in Catholic education in Massachusetts with a reputation for academic excellence, authentic community, meaningful engagement and dynamic innovation. A much sought after co-educational high school destination, drawing from over 40 towns in the Greater Boston area offering signature programs including, a robust and innovative STEAM and Robotics program, Engineering Certificate, Public Speaking and College Road Programs and Community and Senior Service Projects. After graduating eleven classes of talented, well-rounded students, many of whom went on to attend some of the top colleges and universities in the country, Saint Joseph Prep closed in June 2023.

Mission Statement of Saint Joseph Prep:
