It is located in the suburban town of Dartmouth, on the south coast of Massachusetts. Stang's campus is 25 minutes west of Cape Cod and 20 minutes east of the Rhode Island border. Its 600-plus student body draws from more than 50 cities and towns in Massachusetts and Rhode Island. Catholic secondary education in southeastern Massachusetts began in the early 20th century with local parochial schools affiliated with various Catholic parishes. Some of these, such as the now-closed Holy Family High School, located near St. Lawrence Church in New Bedford, had strong academic reputations and produced generations of prominent Catholic alumni in the region. While Stang was not the first Catholic secondary school in southeastern Massachusetts, it was the first regional, diocesan, coeducational institution. Founded in 1959, Stang's original faculty included Sisters of Notre Dame de Namur in full religious habit. The new campus across from the Country Club of New Bedford in then-pastoral Dartmouth drew students from cities and towns in a radius from Rhode Island to Cape Cod. In the years following the Second Vatican Council, the number of Sisters of Notre Dame decreased. By the 1970s the vast majority of faculty and administrators were lay men and women, and the remaining sisters dressed conservatively, but in lay clothing. Since its inception, Stang has had a large number of alumni return as teachers and administrators.
