Mount Saint Joseph Academy will merge with Trinity Academy of Newton, with the first classes of the combined high schools beginning in the fall of 2012. While Trinity is co-ed, the Mount has been girls-only since it was founded in 1885. There will be approximately 400 students enrolled in the new institution, which will be called St. Joseph Preparatory School. It will operate on the current Mount Saint Joseph Academy campus on Cambridge Street, Brighton. (photo via Wikimedia Commons)
