Founded in 1961, MassBay currently serves more than 4,400 full-time and part-time students on its three locations: Wellesley, Ashland, and Framingham.

MassBay offers more than 70 degree and certificate programs[1] aimed at helping students transfer to a four-year college or university or towards direct placement into a career.

MassBay opened with temporary campuses in Watertown, in a property leased from Raytheon Company, and Boston, and at the time served just several hundred students.

In 1975, the college moved to its permanent location in Wellesley Hills, on the campus of the former Elizabeth Seton High School.

In 1990, MassBay opened a second campus in Framingham, which currently houses its health sciences and human services programs.
