The Porter Square Neighbors Association is a voluntary membership organization of residents and business owners in Cambridge and Somerville. It is open to all who want to work to improve the quality of life in Porter Square and surrounding neighborhoods. Voting members pay dues of $10 per year and must have attended several meetings prior to voting. More detail may be found in the PSNA By-laws. We meet on the third Thursday of every month from 7-9 PM. We have met for years in the North Cambridge Senior Center at 2050 Massachusetts Avenue, but during its renovation, we will be meeting at Lesley University Hall, 1815 Mass Ave at Porter Square in Room 4-037.
