The Lexington Jewish Leisure Group was formed in 1972 by members of Lexington’s Temple Emunah and Temple Isaiah to serve as a social group for older and retired Jewish people. After the Group affiliated with the Golden Age Council, a service of the Associated Jewish Community Centers, in 1972, it would also hold meetings at Belmont’s Temple Beth-El. The Leisure Group organized outings and activities for the Jewish senior citizens of the area.
