The Board of Selectmen last Monday appointed four people to the Council on Aging, effective in May. Named were Daniel Benjamin, Lois Jarema Benjamin, Gene Moulton, and Phyllis Hull, a former selectwoman. Jarema Benjamin also serves on the town’s Commission on Disabilities. The four appointees will replace members whose terms expire in May and who are not eligible for reappointment under a Council on Aging policy that limits members to two three-year terms, according to town administrator Stephen P. Maio. The departing members are Robert Curran, Delia Giuffre, Robert Hale, and Viola Simeola. Selectmen also named School Committee member Christopher Callanan to the Permanent Building Committee to replace Richard Hudson, who recently resigned because he took a job with the Massachusetts School Building Authority. Maio said Hudson had to give up the seat because the Permanent Building Committee is helping oversee a project — construction of a new Galvin Middle School — that is being partially funded by the authority.
