The Board of Education on Monday night by a 7-2 vote elected Brendan Hayes as its new chairman. A Democrat who has served on the elected body for three years, Hayes “has been a thoughtful leader on the Board of Education,” outgoing Chair Dionna Carlson said during a special meeting held in the Wagner Room at New Canaan High School. Hayes has served as chair of the group’s Education Resources Committee and “was instrumental in updating the Board of Education’s facilities rental policies as well as being a consistent advocate throughout the Board’s budget process,” Carlson said. In addition to Hayes and Carlson, Board members Sheri West, Penny Rashin, Jennifer Richardson, Hazel Hobbs, and Katrina Parkhill voted in favor of making him chairman. Board of Ed members Maria Naughton and Tom Cronin voted against.
