Newtown Superintendent of Schools Dr Joseph Erardi has announced his retirement.  The Board of Education is holding a special meeting tonight to discuss the announcement.  Citing a time-sensitive health concern in his family, Erardi said he would stay as long as the Board needs in order to ensure a smooth transition.  Erardi joined the Newtown School District in 2014, and was named Connecticut's 2017 Superintendent of the Year.  The 61-year old says he could not be more proud of the place where he is ending his career.  Erardi most recently oversaw the opening of the new Sandy Hook School, making sure staff, parents and students were comfortable and emotionally ready to move in.
