Mary Ellen Gambon For the past nine years, former Stoughton Select Board Chair Board member Bob O’Regan has tried to place together a jigsaw puzzle of complex pieces for residents and commercial development. In a recent interview with the Journal & Sun, O’Regan, who decided not to run for reelection in the recent Town Election, said he originally was called to public service out of family responsibility. When O’Regan’s son was in the third grade, his best friend left the school system because the family felt the schools were declining. “I looked around and saw there was quite a bit of that going around,” O’Regan said. “When people leave, that’s when you have instability in the community. I’m of the view that the best thing we can do is have excellent schools. And we do that by fixing the downtown and improving the tax base to fund them.”
