The Martha's Vineyard Times Three vie for two selectmen seats in O.B. Longtime Oak Bluffs selectman Greg Coogan is not seeking a seventh term. Three candidates are seeking two seats open on the Oak Bluffs board of selectmen, as longtime selectman Greg Coogan will not seek re-election. Nominations closed earlier this week. Coogan, who has served on the board since 2003, is a retired Tisbury School math teacher of 30 years. Incumbent Jason Balboni is seeking his second term on the board. Balboni is the board’s current chairman. Two other candidates are seeking election to the town’s executive board — Martha’s Vineyard Shellfish Group executive director Emma Green-Beach, and retired Oak Bluffs fire lieutenant and EMT Rich Michelson.
