A month after his contract was extended, Islesboro town manager Jeff Grossman has resigned, apparent due to conflicts with the board of selectmen.

Speaking on Dec. 23, Grossman, who has served in the position since November 2009, pointed to problems he had working with a relatively new board, describing his decision to leave in the kind of terms people might typically reserve for divorces and other awkward separations.

“There were four new board members and the fit just didn’t seem to be right,” he said. “So I think it’s best for both me and the town to move in the direction that’s appropriate for each other.”

Asked if the problem was related to personalities, Grossman called it “mainly a difference in management style and goals.”

Selectwoman Susan Schnur, who chairs the five-person board and has served on the board for roughly six years, gave a similar account of differing visions between the manager and the newer board members, calling the situation a “perfect storm.”

“It was just one of those things where everybody acted hard-headed,” she said. “The board decided to go in a different direction from the direction that we’re going and it’s just one of those things that you can’t really explain to anybody.”

Schnur said the new board members are still learning their jobs, and in her view, that led to the conflict of styles that prompted the town manager’s resignation.

“But it’s nobody’s fault,” she said. “It’s one of those stupid things, and Jeff resigned. And he was a perfectly competent town manager … there wasn’t a problem there.”

Grossman’s resignation is effective at the end of the year. He currently lives on Islesboro and said he has a lease through May but is not sure what he will do after that or what kind of work he will be looking for.

“I’ve been in city management for 25-plus years and I’m also a registered investment adviser, so I might go back to dealing in investments,” he said.” … I’m just not exactly sure what direction I want to head. That’s it.”

On Tuesday, Jan. 3, the selectmen are scheduled to discuss appointing acting and interim town managers.
