Brunswick High School principal Art Abelmann resigned abruptly Tuesday after less than a year on the job — and less than two years after resigning as principal of a Colorado high school.

Brunswick Superintendent Paul Perzanoski received Abelmann’s resignation Tuesday, which was his last day on the job, Assistant Superintendent Greg Bartlett confirmed.

Abelmann, of Topsham, couldn’t be reached for comment.

When asked if Ablemann was the subject of disciplinary action during the year, or whether he was forced to resign, Bartlett said, “no comment.”

Abelmann was injured in a motorcycle crash on Sept. 11, 2012, at the intersection of Maine Street and Maquoit Road in Brunswick. He was not wearing a helmet and no one else was hurt, Deputy Chief Marc Hagan of the Brunswick Police Department said Thursday. Abelmann has not been the subject of any criminal investigations during the last year, police said.

Bartlett said he had not seen Abelmann’s letter of resignation and did not know what it said.

Perzanoski made the announcement in a letter to parents Wednesday.

“Mr. Abelmann has moved on for personal reasons and we wish him well in his future endeavors,” the superintendent wrote.

Perzanoski is on vacation Thursday and Friday and was unavailable for comment, Bartlett said.

The school board accepted Abelmann’s resignation during a budget meeting Wednesday night. There was no public discussion of the resignation, said bchool board chairman Jim Grant.

The board “went into executive session, we read that he was resigning, we came out of executive session and accepted it unanimously,” Grant said.

The move, it seems, caught many unaware. Grant doesn’t know the circumstances surrounding Abelmann’s resignation in Colorado.

Assistant Principal Donna Borrowick will serve as acting principal.
