Superintendent Francis Boynton announced that he will retire on Aug. 31.

The superintendent submitted a letter announcing his retirement on May 5 to the Maine School Administration District 40 Board of Directors. He has led the school district for about two years.

Boynton said May 6 that his educational career has spanned 37 years.

“I have given my all to education,” Boynton said. “It’s time for me to look at other horizons before it’s too late.”

He said he has reached the “optimal” retirement age. “It’s been some time coming,” Boynton said. “I felt it was time. I also have a couple personal reasons.”

The announcement came after months of work on a proposed budget by the administration and the school board.

“We each reach a point when the conditions are right,” Boynton said. “That’s the point I’m at. I’m ready to take the next steps.”

The superintendent could be seen at nearly every school function in the past two years. “I very much enjoyed my time in the school district,” Boynton said. “I really wanted to be part of the district.”

Bonnie Davis Micue, the school board chairman, said the board voted to accept the superintendent’s decision to retire.

Boynton was hired by the school board Jan. 29, 2009. His first day on the job was July 1, 2009. He replaced Pamela Carnahan.

Boynton previously was superintendent of School Union 132 in Windsor. He started as a teacher at Millinocket Middle School.
