Plano school trustees have agreed to part ways with the district's superintendent over "differing leadership philosophies."

Board members voted unanimously on Tuesday to accept the resignation of Dr. Brian Binggeli, who was hired in 2015 after being approached by the district's search firm. Binggeli, 58, will begin using personal leave on Wednesday. His resignation will be effective Jan. 31.

A resignation agreement calls for Binggeli to be paid $307,306, which represents nine months of salary and benefits along with unused vacation time, in exchange for terminating his three-year contract early. A payment of $87,306 will be jointly made to Binggeli and a law firm while the remaining $220,000 will be paid into supplemental retirement plans for him.

In brief remarks Tuesday, Binggeli thanked the board for the opportunity to serve and offered glowing praise to the district, its employees and the community. He declined to answer questions from the media and left the board meeting without any further explanation.

A statement distributed at the meeting stated that both sides agreed "it is in the best interest of the district" to reach an agreement now rather than at the end of Binggeli's contract in June 2019 so that he could pursue other opportunities.

The board praised Binggeli for his service and thanked him for all he has done in his brief tenure here.

His resignation letter, dated Tuesday, states that he plans "to pursue opportunities potentially closer to family and I look forward to the future personal benefits that this decision will provide."

Trustees named interim deputy superintendent Sara Bonser to take over his leadership duties effective immediately. Trustees will start the search for a superintendent who will be "focused on fast-paced innovation aligned with the district's ongoing goals to ensure continued improvement in student learning and efficient use of resources," according to the statement.

District spokeswoman Lesley Range-Stanton said Binggeli's resignation is not related to the resignation of board member Greg Myer, who is stepping down after six months "for personal reasons."

"They're totally separate," she said. "The only thing in common is the timing."

Myer was elected in May to a four-year term over incumbent Marilyn Hinton and challenger Trish Patterson. Meyer did not attend the meeting.

Board members unanimously accepted his resignation. They are planning to appoint someone to serve in his Place 6 seat until the next school board election in May 2019. Whoever is elected at that time will serve the remaining two years of Myer's four-year term.

A subcommittee of the school board is expected to put together elements that will be considered as part of the appointment process. Those details are scheduled to be outlined at the Dec. 12 meeting. Applications to fill the board seat will be accepted after that.

Binggeli was hired from Brevard Public Schools in Florida, where he spent six years as superintendent. He was the first outsider chosen to lead Plano ISD in 20 years, having replaced longtime administrator Richard Matkin.

In an email to district employees on Tuesday morning, Binggeli stated he and the board have "entered into a mutual separation agreement." It offered no further explanation.

John Stafford, who attended Tuesday's board meeting, has two elementary students in Plano ISD and serves on a public policy committee with Plano Chamber of Commerce that gets regular updates from Binggeli. Stafford said there was no sign of any problems between Binggeli and the school board.

"It's curious," Stafford said. "Why would he be resigning in the middle of the school year?"

As of Oct. 27, Plano ISD's student enrollment was 53,952.
