After nearly a decade at Olentangy High School, Principal Tom McDonnell plans to leave to take a job with the Dublin City School District.

McDonnell this week wrote in an email to Olentangy parents that he plans to resign from the district at the end of the school year to become director of student operations in Dublin. McDonnell worked as a teacher and administrator in Dublin for nine years before Olentangy hired him for his current role in 2008.

“While this is a bittersweet letter to write, I take many great memories of my time with all of you with me as I move forward with this next phase of my career,” McDonnell wrote. “I have the highest regard for everyone here in Olentangy Local Schools and have no doubt that the Braves community will continue to excel in the years to come.”

McDonnell’s decision follows the Olentangy school board’s April 13 vote to hire Todd Spinner, principal of Westerville Central High School, as the first principal of Olentangy Berlin High School. McDonnell was one of four finalists for the job of leading the new school, which will open ahead of the 2018-19 school year.

Olentangy spokesman Devon Immelt said the district will launch a search for McDonnell’s successor “as soon as possible.” He said the school board could vote on a new principal for Olentangy High School as soon as May 18.
