Billy Peebles, the longest-serving headmaster of The Lovett School, has announced his retirement.

He has served as the headmaster of Lovett, a private school on Paces Ferry Road in Buckhead, since 2003 and will retire in June 2018.

School leadership praised Peebles’ for his fundraising efforts, doubling student diversity numbers and establishing a new design and innovation school. The Board of Trustees also said Lovett’s free program for low-income minority students, Breakthrough Atlanta, has the largest enrollment in its 20-year history.

The search for Peebles’ replacement is already underway, and the school says they are relying on a search firm and input from staff and the community.

In a letter announcing his retirement, Peebles thanked the city and the school for making his experience as headmaster a positive one. “We have always felt that people across the Lovett community were pulling for us, and that feeling has meant and continues to mean so much to us.”
