WESTPORT — Greens Farms Academy’s Head of School Janet Hartwell will retire from the Westport-based private school in June 2018.

“These years at GFA have been so deeply rewarding for me, professionally and personally,” said Hartwell, who has been at the school for 14 years, in a statement released by the school March 1.

Last year’s graduating class named Hartwell as an honorary “lifer” — a term for students who attend the school from kindergarten through to 12th grade — having started with them back in 2003.

“One of the great joys of working with our students is to watch them grow and develop at GFA, finding their voices, passions, and their sense of self,” Hartwell said. “Of everything that I will miss, it is the students most of all. I am immensely proud of them, and they reach me in profound ways through their energy, honesty, and authentic ways of being.”
