A Bumper Crop of New Faculty

The end of Pomfret’s pandemic hiring freeze leads to an abundant harvest.


This fall has brought a bumper crop of new faculty to the Hilltop. After the hiring freeze implemented during the pandemic was lifted more than fifteen individuals were hired as part of the largest new faculty class in recent history.  There are some familiar faces in the bunch with Jackson Lyon ’17 and former science teacher Annie O’Sullivan returning to the campus. Two senior administrators and two admission professionals as well as five science teachers, three math teachers, two history teachers, a Spanish teacher, an English teacher, two learning specialists, and a school counselor make up the newest members of the Griffin family. 

Be sure to say “hello” and introduce yourself as you see them in the hallways, on the field, and in the dorms.
