Upper School ESL & Resource

Sonjia Febrey

Upper School English

John Foster

Over the course of my career, I’ve taught both college and high school students. My first job was at a small boarding school. It was there, I think, that I first understood how vital a strong sense of community is on any campus; it is certainly a quality that makes working at Doane Stuart so rewarding. At the heart of my classroom here is a seminar table, not a lectern; it’s a sounding board for the lively exchange of ideas, and my students make the most of it. In the past few years, I’ve begun writing fiction; more than one of my stories was inspired by my work at DS.
