Meet Head of School Lise Charlier

Born and raised in Haiti, Head of School Lise Charlier was educated in the Haitian, French, and American educational systems. Her father, Gérard Frédérique, was a Haitian ophthalmologist and her mother, Esther Eshelman, was a Mennonite nurse from a Pennsylvania farming family. 

In her time at CSW, Lise has proven herself to be a capable and accomplished educator, who leads with intellect, patience, positivity, and drive. Her 25+ years of experience as a teacher and administrator is evident in her ability to build relationships, problem-solve, and innovate with creativity and confidence.

Prior to CSW, Lise served as director of studies and strategic initiatives at Severn School in Severna Park, Maryland. Before this role at Severn, Lise was upper school assistant principal at Friends School of Baltimore in Baltimore, Maryland. She has served on the board of trustees for Green Street Academy, the Association of Independent Maryland and DC Schools (AIMS), the Cowles Charitable Trust, and most recently the Center for Spiritual and Ethical Education (CSEE).

She holds an MS in education from Johns Hopkins University and a BS from Georgetown University.

    Hello — and welcome to the first installment of Lise’s Lens of the 2023-24 school year! Lise’s Lens is my weekly blog, which is released every Thursday afternoon with the community newsletter. Take a look to find out what I’ve been reading, thinking about, and watching/listening to.

    To start, here are a few quick facts about me:
    • This is my fifth year at CSW
    • I was born and raised in Haiti and still maintain a residence there, though the very difficult times the country is facing have prevented me from going back for a few years now.
    • I have two grown children, a son and a daughter. 
    • Prior to moving to Weston for my headship at CSW, I lived and worked in the Baltimore area for 23 years, and Pittsburgh, PA, for 5 years
    • I love to garden, cook, read, admire and appreciate fabric and art in general…
    • I spent this summer welcoming students from Taiwan on campus and to the Boston area, admiring all the facilities work happening, being with family in Canada and France and also being inspired by incredible sustainability work being done on Governor’s Island in NYC…
    • My favorite thing about CSW is the people! Colleagues and students, trustees, parents and getting to know more and more alumni every year! This is a vibrant, interesting, curious and innovative caring community! And I get to teach!
