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.

    Happy New Year, CSW! As we turn the page to 2022, I hope to make strides toward a goal I have had for some time now, and that is to engage more regularly with all of you. Through a new series we are calling “Lise’s Lens,” I will be sharing a weekly snapshot of all the things that have excited or intrigued me that week.

    Knowing that everyone’s attention spans are limited these days, the hope is to share very quick, scannable insights into what I have been thinking about — and potentially spark further conversation and connection with all of you! As an added bonus, my kids and husband will be so excited that I have this outlet. Though they are always good listeners, they will appreciate that I have another audience to share these bits and pieces of all the things in my head!
