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.

  • A special holiday message from Lise

    This is my final Lise’s Lens of 2022, and I wanted to take a moment to wish you all a holiday break filled with peace and joy. It’s been a busy few months here on campus, and I know the holiday season can be hectic as well (albeit in a different way). Amidst the travel, gathering, shopping, and all the other ways we mark this time of year, I hope you can create a few moments of quiet, finding some time for yourself to reflect on 2022 and dream about 2023. 

    All my best from my family to yours!
