Welcome from the Head

"Welcome to the American School in London, where we offer a singular opportunity to students—the challenge of high expectations, the support of a caring and inclusive community, and the excitement of engaging learning experiences, delivered by a first-rate faculty in one of the great cultural centers in the world.

"I am delighted to have rejoined the ASL community, one that I love and appreciate so deeply. The roots of our history as a school are solid, and the joy and excitement of being a part of the ASL community a privilege. My priority here is to make sure that we recognize and relish the community spirit that has always characterized the School and to face our challenges with optimism and determination. 

"As interim head of school, a key aspect of my role is to guide ASL through the leadership transition, and position the School for success in readiness for our next head to take the reins in summer 2023. In the meantime, rest assured that I am grasping every opportunity to learn about the experiences of parents, faculty and staff, and students.

"At ASL, we have a steadfast commitment to our mission and core values and to the pedagogy we believe in. We are dedicated to being a school that knows, values, and supports each student in our care, and our mission and core values will continue to be our north star.

"London thrives, and our students are taking full advantage of this wonderful city as a classroom, participating actively in its vibrant historical, artistic, and cultural venues. It is our pleasure to introduce our students to the background and experiences that will create the international citizens of tomorrow. 

"Welcome to our school!"
