Our Leadership

Marcel Gauthier, Head of School

Marcel Gauthier

Marcel joined Country Day in July 2022 as our 12th Head of School. A dynamic leader and educator, Marcel served as Head of School at Shanghai American School, with an enrollment of more than 2,800 students and two campuses. 

Marcel has extensive experience in school leadership combined with the genuine heart of an educator. He is known for his strategic vision, ability to build stronger institutions, and skill in coalescing communities.

In 2023, Marcel Gauthier started a blog titled "Reflections with Mr. G." Through this platform, Mr. G reflects on pivotal moments that resonate with our school's mission. His insights and perspectives provide a unique window into the heart and soul of Country Day, offering a deeper understanding of the values that unite us as a community.
