Head of School Welcome

It is my great honor and privilege to lead Berkshire School, and I could not be prouder of the community and culture our students and faculty create together here. At Berkshire, we strive to instill the values, critical skills, initiative, and confidence that will ensure our students' success in school and beyond.

During my 12 years of service to Berkshire, the school has grown in transformational and lasting ways, with the quality of our students, faculty and programs never stronger, applications for admission exceeding 1,200 per year, and tremendous support from grateful graduates and parents demonstrating their overwhelming dedication to our community.

Throughout our website, we will introduce you to Berkshire’s unique opportunities and signature programs, which encourage our students to continually reimagine their horizons, to take risks, to discover and pursue lifelong passions, to lead and serve others, and to distinguish themselves in an increasingly competitive college process.

Students and families choose a Berkshire education for an exceptional academic experience that is authentic, relevant, and forward-thinking; for a commitment to character development that is embedded in all aspects of student life; for our strong college and university outcomes; and because we intentionally prepare students for success. Students are encouraged to learn in the words of our School motto: Pro Vita Non Pro Schola Discimus—“Learning, not just for school but for life.”

At the core of our work with young people is knowing them well. We take great pride in knowing each student and his or her journey from their first days on campus to their walk across the commencement stage. Our talented and dedicated faculty serve as teachers, coaches, and advisors, understanding students through each of these lenses, and inspiring their curiosity, their character, and their commitment to reaching their full potential every day.
