boarding school

It is my great privilege and honor to lead Berkshire School into its 110th year as we continue to advance our place among the country's finest independent boarding schools. As you visit our website, I hope you gain a clear understanding of all that we offer, and I hope you are inspired to visit campus to experience firsthand the wealth of unique opportunities available to our students.

Since coming to Berkshire in 2005, I have served as dean of academic affairs, math teacher, coach and advisor, and director of college counseling, before assuming my role as head of school. During this time, I have seen the school flourish. Our commitment to academic, artistic, and athletic excellence has led to record numbers in admissions, success and achievement in every corner of our campus, and nearly 90% of our graduates earning acceptances to the most-selective colleges and universities in the country. The talent and dedication of our students has produced INTEL Science Talent Search semi-finalists, primary authorships on scholarly publications, Scholastic Art Award national medalists, New England Championship athletic teams, and inspiring theater and music performances throughout each year.

As importantly, Berkshire continues to fulfill its longstanding commitment to foster an enduring love of learning in all our students. For school and for life. Our teachers make learning relevant and real, harnessing the intellectual curiosity of our students, extending our classroom walls through technology and the embrace of our unique setting, while ensuring that our students successfully navigate the increasing global complexity of their current and future lives. Berkshire's faculty is a particular strength of the school, and ours works tirelessly to support and inspire our students every day, believing unequivocally in the limitless potential of young people so that they can believe fully in themselves.


I hope you will visit us under the Mountain to see firsthand the extraordinary opportunities available to our students and to meet the people that make up this diverse and vibrant community.Throughout my time at Berkshire, my fondest moments of school life have always been my interactions with students, since it is their triumphs, their ever-evolving interests, and their hopes that ultimately define the success of our school. Students are known well at Berkshire, and our rigorous and intentional commitment to community lies at the foundation of our equal commitment to excellence. We hold our students to the highest standards of scholarship, character, citizenship, and personal growth, and our students eagerly embrace these challenges while also looking beyond themselves to celebrate the successes of others. In this way, Berkshire has forged a unique culture that balances ambition, achievement, and humility in powerful and lasting ways.
