Head of School Welcome

It is my great privilege and honor to lead Berkshire School as we continue to advance our place among the country’s finest independent boarding schools. 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.

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-percent 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 you will find throughout our website, Berkshire offers a forward-thinking college preparatory curriculum, emphasizing both the critical skills required for success in the ever-changing world that our students are entering, and the content to ensure that they leave us with a broad base of knowledge in all disciplines. Our goal, however, is to ensure that every student has a unique learning experience that is both dynamic and relevant. Berkshire’s signature programs – Pro Vita, Advanced Math/Science Research, Advanced Humanities Research, the Ritt Kellogg Mountain Program, Independent Study and Aviation Science – are designed to expand minds and broaden horizons. It is here where students find their passions while distinguishing themselves in an increasingly competitive college process. Our talented, committed and engaged faculty inspire students to find these passions and to strive to reach their full potential every day.

Our motto, Pro Vita Non Pro Schola Discimus – “Learning-not just for school but for life”– implores us to make learning relevant, to provide opportunities for real-world experiences and to create programs that will inspire lifelong passions. 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.
