Head of School Pieter Mulder has announced that the 2027-28 school year will be his final one leading Berkshire. He will retire following 15 years in the role and more than two decades spent under the Mountain.
Under Pieter’s leadership, Berkshire stands as one of the country’s premier boarding schools, balancing a commitment to excellence with a deeply supportive community. We are in a position of tremendous strength and momentum, anchored by extraordinary people invested in each other and in the values that have defined our school for generations.
With nearly two years to plan for this leadership transition, Berkshire has time to both celebrate Pieter’s impact and to conduct a comprehensive and thoughtful search for our next head of school. The Board of Trustees has selected Isaacson, Miller (IM), one of the country's leading executive search firms, to guide this national search.
