Head of School, Helen Marlette, announces plans to retire
January 12, 2023
Dear SEM Community,
I write today to announce that I will retire as Head of Buffalo Seminary in June 2024. This is not a decision made lightly. I love my job and the opportunity to work with everyone associated with SEM. Over the years, I have been honored to work with remarkable and committed trustees on our Board. They have supported me and my vision in countless ways. SEM students are curious, kind, and talented; the faculty is brilliant and passionate about their work; the administrative team and staff are thoughtful and unbelievably hard-working; the parents are committed and engaged; and SEM graduates care deeply about the school and contribute to their communities throughout the world.
