Dear Stevenson Community,

On Tuesday, March 1, it was my pleasure to announce the appointment of Phillip Koshi as the upper division’s next dean of students, effective July 1. Mr. Koshi is currently the head of our world languages department, a Spanish teacher, a resident faculty member, and head coach of our girls’ soccer team. He lives on campus with his wife Sarah, who is our director of community education, and their two children, Collins ’33 and Grayson. He joined us at Stevenson three years ago from Taft School (CT), where he served as a class dean, dorm head, and helped develop and teach their health and wellness curriculum. He is deeply respected by our students and his colleagues. I encourage you to watch this video to observe how the news of his appointment was received by our student body.

In his new role, Mr. Koshi will lead a team focused on the traditional elements of the dean’s office’s work, which includes responsibility for the residential and advisory program, health services, and student discipline. He is also charged to develop a comprehensive health and wellness curriculum and provide support for the School’s commitment to equity and inclusion as it is practiced in student life.

The search process, which began in earnest in December 2021, was rigorous and methodical. The members of the search group included administrators and teachers, but could not include students owing to several candidates’ requests to keep their interest confidential in the early rounds of interviews. We received dozens of applications from highly qualified candidates across the United States, and met virtually with sitting deans from independent boarding schools and college administrators. Mr. Koshi was our only internal candidate; it soon became clear to all of the search groups’ members that he was precisely the person the School was looking for.

The opportunity comes about because earlier this year Erik Olson accepted an invitation to serve as the School’s inaugural director of co-curricular programming. In this role, he will oversee our offerings in outdoor education and service learning, and help build related external partnerships. We are grateful to Mr. Olson for his fourteen years of service as dean of students, and look forward to his contributions in this new and important role.


Dr. Dan Griffiths
Head of the Upper Division
