Welcome from the Head of School

Welcome to The Rivers School

Ryan S. Dahlem is the ninth head of school at Rivers. He arrived on July 1, 2023, having previously served as assistant head of school at St. Margaret’s Episcopal School, a PK–12 school of 1,240 students in San Juan Capistrano, CA. There, he created a unique student-centered Innovation Strategy rooted in design thinking that has been recognized nationally in the world of independent schools. At Rivers, Ryan continues that approach of student-centered learning, built on a foundation of strong relationships and the school’s philosophy of Excellence with Humanity.


"Above all, I value deeply personal relationships between educators and students. They are at the heart of a transformational education."
—HEAD OF SCHOOL RYAN S. DAHLEM
Ryan graduated from Stanford University with an AB in psychology and from the Harvard Graduate School of Education with a master’s degree in teaching and curriculum. He is a trained musician and avid mountaineer who has climbed the highest mountain on each of the seven continents. Ryan and his wife, Anne, have three children: Peter, Ella, and Colin.

Ryan was initially drawn to The Rivers School for its mission, core values, and tradition of Excellence with Humanity, which, he said, resonates deeply with his own educational philosophy. Building on the school’s momentum, he is delighted to lead Rivers into its next chapter.
