Milton Leadership

Dr. Alexandra (Alixe) H. Callen ’88

Head of School

Dr. Alixe Callen, a Milton Academy graduate with extensive teaching and leadership experience in both public and independent schools, began serving as Milton’s 13th head of school in 2023.

A lifelong educator committed to the pursuit of excellence and innovation in teaching, Dr. Callen balances a wealth of experience as well as an ability to look into the future and navigate changes in pedagogy and education. She champions student-centered curriculum development, a collaborative approach to leadership, and enthusiasm for building community across the school’s three academic divisions. Dr. Callen has supported Milton’s intentional, deeply held commitment to building a diverse and inclusive community that fosters an understanding of injustice and a common goal of fair, equitable practices for all.

Independent schools have the power to demonstrate exceptional leadership in education—embracing the cutting edge of teaching and learning while remaining committed to the high academic standards they have held for generations. Dr. Callen strongly believes that the transformative work happening at Milton Academy can and should extend beyond the boundaries of its campus. In 2024, she launched the school’s next strategic planning process with the goals of preparing students to meet the opportunities and challenges of a rapidly changing world.

Prior to Milton, Dr. Callen was head of school at St. George’s School in Middletown, Rhode Island, a position she held from 2017 to 2023. During her time there, she and her team undertook a full-scale effort to review and renew the school’s curriculum to support interdisciplinary and connected learning, prioritizing strong academics and reflecting the latest research in education.

Dr. Callen received her bachelor’s degree in American civilization from Brown University, a master of arts in teaching degree from Brown, a master’s degree in administration, planning, and social policy from Harvard University, and her doctorate from Harvard, where she was elected to the Harvard Educational Review. Before becoming head at St. George’s, Dr. Callen was the upper school director at Lakeside School in Seattle, the principal of Acton-Boxborough Regional High School in Acton, Massachusetts—a 2,000-student public school consistently rated among the best in the state—and assistant principal of Needham High School in Needham, Massachusetts. She has also held leadership, teaching, and research positions through the Harvard Graduate School of Education, the Francis W. Parker Charter Essential School in Devens, Massachusetts, the Sedona-Oak Creek Unified School District in Sedona, Arizona, and the Coalition of Essential Schools. She serves on the Board of Directors at Steppingstone, a Boston-based educational nonprofit dedicated to supporting students from historically marginalized communities with academic, social-emotional, and college readiness programming.

She and her husband, James Bailey, have two sons, Zander and Miles.
