Board of Trustees’ Charge to Head of School Dr. Alixe Callen ’88

Dear Members of the Milton Community,

I am thrilled that Dr. Alixe Callen has begun her tenure as Milton’s 13th head of school!

As the Board of Trustees, we seek to align with the head of school on her priorities and also to perform our primary role—which is to partner with her as the leader of the institution—by offering guidance and support as we ultimately hold her accountable for achieving the school’s goals. During a leadership change, it is considered a best practice for a governing board to communicate its “charge” to a new head, setting expectations on both sides for the start of her tenure.

In the interest of transparency—and recognizing that an excellent school is the product of collaboration and effort by all members of the faculty and staff, students, families, and alumni—we share our letter to Dr. Callen, as well as her response to the Board, with the full community.

Alixe has exceptional qualifications as an educator and school leader and I hope you will join me and the Board in the warmest of welcomes as we continue to make Milton Academy the best possible community for our students.

Alixe Callen ’88 Appointed 13th Head of Milton Academy

We are thrilled to announce that Alexandra (Alixe) H. Callen ’88 has been selected by the Board of Trustees to be Milton Academy’s 13th head of school, effective July 1, 2023.

Dr. Callen, a Milton graduate with extensive teaching and leadership experience in both public and independent schools, currently serves as the head of St. George’s School in Middletown, Rhode Island, a position she has held since 2017.

During her time at St. George’s, Callen 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. In collaboration with the school’s most veteran faculty, Callen formed the Senior Teaching Cadre and has energized pedagogical and professional development through dedicated programs for teaching and learning. She led the development of St. George’s current strategic plan, campus master plan, and the school’s first diversity, equity, and inclusion strategic plan. Her team also launched the Beloved Community Initiative, a program focused on the history of St. George’s and the experiences of students across diverse identities. Over the past five years, she has also collaborated with the school’s advancement office to raise more than $20 million to support new capital projects, including two new turf fields and the restoration of the Memorial Schoolhouse. She has overseen all aspects of the school’s operation, including academics, student life, equity and inclusion, finance, advancement, admission, college counseling, and athletics.

Milton Trustees unanimously supported the recommendation by the Head of School Search Committee to hire Callen, following a rigorous search that considered several highly qualified school leaders. Callen’s experience and ability to look into the future and navigate changes in pedagogy and education—along with her focus on student-centered curriculum development, collaborative approach to leadership, and enthusiasm for building community—were among the many positive attributes noted during the selection process. The Search Committee and Milton’s Trustees were additionally impressed with Callen’s motivation to champion 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.

“During our conversations with Dr. Callen, it was clear that building community and fostering positive cultural change are hallmarks of her leadership. Her natural curiosity and impressive listening skills help her craft highly intentional and extremely thoughtful tactics to support meaningful progress. She speaks eloquently and in detail about the pursuit of excellence in teaching and, more broadly, she is deeply immersed in current thinking about educational practices and the future of education. With her sound judgment and inclusive style, Alixe’s enthusiasm for delivering a stellar environment for student learning will permeate all aspects of education and school life, and will help her excel as the next leader of Milton Academy.”
– Claire Hughes Johnson ’90, P’24 ’27; Chair, Head of School Search Committee; Incoming President, Milton Academy Board of Trustees

As part of a long-planned succession strategy, Head of School Todd Bland will remain in his role at Milton through June 2023 and will work hand in hand with Callen and our Board of Trustees to ensure a smooth transition of leadership as his tenure ends.

“Alixe is the right leader at the right time for Milton Academy. She has proven to be a decisive administrator who values collaboration and places students at the center of all her work. I have full confidence that Alixe will continue the excellent progress that Todd has made and continues to make at Milton and I look forward to a bright future for our school.”
– Lisa Donohue ’83, President, Milton Academy Board of Trustees

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. Prior to St. George’s, 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 and her husband, James Bailey, have two sons, Zander and Miles.

We look forward to working with Alixe and Todd as Milton embarks on this exciting new chapter, and we thank the members of our engaged, dedicated, and broadly representative Head of School Search Committee for their diligent and successful effort to recommend our new leader.

A Message From Todd

In June, I will grant diplomas to members of the Class of 2022 who began their Milton careers as kindergartners when I started my own as head of school. These years have afforded me the great privilege of watching them grow from curious new learners into the wonderful young adults who make up our senior class. 

As I think of sending them off on their journey beyond our community, I reflect on my own Milton experience—and think about the future for myself, Nancy, and our family. I have decided that the 2022–2023 academic year will be my final year as Milton’s head of school.

Serving Milton Academy has been one of the greatest honors of my life. Milton is the alma mater of my parents and my children. Our family has been blessed to be a part of this community for the past 12 years, helping to shepherd and evolve this extraordinary school in important ways. We’re a family of educators and Milton has been a powerful symbol of both our home and our vocation.  

The rewards of leadership are invaluable and none is greater than helping to prepare students to do incredible things for themselves and in the world. This has been, and will continue to be, Milton’s greatest accomplishment. Few things have brought me greater joy than my time spent with students and every opportunity I’ve been given to have a positive impact on the life of a child. This is what draws us to education: the gift and joy of growing young minds. Throughout my career, I have found that the best ways to lead a classroom—recognizing and celebrating every person’s humanity and making decisions guided by respect and care—are also the best ways to lead an institution. Our greatest success stories are those students who carry that empathy and compassion beyond Milton.

It is healthy and necessary for leaders and institutions to undergo change, and Milton is no exception. I know that the next head of Milton Academy, with the support of our employees, students, alumni, and families, will usher in the next great chapter in our School’s history. We are poised to take hold of incredible opportunities while harnessing our community’s dedication, innovation, and creativity. Because of its people, Milton is, indeed, exceptional.

I will continue serving in my role through this and the next academic year to ensure that Milton is cared for during this transitional period. Doing so will provide the School the time and attention needed to engage in a comprehensive search process for our next leader. I remain committed to Milton as head of school through June 30, 2023.

Although much has changed since the Class of 2022 entered kindergarten, one thing remains strong: how much I love working alongside the dedicated faculty, staff, and administrators who educate and care for our students, and serving the extraordinary students, inspiring Board of Trustees, amazing alumni, devoted families, and all those who consider Milton their school.

I know that the School will continue to thrive in so many intricate and transformative ways long after I step away from campus. I will always treasure my time at Milton and will forever remain dedicated to its people and mission. 

With deep appreciation and commitment,

Todd B. Bland
Head of School

Posted October 12, 2021

From the President of the Board of Trustees

Thirteen years ago, as a new trustee, my first official vote was to approve the appointment of Todd Bland as head of school for Milton Academy. In many ways, we came to our Milton leadership roles together. In the ensuing years, our School has evolved, positioning it for a bright and successful future. Consequently, it was a bittersweet moment for me when Todd shared that the next academic year, 2022–2023, will be his last at Milton. 

As a head of school, educator, colleague, and friend, Todd has led Milton Academy with optimism and a recognition of the importance of change. Since his arrival in 2009, he has demonstrated an unwavering dedication to the students in our School’s care and to his colleagues on the faculty and staff. Supporting academic excellence through smart investments in faculty development and classroom resources, Todd has also broadened Milton’s reach, encouraging all of us to find purpose in compassion and service to others. He possesses the boldness required to lead a 21st-century school, as well as an openness to differing perspectives and the rare ability to acknowledge the inevitable obstacles that come with leadership today. Central to his philosophy is a foundational understanding of the humanity involved not only in a school like Milton but in the world around us.

Todd’s tenure has seen several milestones: Milton completed its Dare campaign—the most ambitious and successful capital campaign in School history. The campaign raised $48 million for student financial aid, including the establishment of 44 new scholarship funds; supported an increase to faculty salaries and a more robust professional development program; and upgraded academic and residential spaces across campus. We implemented an institution-wide strategic plan to maintain and nurture the best and strongest faculty; have consistently and rigorously renewed our curriculum; and continue to enroll a diverse, multi-dimensional student body. Most recently, we adopted a new diversity, equity, inclusion, and justice strategic plan and vision to ensure that every member of our community knows and feels that they belong at Milton. 

Our campus has changed, too, thanks to pragmatic investments that make Milton more functional and comfortable for the community while emphasizing important areas of pedagogy. We built and opened the Pritzker Science Center, providing state-of-the-art science classroom and laboratory facilities; redesigned and enhanced the Arts and Media Center, responding to evolving student interests and improving spaces for computer science, robotics, and visual arts; built the Berylson turf field; renovated and added residential spaces for students and faculty; and modernized Ware Hall. Projects are underway for the completion of our Cox Library relocation to Wigglesworth Hall in 2023 and a new home for math in 2024.

During Todd’s leadership, Milton’s endowment has grown by more than 180 percent. In addition, through his 12 years as head, our School’s strong financial health has been achieved by responsible fiscal management and sound investments that will allow Milton to meet any moment, evolve for years to come, and serve a diverse range of the best and brightest students from around the world. 

Leadership is incredibly rewarding. It can also be challenging, school leadership especially so—these past two years in particular have not been for the faint of heart. Even on the most difficult days, Todd’s optimism, kindness, empathy, and sincere compassion help to build cooperation and maintain a focus on solutions. His genuine love for Milton’s people has fortified our community as we have navigated complicated issues. In times of crisis—times that could fundamentally harm many institutions—he thinks globally while attending to individuals’ needs, listens intently, and changes course when necessary with humility and grace. I am hard-pressed to recall a single moment in our countless conversations where Todd’s positive spirit and sense of purpose did not make even the most difficult circumstances easier to handle. And for that, I am eternally grateful.

Todd will stay on through the next full academic year. This commitment provides continuity of leadership as the Board of Trustees engages in a comprehensive, global search for Milton’s next head of school; it also maintains momentum on our key initiatives. I am thankful for the dedication that Todd and his wife, Nancy, continue to demonstrate toward Milton. In addition to the deep warmth and positive outlook she shares with everyone she encounters, Nancy Bland has faithfully served Milton in a number of capacities: five years in the Admission Office, and as an advisor, substitute teacher, and caregiver of many. With their children, Nick ’13, Emily ’14, and Maggie ’14, the Bland family has created a welcoming atmosphere for students, employees, families, and alumni. They will remain members of the Milton community long after their departure.

The search for Milton’s next head of school will be led by Trustee Claire Hughes Johnson ’90. She will chair a diverse search committee with members from across our community. To help guide our efforts, we have retained Spencer Stuart, a global executive search firm with an experienced independent-school and higher-education leadership recruitment practice. In addition to the search committee, opportunities will be provided for members of our community—faculty and staff, students, families, and alumni—to participate in the process. We will continue to provide updates as the search process unfolds and will share details on our Head of School Search Committee members by the end of October.

We will all have many moments to connect with Todd as he continues his day-to-day leadership of Milton through June 2023. For today, please join me in gratitude for his service and dedication, and for guiding all of us with his positive, warm, and caring spirit.
