School History

Mary Caswell travels across the country to relocate to southern California and start a new life. Within two months of her arrival she starts the St. Margaret's School for Girls.

St. Margaret’s School for Girls flourishes in Pasadena, but Mrs. Caswell recognizes Los Angeles as a burgeoning city and in 1890 moves the school to a new location—the relatively new but empty Marlborough Hotel at the corner of 23rd and Scarff Streets, near the newly established University of Southern California. Adopting the name of its new location, Marlborough School comes into being. Enrollment increases from the very start, and within a few short years, the site reaches capacity. With the city expanding north and westward, Mrs. Caswell purchases land in the newly opened La Brea tract, and in 1916, for a cost of $70,000, Marlborough School opens at its new site on the corner of Third Street and a “surveyed driveway to be known as Marlborough Avenue."

By the early 1920s and with her health declining, Mrs. Caswell realizes that she needs to prepare for the day when she can no longer lead the School. In 1922, she invites Miss Ada Blake, then head of Louisville Collegiate School in Kentucky, to interview for the position of assistant principal. After journeying across the continent for a one-day interview, Miss Blake is immediately hired for the position, and upon Mrs. Caswell’s death in February 1924, Miss Blake becomes the second Principal of Marlborough School, a position she held for almost two decades. During Miss Blake's tenure, the curriculum expands significantly and Marlborough begins its evolution into a highly regarded college preparatory school, as each year more and more Marlborough students seek and are admitted to east coast women’s colleges. The Student Council is organized in 1924, uniforms become mandatory in 1926, and the School’s first student newspaper is launched, along with many dramatic, literary, and community service-related clubs.

In 1942, Miss Blake is succeeded by Mary Caswell’s daughter, Georgia Caswell Overton, who serves as Principal of Marlborough School for six years. Under her leadership, the boarding division is discontinued, the Honor System is formalized, and, in 1944, the School welcomes the arrival of legendary English teacher Cecil Carnes.

When Mrs. Overton retires in 1948, she is succeeded by Mrs. Helen Mitchell as Principal. Preparing Marlborough graduates for college is a high priority for Mrs. Mitchell, so curricular changes—such as a mandatory four years of English and History, and special honors seminars for seniors—coupled with personal outreach to both east and west coast colleges, results in Marlborough graduates’ placements in the nation’s most distinguished colleges and universities.

With the intention of one day building new School facilities, Mrs. Mitchell and her husband purchase Marlborough from the Overtons. Over the next decade, city building inspections became frequent, and new electrical equipment was way overdue. "The day I knew we had to have a new building was the day I blew a fuse three times in one morning!" said Mrs. Mitchell. In 1960, the Marlborough School Foundation was formed, and the Mitchells generously sold the School to the Foundation, assuring the development of new buildings and ensuring Marlborough's survival well beyond her years as its leader.

The 1960s were transforming times for Marlborough School. With Principal Virginia Jennings (1962-1965) and Headmaster Philip Perkins (1965-1970) leading the School, the newly created Board of Trustees launches the School’s first $4 million fund-raising campaign, “Marlborough of the Future,” to invest in new buildings, campus expansion, and endowment funds. Noted architects William Pereira and Associates create the most modern educational designs while preserving the School’s architectural tradition.

During Mr. Chumbook's tenure, Marlborough expands and enhances campus facilities as well as academic and non-academic offerings and opportunities. The school begins purchasing additional properties adjacent to the campus, and the trustees earmark endowment funds specifically for faculty salaries and student financial assistance.

With a Bachelor of Music degree from Michigan State University and a Master of Music Education degree from the University of Colorado at Boulder, where she also served as an Instructor, Barbara Wagner teaches music in a public school in Michigan for three years. Following completion of a graduate degree program at the University of Colorado and a year as an instructor at the University of Colorado, she joins the staff at Graland Country Day School in Denver, where she serves successively as music instructor, Chair of the Fine Arts Department, Head of the Middle School, Assistant Head, and Interim Head of School.

A native of Michigan, Ms. Wagner comes to Marlborough School in the fall of 1989 as the Director of Upper School, and in 1990 she accepts the position of Head of School. In that role, she expands the academic and extra-curricular vision of the School, as well as its campus, overseeing the construction of Booth Field and Munger Hall, as well as the commencement of the Arden Project.

Marlborough celebrates its quasquicentennial with historical remembrances in the curriculum and in publications, as well as with a "Birthday Bash" celebration on campus.

With the Arden Project, adjacent houses owned by the school are razed and the campus expanded to include a new garden, a full-size, multipurpose field, expanded tennis courts, the Caryll Mudd Sprague aquatics center, the Seaver Pool, a fitness and wellness facility, and additional surface parking. This project completes the current Master Plan for the School and doubles the size of the original campus. 

Dr. Sands joined Marlborough in 2015 from the Springside Chestnut Hill Academy, where she served as President since 2011. Dr. Sands began her independent school career teaching drama and English at her alma mater, the Agnes Irwin School in Philadelphia, where she rose quickly through the ranks, overseeing the community service program, serving as Director of Admissions and Financial Aid, and eventually being named Assistant Head of School. In 1996, Sands was tapped to lead another highly respected girls’ school in Philadelphia, Springside School, and in 2011, when Springside merged with the all-boys Chestnut Hill Academy, the new Board appointed Sands President of the combined institution, Springside Chestnut Hill Academy.

Following the retirement of Dr. Priscilla Sands, Ms. Jennifer Ciccarelli joined Marlborough in 2022 from the Columbus School for Girls, where she served as Head of School since 2014. Prior to that position, she was the Assistant Director/Acting Director at The Winsor School, a highly-regarded Grade 5-12 girls' school in Boston. She was previously the Academic Dean of The Girls' Middle School in the San Francisco Bay area, and spent the first 10 years of her career as a lower and middle school teacher at Greenwich Academy in the New York metropolitan area.

June 3, 2022

The Marlborough Board of Trustees and the Head of School Search Committee are delighted to announce the appointment of Jennifer Ciccarelli as Marlborough’s next Head of School. Ms. Ciccarelli will join the Marlborough community in the summer of 2022, succeeding Dr. Priscilla Sands upon her retirement. 

As we embarked upon this important search process last fall, the Search Committee solicited and received valuable input from the Marlborough community in identifying the key characteristics and capabilities we would seek in our next Head of School. We sought a leader and educator dedicated to excellence in education with a focus on girls’ learning, a demonstrated commitment to equity and inclusion, impactful organizational leadership and management skills, and a belief in the power and importance of collaboration, community dialogue, and intellectual inquiry. 

We were overjoyed to discover all these qualities and more in Jennifer Ciccarelli. Jennifer comes to Marlborough from the Columbus School for Girls in Columbus, Ohio where she has been the Head of School since 2014. Prior to taking that position, she was the Assistant Director/Acting Director at The Winsor School, a highly regarded grade 5-12 girls’ school in Boston. Jennifer was also previously the Academic Dean of The Girls’ Middle School in the San Francisco Bay area and spent the first 10 years of her career as a lower and middle school teacher at Greenwich Academy, another highly regarded girls’ school in the New York Metropolitan area. She earned a B.A. from Wheaton College, an M.A.T. in Elementary Education from Manhattanville College, and an M.Ed. in Education Leadership as a Klingenstein Fellow at Teachers College, Columbia University. Illustrating her distinguished leadership across four girls’ schools, Jennifer’s references spoke of her student-centric approach, her authentic allyship, her passion for educating and empowering young women, and her ability to articulate her vision, tackle tough topics, and build relationships.  

Throughout our search, we were tremendously fortunate to benefit from the active engagement of Marlborough faculty, staff, students, parents, and alumnae. What began with over 200 potential prospects narrowed to a strong slate of seven highly-qualified candidates with a diverse range of skills, experience, and identities. From there, the Search Committee interviewed each first-round candidate for 90 minutes, followed by two-hour hybrid virtual/in-person interviews with the second-round selections. Finally, three finalists were invited to campus for in-person meetings with Trustees and with members of the Senior Leadership Team, Student Council leadership, Alumnae and Young Alumnae Council Leadership, Parents’ Association Executive Committee members and Dr. Priscilla Sands. This thorough and robust process allowed the committee to attract and evaluate the best academic leadership talent.  

Ms. Ciccarelli’s appointment will be effective July 1, 2022, and over the next year we will have opportunities—both in-person and virtual—to meet and get to know her and her family. We look forward to welcoming Jennifer, her husband Chad, and their daughter Perry to the Marlborough community. We will also come together in celebration of and gratitude for Dr. Priscilla Sands’ extensive contributions to Marlborough over her seven-year tenure and look forward to being together in community to do so. 

Until then, we thank you for your support and engagement throughout this process. Our community’s love for Marlborough and its students was palpable and allowed us to attract and secure the right leader for the next chapter of our wonderful school.
