School History

In 1888, a young teacher from Maine, newly widowed and accompanied by her young daughter and niece, traveled across the country to relocate to California and start a new life. Within two months of her arrival in Los Angeles, Mary Caswell founded what would soon become Marlborough School, now the oldest independent girls' school in Southern California.

Over the century that followed, the school has grown and changed in many important ways. Today's student body is representative of the talent and diversity of greater Los Angeles, academic and athletic programs have expanded, college matriculation is highly competitive and distinguished, and campus facilities have kept pace with the educational innovation taking place inside the classroom.
