At the turn of the 20th century – before American women had won the right to vote; before a woman was elected to Congress or the Senate – a recent Stanford graduate named Mary Lockey had the commanding vision to open an all-girls college preparatory school. Founded in 1907 with the support and mentorship of Stanford’s then-president David Starr Jordan, Castilleja School remains to this day the only non-sectarian all-girls middle and high school in the San Francisco Bay Area. Through a world-class education – Lockey imagined – girls and women would be empowered to take their rightful place as leaders in society.
