Castilleja School

Castilleja School Castilleja is an independent 6th - 12th grade girls' school in Palo Alto, California, founded in 1907

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 onl

y 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.

Welcome back—especially to our 7th, 9th, 10th, and 11th graders, who were all away on retreats everywhere from Camp Ocean Pines, Redwood Glen, Monte Toyon, and Yosemite! They strengthened friendships and built new connections while they learned archery, climbed ropes courses, and shared stories and s’mores around the campfire. 🏕️

The Castilleja 6th graders are at it again with Sarah Barnum’s science classes and Nick Jerrold’s math classes pulling out the power tools and getting to work!

Mr. Jerrold says, “This year, the project has a particularly nice Casti Village connection. Our 6th graders will be working in small groups—measuring, drilling, assembling, problem-solving, and collaborating—to build cubbies for use around campus.”

Milestones matter in Middle School at Castilleja. This week, 8th-grade students took part in a Youth Purpose Summit to prepare for their DC trip, for writing their 8th grade speeches, and for becoming the leaders of the Middle School. The program created a space for Castilleja’s Middle School students to share stories that matter to them to help identify their strengths and unique gifts. From there, each student crafted a “Purpose Statement” to continue to think about ways to effect positive change in the world—sometimes through a splash, sometimes through a ripple, and sometimes through a thoughtful whisper. In the process, they heard from two alums, Abigail Krenz ‘22 and Gwen Cusing ’17, about how their time at Castilleja helped them identify their spark and follow their passions after graduation.

Today we remember the life of a revolutionary—writer, activist and feminist, Gloria Steinem. Castilleja students heard from Ms. Steinem in person three times over the years, and during her 2009 visit, she shared, “Feminism is just as relevant today—if not more so—as it ever was. Don’t lower your standards. Ever.” Now, almost two decades later, her words hold true—feminism is as relevant as ever AND young women can and should continue to imagine a future rooted in equity, justice, and liberation.

The juniors recently learned where they will be going and what they will be studying on their Global Investigator Trips (GIT) in January. The choices are:

🇮🇩Indonesia to learn about art, culture, and social innovation

🇲🇦Morocco to examine the relationship between tradition and power

🇩🇴The Dominican Republic to explore land, heritage, and community

The GIT experience is an essential part of a Castilleja education, asking students to explore with curiosity and empathy and bring new perspectives to their learning and leadership.

Today is Women’s Equality Day, commemorating the 1920 certification of the 19th Amendment, granting American women the constitutional right to vote. This was a momentous step toward fulfilling the democratic ideals that our country was founded upon. Maybe you’ve heard more about the lives of the Suffragette Movement’s leaders from the Tony-Award-winning musical Suffs, which explores the power of collective action and emphasizes the importance of continuing to fight for equality.

But did you know three Castilleja alums, sisters Julie Cohn ’05 and Marion Cohn ’08 and Morgan Jones '09 were producers of the show? Julie says, “We were drawn to the project by the strong female friendships it's rooted in and the critical political struggle it gives voice to. It felt cathartic, even as it portrayed the frustrations and challenges women have faced for centuries in their battle for rights.” When thinking about the messages Castilleja students can take away from the musical, Marion says, "Relevance, relevance, relevance. Always with historical stories, the question comes down to how much has changed and how you feel about that as you look toward the future.”

Castilleja students just began a new school year, and together with their teachers and peers, they will continue to learn from the past to keep making our democracy stronger.

Classes are underway in Casti Village! In his very first chemistry classes at Castilleja, Mr. Fasano made reviewing lab equipment and safety procedures much more fun by covering those concepts in the context of a very groovy lab. Students created their own lava lamps using only water, cooking oil, dye, and Alka-Seltzer. Chem class this year is going to be lit!
