We are

  • Leading by example
  • Staying curious
  • Empowering each other
  • Expanding our talents
  • Preparing for college

Our demanding academic and extracurricular programs teach students how to think critically, communicate effectively, and collaborate successfully.

Every student and their parents or guardians receive personalized college counseling, and our graduates consistently report being well-prepared for college. We help students discover their strengths, embrace their challenges, and become lifelong learners.

Historically, schools have suppressed girls’ voices and narrowly defined who they could be.

Our students cultivate their unique voices without fear or other constraints.

At CSG, girls hold every single leadership position. Formal and informal leadership training and opportunities are woven into our four-year curriculum.

Student-driven choice and inquiry are at the heart of our program. Guided by faculty, advisors, counselors, and coaches, students chart a four-year course based on their interests, strengths, and growth areas.

Our community is enriched by the uniqueness of every student.

Relationships are at the heart of Upper School. Students learn best when they are known and respected by their teachers and classmates. We help students build healthy, lasting relationships.

We come together to form a diverse community of learners and leaders. We lift each other up, hold ourselves accountable to one another, and make CSG a joyful, purposeful place. 

We transform students’ lives. It is our goal that every CSG student grows intellectually, personally, and socially during their four years here.
