a Message from our Head of School
San Antonio offers a wide array of educational opportunities, but I am proud to say, Keystone School stands apart. For more than 75 years, Keystone School has been recognized as one of the top independent schools in Texas and the United States.
Keystone has a well-earned reputation for our accelerated academic program. We inspire our bright, eager students with a challenging course of study while supporting them academically and emotionally. Our students thrive on high expectations, and we fuel those. We also frame failures as opportunities to stretch their abilities. In this way, we help students develop their intellectual capacity and their resilience.
Our talented faculty and staff are deeply committed to students’ academic achievement and personal well-being. Our holistic approach emphasizes the intellectual, ethical, emotional and social lives of our students as they grow from preschool to young adulthood. Wellness is integral to the Keystone experience, through attentive counseling, behavioral guidance, mental health programs, and more.
Rounding out the educational experience are creative endeavors, athletics, community service and leadership development. We teach students to combine the knowledge of the head with the ethical growth of the heart to be peerless academicians and people of good character. Keystone graduates are ready to achieve excellence in their chosen fields, with the ability to inspire and change the world.
This captures the Keystone difference–a high-level academic program in a kind, supportive setting that guides children and adolescents to be the best students and the most caring people they can be. We see the potential in every student here, and we look forward eagerly to observing who they will become.
We hope you will consider Keystone School. Ours is a healthy, high-achieving learning community.
With great expectations,
William B. Handmaker
