Who We Are

The Keystone Mission

Keystone’s mission is to offer an accelerated PK3 – 12 curriculum that provides motivated students with a nationally recognized, well-rounded educational experience in a supportive, inclusive environment that encourages academic excellence, ethical growth, community involvement, and responsible leadership.

The culture of Keystone is at the heart of what makes our school unique. Keystone’s culture promotes self-discipline, individual responsibility, civility, mutual respect and personal honor.

We inspire bright and motivated students with challenging coursework while supporting them academically and emotionally. We round out their education with creative endeavors, athletics, community service and leadership building to produce young people who are ready to achieve excellence in their chosen fields, with the ability to inspire and change the world.

We thrive on challenge and see failures as opportunities for growth and stretching our abilities. In other words, intelligence isn’t something people are born with, but something people develop.

We celebrate our differences and engage in honest discussions where we disagree with civility and respect.

We approach classwork with an accelerated curriculum that goes beyond the idea of utilizing higher-level textbooks. Beginning in kindergarten, we seek students who demonstrate a natural inquisitiveness; in our Upper School, we encourage students to maintain that child-like curiosity, teaching them how to frame questions, find answers, and think broadly. As a result, the quality of work that our students produce is exceptional.

When students complete their educational experience at Keystone, they are ready for the next phase of their education and success in life.

Position: ​Director of Enrollment Management

Education: ​BA in Sociology from University of Southern California

What did you do before you came to Keystone: ​I’ve been in admissions for 14 years but all in California. Before I relocated to San Antonio in July I was the Director of Admissions at a progressive Mandarin immersion school in San Francisco.

Why do you like working here: ​The minute I set foot onto Keystone’s campus it just felt like home. The warmth that is exuded on a daily basis only makes my job that much easier when talking to prospective families.

Something (personal or professional) you’re proud of: ​I’ve never lived anywhere except CA. The biggest move I ever made in my life was from Southern California to Northern California (ha ha). The fact that I’m living in a part of the country I never imagined is quite astonishing. The fact that I really like it and am thriving is even more astonishing!!!!

Favorite/inspirational book: I’m the type of person who doesn’t have a favorite because there are just too many good things and experiences out there. However, one book that has stuck with me and I think about quite often is “A Little Life” by Hanya Yanagihara. ​

Favorite quote: “When life itself seems lunatic, who knows where madness lies? Too much sanity may be madness. To surrender dreams–this may be madness; to seek treasure where there is only trash. And maddest of all–to see life as it is and not as it should be.” –Man of La Mancha
