  • Where students are prepared for lifelong success.

In the Upper School, we pride ourselves in creating an individualized educational experience for each student by identifying and building upon his or her talents and interests. Throughout a challenging four years, our role is to recognize how our students learn best and prepare them to excel at the university level. Every day, we challenge our students to find innovative solutions to complex problems and develop critical thinking skills that will serve them in leadership roles, in their future educational endeavors, and in anticipation of excelling at professions that may not even exist yet.
