Kirby School was founded on the belief that a learning environment where students feel respected and appreciated will bolster enthusiasm for learning and encourage scholastic achievement at the highest levels.

In 2019, Kirby School celebrated its 25th anniversary with a renewed commitment to providing a world-class education by undertaking a capital improvement project to build a Recreation Area, with an amphitheater, sport court, dining, and outdoor classroom space.
