Casti is a school. An extraordinary one at that. But words can't do justice to everything that it is. It is a journey. It is the passions that you uncover, the best friend you never saw coming, the exposure to new and challenging ideas. Casti is a place where you are comfortable enough to try something different and supported enough to get better at something you love. It is a place of rich history and tradition but also one at the forefront of 21st century education. Castilleja is extraordinary -- and it is preparing you for a lifetime of experiences just as amazing.
