Efren Caliva


Efren believes that educators have a moral obligation to build a safe and conducive learning environment in the classroom and on the campus. According to Efren, when students learn at their maximum potential, curiosity and exploration will excel. Students need to feel that they are in a safe place to obtain this new knowledge.

As a leader, Efren strives to lead by example. He would never ask his staff to do something he would not be willing to do. He believes in coaching his staff to reach their full potential.
