"He is always ready and willing to try something new. He is one of two teachers piloting the accelerated math program, he is on the technology committee and on the peer assistance review panel and does after-school tutoring.
"He has the energy of a first-year teacher," Hester said. "Words to describe him are fairness and respect for students, parents, colleagues and support staff."
