Teaching Philosophy:

“Give a man a fish and he will eat for a day. Teach a man to fish and he will eat for a lifetime.”

I am not here simply to give students an education. I am here to guide students as they grow and be a support in their learning. This is about them, not me. Their growth in high school will directly affect who they become later in life and I want to do all that I can to help students be the best that they can be.
