Willson Aguilar's Response:

I believe that any student from any background can achieve great things. I teach at South Central Los Angeles where crime, divorce and chaos exist, however, there is no excuse for failure. I come to work everyday expecting the best from each individual and the students know that. I challenge them to the limits and they respond to the challenge. My students know I care for them, and that I respect them as people.
