    Physical and Health Education Teacher, Head of Year Grade 9

    Abayomi Olushola Koledoye

    A teacher has a powerful influence on children perhaps more than anyone outside the family does. It is the spirit of this realization that Abayomi, popularly known better as "Austin", decided to pursue his Masters Degree in Education with the College of New Jersey in the United States to be professionally qualified to perform this noble role. He considers it as a sacred trust, helping to mold and instill productive principles and values and provide an example to those under his supervision. It is a privilege to have that responsibility and obligation.
