Having spent extensive time in Africa developing and implementing entrepreneurship and permaculture programs has given Arlae Castellanos an out-of-the box approach to problem-solving and addressing sustainability hurdles through creative means. The programs she develops engage the larger school community that helps bridge the relationship between actions and outcomes in environmental systems. Castellanos has taught high school through college graduates on a variety of subjects ranging from energy auditing, solar for the developing world, sustainable architectural design, and entrepreneurship. She melds her capacity to extrapolate schools' needs with real-world applications to manage and develop the Green School Alliance’s premier sustainability tool, START.
