Curriculum Advisors


Putting together strong and relevant professional development courses is a team effort. The members of our curriculum committee ensure that each course will provide a meaningful learning experience for educators. Our primary objective is to maintain high standards in the courses we offer and provide instruction that is relevant to current educational pedagogy.
