Preschool Director

Mr. Andy Olson has taught in a variety of Christian early childhood programs. What Mr. Olson loves about Christian schools is that children learn about Jesus every day through Bible stories, music, prayers, and through their relationships with teachers and peers. He also enjoys the school-home connection when children take what they have learned about Jesus and share it with their families at home.
