Lori Ash, Early Childhood Director

Morah Lori Ash has been in Early Childhood Education for over 25 years. Lori believes that Early Childhood educators are extremely fortunate to be on the ground floor of a child’s emotional and academic future. The most powerful tool we can give our youngest learners is the power of play! Play in conjunction with developmentally appropriate academic goals helps to set children up to be critical thinkers, risk takers, scientists, mathematicians, orators, writers and good citizens of the world.  As the late Rabbi Jonathan Sacks wrote “Education means teaching a child to be curious, to wonder, to reflect, to enquire. The child who asks becomes a partner in the learning process, an active recipient. To ask is to grow.”  Lori believes in collaboration - among teachers and children and her greatest joy is spending time in the classroom with the children.  Lori began her career as an Early Childhood classroom teacher and then spent 13 years as the Early Childhood Director of the Ramaz School in Manhattan. Lori taught a Methodology of Early Childhood Education at Touro College. She holds a master’s degree in Early Childhood Education from Hunter College.
