Two quotes resonate with her regarding her philosophy of education. “Every student can learn. Just not on the same day or in the same way.” – George Evans; “Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.” – Albert Einstein.  Sara believes that all children deserve to be held to high standards and expectations, and be given the tools and supports to meet expectations and independence to the highest ability possible for them.

Sara is excited to help the students of Sussex Montessori flourish in the Montessori style of teaching, and to learn and grow in a new teaching environment and method. It is these words of Maria Montessori that most resonate with her: “Never help a child with a task at which he feels he can succeed.” For Sara, independence, growth and perseverance are key.
