Our Staff


Erin Lyon, Executive Director

Erin Lyon is committed to making the child care center a place for growing and learning in a warm, safe and healthy environment with an emphasis on earth-friendly living and positive socialization. Ms. Lyon brings great energy and expertise to the job. Her experience includes a Directorship at the prestigious Tutor Time Childcare/Learning Center in New York City. She holds a Master's Degree in Elementary Education from Sacred Heart University.

Ms. Lyon trains all staff to teach a hybrid curriculum developed specifically for Little Green Tree House. The curriculum is based largely on the Creative Curriculum, which is commonly used in most pre-school and kindergarten classes, but also includes some components of a theme-based curriculum. Says Lyon, "My main goal is for our teachers to be hands on and to provide a curriculum that can be easily adapted to different ability levels. The research of Jean Piaget, Erik Erikson and Lev Vygotsky, as well as Howard Gardner's theory of multiple intelligences all impact this custom curriculum."
