Introducing the YCNS Staff

Maribeth Fay – Director and Toddler Teacher

Maribeth Fay

Maribeth has been the Director at YCNS since 2005. She is very hands-on and has an open door policy, always welcoming feedback and suggestions on how to improve the YCNS environment. Maribeth's love for the school both as an alumni parent and now director truly shows in her dedication to the school.

As a teacher, Maribeth is warm and fun and encourages language development through play with the toddler class. She provides the perfect environment to introduce two-year-olds to the routine of a classroom, where they feel safe and comfortable. She introduces the children to projects that are both creative and academically based all the while encouraging the children's senses and fine motor skills. She will admit she does not mind making messes, which is a great asset in a class of two year olds!

Maribeth and her husband Michael live and raised their four boys in the Yorktown community.
