About Us

jigsaw puzzle

Greentrees was founded and opened in 1988 by Marilyn Hauer. Marilyn has her Masters in Early Childhood education, Elementary Ed and Special Education. For over three decades she has worked as a teacher, director and school district administrator. Linda Hauer, Marilyn’s daughter has worked side by side with her since 1989 and is the third generation in education.

The warm and safe environment has created a foundation and an atmosphere where young children are encouraged to meet their full potential. Here, their curiosities are explored and creative and social skills are cultivated into a lifelong positive experience.

Our enthusiastic, supportive and nurturing staff as well as our teacher-to-student ratio allows us to focus on each individual child.

Our parents and families both past and present along with our solid reputation has kept us committed to each child’s growth in this rich and thriving community. We welcome the opportunity to show you why our program has earned the reputation as being one of the finest pre-schools on the North Shore.

Our Mission

The Greentrees Country Day School strives to help each child grow and develop to his/her maximum potential. We believe that children should grow through a variety of experiences, with challenging activities that encourage each child’s growth physically, socially, emotionally and intellectually. Read More
