Prospective Families


Dear Parent(s),

Greentrees was founded in 1988 by Marilyn and Murray Hauer.  Marilyn is a NYS certified teacher in early childhood, elementary and special education as well as a school district administrator.  Marilyn spent more than three decades in elementary education and in supervisory positions in Long Island schools before founding Greentrees.  As the Director of Education, she sets the tone and standard of education at Greentrees and puts a strong emphasis on creativity as one of the building blocks of learning.  Marilyn’s daughter, Linda, is the family’s third generation to be involved in education; she is the school’s Administrative Director.

Carefully selected staff members are highly trained, sensitive, enthusiastic and dedicated teachers who provide an enriching, nurturing classroom environment.  Many of Greentrees’ teachers have taught at the school for over 10 years.
Thank you for taking the time to consider the Greentrees Country Day School and Camp for your child.  We are happy to present to you our updated and redesigned website showcasing our school and summer camp.  We encourage you to call our office with any questions or concerns you may have, as well as to schedule a tour of Greentrees.
