The story

How Greenvale came to be

From Wikipedia’s history of Greenvale.

Read it all →

Located between Roslyn and Brookville, the Greenvale station is known as the Long Island Rail Road stop for the C.W. Post Campus of Long Island University and the New York Institute of Technology. While LIU Post is located to the east in Brookville, it uses the Greenvale, NY 11548 ZIP Code and the Greenvale Post Office.

Until 1866, the community was known as "Cedar Swamp", and later known as "Bull's Head", until some point in the early 20th century; it has also been known historically as "North Roslyn".

On January 13, 1933, the Greenvale Post Office was established. It moved to its current location in 1976; the original post office location was subsequently purchased by a local business.
