For those who may not be familiar with Williston Park:
Williston Park is a village (incorporated in 1926) in the center-south part of the Town of North Hempstead, in the west part of Nassau County.
Beginning on the north and moving in a clockwise direction, the Village of Williston Park in the Town of North Hempstead is bordered on the north by the Hamlet of Albertson; on the east by the Village of East Williston; on the south by the Village of Mineola; and, on the west by the Hamlet of Herricks.
Williston Park is one of those villages and hamlets on Long Island where most of the places with the community name in their mailing address are not in the village: places that have a "Williston Park, NY 11596" mailing address that are not in the Village of Williston Park are in the Village of East Williston, the Hamlet of Roslyn Heights and the Village of Mineola.
