About Upper Brookville
Upper Brookville is an incorporated village in the Town of Oyster Bay, Nassau County, New York. Its population at the most recent census was roughly 1,698. A small community, and discretion matters more here than anywhere. Work is conducted so that neighbors never become aware of it.
The Town of Oyster Bay stretches from the North Shore harbors to the Massapequas. Its casework runs from estate and elder-care matters on the north shore to small-business and family matters in the south.
