About Greenvale
Greenvale is a hamlet in the Town of North Hempstead and the Town of Oyster Bay, Nassau County, New York. Its population at the most recent census was roughly 1,904. A small community, and discretion matters more here than anywhere. Work is conducted so that neighbors never become aware of it.
North Hempstead covers the Gold Coast and the North Shore commuter belt. Casework skews toward asset verification, estate and inheritance disputes, high-net-worth matrimonial matters and diamond and jewelry valuation.
