Nassau County is covered in full from Suite 325 at 1225 Franklin Avenue in Garden City — the busiest of the five Dan Ribacoff offices for polygraph examinations and domestic casework.
Nassau is made up of two cities, sixty-four incorporated villages and a large number of unincorporated hamlets, spread across three towns: Hempstead, North Hempstead and Oyster Bay. Each has its own page below covering private investigations, polygraph testing, firearms training and diamond and estate valuation.
