Nassau County
Nassau County
Nassau County is the inner-ring Long Island suburb of NYC, anchored by Mineola (county seat) and the Town of Hempstead (most populous township; village of Hempstead is the largest village). The economy mixes finance and professional services, healthcare (Northwell Health HQ, NYU Winthrop), Hofstra University, retail, JFK / LaGuardia airport-adjacent logistics, and Long Island's strongest single-family suburban housing market. The County Clerk (Maureen O'Connell) operates from 240 Old Country Road.
