Why Nassau County
Nassau is the densest concentration of mid-market business activity on Long Island. Healthcare clusters in New Hyde Park, Mineola, Valley Stream, and Roslyn. The legal corridor runs through Garden City and Mineola. Financial services concentrates around Lake Success, Great Neck, and Manhasset. Professional services and family-owned businesses are everywhere.
For an MSP, Nassau is the home turf. For a Nassau business, the right MSP is one whose office is on Jericho Turnpike rather than in another state.
