Large blocks of empty retail space left in Long Island’s malls and shopping centers after the exits of Lord & Taylor, Sears and other retailers are providing real estate opportunities for health care providers. They are spending millions of dollars snapping up and renovating the spaces for expansions in so-called “medtail” — medical facilities in retail settings.
NYU Langone Health, Catholic Health, Stony Brook Medicine and Northwell Health are among the providers that have leased former department stores or other large retail spaces where they plan to open new medical facilities in the next 12 months.
