The new Lenox Hill HealthPlex, at 12th St. and Seventh Ave., in the renovated former St. Vincent’s Hospital O’Toole Building, was dedicated in a ceremony on Wednesday morning. The $150 million facility includes the city’s first freestanding emergency department — with no hospital beds on site — which will operate 24/7, 365 days a year. This first part of the HealthPlex will be opening next week, possibly Tuesday, according to a North Shore-LIJ Health System spokesperson. More parts of the HealthPlex will be coming online in the near future. In the photo above, at the ribbon-cutting, from left, were Glennda Testone, executive director of the adjacent L.G.B.T. Community Center; state Senator Kemp Hannon, chairperson of the state Senate Health Committee; Borough President Gale Brewer; Assemblymember Deborah Glick; state Senator Brad Hoylman; Dr. Eric Cruzen, the HealthPlex’s director of emergency medicine; Alex Hellinger, the HealthPlex’s executive director; William and Phyllis Mack, the philanthropists whose names adorn the building; Michael Dowling, president and C.E.O. of North Shore-LIJ Health System; Mark Claster, chairperson of NS-LIJ’s board of trustees; Assemblymember Richard Gottfried, chairperson of the Assembly Health Committee; and City Councilmember Corey Johnson.
