Mount Sinai to Move Corporate Offices to 250 W. 57th St.

NEW YORK — Mount Sinai Health System has signed a long-term lease for full-floor 26,100 sq. ft. office at 250 West 57th St.  The building will be home to Mount Sinai’s corporate executive offices.

The building is owned by Empire State Realty Trust (ESRT) and is located near Time Warner Center and Hearst Tower.

250 West 57th Street has undergone extensive building renovations.  A new Gensler-designed lobby will soon be unveiled, following the new building entrance and retail storefronts, much of which is complete and visible already. Modernization of the building’s elevator system and new elevator cabs will be done later this year.

Mount Sinai is our third full-floor transaction since announcing redevelopment plans,” said Thomas P. Durels, Executive Vice President and Director of Leasing and Operations for ESRT.  “They join a quality tenant roster, including COOKFOX Architects and GuildNet.”

Chris Mongeluzo of Newmark Grubb Knight Frank represented Mount Sinai in the lease negotiations.  Landlord representation was provided by Keith Cody of ESRT, along with Harry Blair and Sean Kearns of Cushman and Wakefield.
