NEW YORK CITY, February 17, 2017 – Empire State Realty Trust (NYSE: ESRT) has signed a 26,100 sq. ft. full-floor office lease with Mount Sinai. The long-term lease at 250 West 57th Street will be home to Mount Sinai’s corporate executive offices.

ESRT’s 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.
