The Mount Sinai School of Medicine has leased a portion of the 17th floor comprising 6,918 s/f of office space at Jack Resnick & Sons' 25-story tower at 485 Madison Ave. Thomas Ahn, vice president of real estate, and Glenn Dawson, real estate asset manager of the Mount Sinai School of Medicine, represented the tenant, while Dennis Brady, executive managing director, and Fran Delgorio, managing director of Jack Resnick & Sons, represented the building's ownership in the 10-year lease. The school, which is headquartered in the Annenberg Building at 1468 Madison Ave., at 101st St., expects to take occupancy of the new offices later this month. According to Brady, the school chose 485 Madison Ave., which occupies the southeast corner at 52nd St. , because of its convenient midtown location and its close proximity to Grand Central Station and mass transit. He said that asking prices in the building range in the high $40s to mid-$50s and only two units are still available - the entire 22nd floor and a portion of the 13th floor. A leader in medical and scientific training, biomedical research and patient care, Mount Sinai School of Medicine attracts outstanding scientists, clinicians and students, all of whom share a deep commitment to expanding biomedical knowledge, providing expert clinical care and serving the community. Working in close partnership with The Mount Sinai Hospital, Mount Sinai School of Medicine serves one of the most diverse and complex patient populations in the world. Jack Resnick & Sons is currently carrying out a major capital improvement program at 485 Madison, which includes the installation of new energy efficient windows, the upgrading and modernization of its elevators, and the installation of new energy efficient chillers for its central air conditioning system.
