Ian Schrager may be the face of the redesigned Gramercy Park Hotel and the eagerly anticipated 40 Bond condo project, but Michael Overington is the force behind those scenes. As a partner in and director of development for the Ian Schrager Company, Overington handles day-to-day project oversight, which includes management of real estate matters both large and small. “I’m Mr. Pusher. Somebody’s got to be the general and kind of lead the troops,” Overington, 52, said.
