Marc Holliday is the CEO and a director of SL Green Realty, New York Citys largest commercial landlord.

The firm controls 61 office properties that cover more than 29 million square feet in the New York metro region, with particularly large footprint in Midtown. There, SL Greens holdings include 1350 Avenue of the Americas, 625 Madison Avenue, 810 Seventh Avenue and 1745 Broadway among many others.

Its tenant roster reads like a Whos Who of corporate America, including major banks, publishing houses and law firms.

Holliday has overseen many of these acquisitions and tenant leases since his ascent to the top spot in January 2004, shortly after which he repositioned the firm to be more aggressive in its deal-making.

He joined SL Green as its chief investment officer in 1998.

Holliday earned a business degree from Lehigh University and a masters in real estate development from Columbia.
