Post Properties, Inc. (NYSE: PPS) is a developer and operator of multifamily communities, including resort-style garden apartments and high-density urban apartments and operates as a real estate investment trust (REIT). Post Properties is headquartered in Atlanta, and has operations in nine markets across the country. The company employs approximately 600 people and owns approximately 20,000 apartment homes. Post Properties was founded in Atlanta in 1971 by John A. Williams and Douglas Bates, and initially developed and managed primarily garden-style apartments. In the late 1980s, Post shifted its focus from garden apartments and began to also explore urban "in-fill locations,” areas in once-vacant urban centers that were beginning to become residential again. In the 1990s, the company also began developing mixed-use properties, combining residential units, retail and, sometimes, office space.
