Leadership
Paul Masi, a native of Montauk and Harvard GSD alumnus, joined the firm in 1998 after working at Richard Meier & Partners. He brings a refined design sensibility rooted in modernist principles and contextual innovation.

Harry Bates, the founding partner, studied architecture at North Carolina State University and began his career at Skidmore, Owings & Merrill before launching his own practice in New York City. In 1980, he relocated the firm to Southampton, and its current headquarters is in a custom-designed office in East Hampton.
