Leadership

A founding Principal of LEDDY MAYTUM STACY Architects in San Francisco, William Leddy, FAIA, believes that architecture has an important role to play in leading our communities toward a just, carbon-neutral future for all.

For over 30 years Leddy has been a national leader in the design of regenerative architecture that celebrates our place in the natural world. His firm has received over 175 regional, national and international design awards and has been recognized by numerous organizations including the American Institute of Architects, the French Institute of Architects, the Norwegian Association of Architects, the U.S. Department of Energy, and the Urban Land Institute. LMSA is one of only three firms in the nation to have received twelve or more AIA COTE Top Ten Green Project awards – the Institute’s highest award for ecological design excellence. Leddy has lectured widely and served as visiting professor at the Southern California Institute of Architecture, the California College of the Arts, as the Howard A. Friedman Visiting Professor of Practice at the University of California, Berkeley, and as the Pietro Belluschi Distinguished Visiting Professor at the University of Oregon. Leddy was elected to the American Institute of Architects College of Fellows in 2003 and has served on the National AIA Committee on the Environment Advisory Group (as chair in 2013). He is past AIA California Vice President of Climate Action and Chair of the AIA California Committee on the Environment.

LEDDY MAYTUM STACY Architects was the 2017 recipient of the National AIA Firm Award. The firm’s book “PRACTICE WITH PURPOSE: A Guide To Mission-Driven Design” was published in 2023.
