Theodore S. Hammer, FAIA


In the last five years, Mancini Duffy has gone from a firm almost exclusively focused on corporate interiors to one with a robust architectural practice—and Ted Hammer has been a prime mover in this enormous shift.

He came to our firm in 2012 after having served as the managing partner of HLW, having helped it grow from a regional architecture/engineering practice to a full-service, international firm. Deploying his many years of experience in large-scale base building, interiors, and masterplanning projects all over the world, along with the relationships he’s cultivated over the years with many of the tri-state area’s most important developers, Ted has forged the connections that’s made much of our most exciting new work possible.

Ted has been instrumental in directing design and management services that respond to the individual business strategies of clients. Throughout the industry, he is widely respected for his client-centered approach, outstanding design, and a sophisticated understanding of technological innovation.

Ted was named President of our firm in 2013, and Chairman in 2014. A leader within the industry as well, Ted is involved in the American Institute of Architecture: he is a former Committee Chairman for its New York chapter; he was also elevated to the AIA College of Fellows in 1996. Ted also sits on the board of The Historic House Trust of New York City and is a founding director of the Real Estate Division of the Diabetes Research Institute.

Ted lives with his wife in Connecticut.
