Mancini Duffy is firmly rooted in 1915, when Thomas Bruce Boyd Architect was founded in New York City. After changing its name to Halsey, McCormack & Helmer, the firm went on to design such famous landmark buildings as the Williamsburgh Savings Bank, the firm garnered numerous accolades over the years for its impressive bank headquarters buildings which helped define the greater New York skyline.

Our architects and designers draw upon this legacy and couple it with leading-edge ideas, best-in-practice methodologies, and individual expertise to produce the dynamic and innovative workforce we have today.
