Mancini Duffy is a full-service design firm specializing in architecture, planning, and interior design. With offices in New York City and New Jersey, the practice complements its century of expertise with contemporary entrepreneurial spirit and technological skill for clients in the commercial, education, financial and professional services, retail, sports, and tech and media sectors.
Mancini Duffy traces its roots back to 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 landmarks as the Williamsburgh Savings Bank and earned a reputation over the years for its impressive bank buildings that helped define the architectural fabric of greater New York.
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 work we are known for today.
Our leadership is committed to mentoring professional and personal interactions among our staff, as well as contributing to our industry and the wider community as a whole. This dedication is reflected in their involvement with distinguished organizations such as the American Institute of Architects, the International Interior Design Association, the New York Building Congress, the Society of American Registered Architects, and CoreNet Global.
