About

Mancini has a history that spans over 110 years, evolving from a traditional architecture firm into a technology-driven design studio with a focus on innovation and collaboration. Originally founded as Thomas Bruce Boyd Architect in 1915, the firm later merged with Halsey, McCormack & Helmer, the architects behind iconic New York landmarks such as the Williamsburgh Savings Bank. By the mid-20th century, the firm had established itself as a leader in corporate interiors, commercial architecture, and workplace design, serving major financial institutions and Fortune 500 companies. Re-branded in the 1980s as Mancini Duffy, the firm expanded its expertise in planning and interiors, laying the foundation for future decades.

Today, we are simply known as Mancini.

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.
