CEO | Co-Owner, Mancini Duffy
William Mandara Jr., AIA, is the CEO and co-owner of Mancini Duffy, a national design firm with a 100+-year-old history and tech-forward approach based in New York City. Bill comes from a family in the business: his father and grandfather were general contractors. He got the most thankless tasks during his teenage summers at his father’s job sites. In retrospect, it was a great way to instill understanding and respect for the profession. It was also a not-so-subtle hint from his father that he should be thinking about architecture school instead.
He had been at TSC Design for five years when Mancini Duffy purchased the firm’s assets in 2011, at which point he was named a Senior Associate. He was later named a principal in 2014, became co-owner of the firm in 2017, and was named chief executive officer in 2018.
Throughout his career, Bill’s believed in having consistency of vision and values: that we should never put ourselves or our vision ahead of the client’s. This consistency lets us respond to our clients quickly, with clarity and authority.
Bill lives with his wife and two children in Paramus, New Jersey.
