William (Bill) Mazo, 90, formerly of Westport, passed away peacefully on September 22, 2025, at Mozaic Senior Life, surrounded by family. He was the devoted husband of the late Doba Mazo and long-time partner of Lucy Ullmann of Weston.

Bill was the father of Lisa Greenberg (Jim) and Gary Mazo (Gloria), and grandfather of Ari Mazo (Sami), Dan Pipe-Mazo (Jenn), Sara Nanchanatt (Alex), Michael Greenberg (Beth), and Sam Greenberg. He is also survived by three great-grandchildren: Ben, Adi, and Nolan.

A 1957 graduate of Rensselaer Polytechnic Institute with a degree in Civil Engineering, Bill had a distinguished career at Bethlehem Steel’s Ship Building division, Xerox (in both Rochester and Stamford), PepsiCo, Olympia & York, and Sordoni Skanska. He notably served as Project Manager at Olympia & York for four years on the Canary Wharf  Global Financial Center construction project in London, where he also embraced the city’s arts and restaurant scene.

Bill enjoyed boating, fishing, and especially golfing at Westport’s Longshore Golf Club, including several golf trips to Scotland. He will be remembered for his warmth, wisdom, and dry but gentle humor.
