J. Kenny Wieber Jr., P.E., LEED® AP BD+C


Ken Wieber began working for Altieri as an intern. He was made a Principal in 2011 and leads one of Altieri’s four design studios. He has considerable expertise in the design of specialty mechanical systems for architecturally challenging programs such as Steinway Hall and Glenstone Museum, as well as for the modernizing of historic buildings such as the Museum of the City of New York and the Folger Shakespeare Library.

Ken brings expansive creativity to his projects, pushing Altieri’s design philosophy forward by working closely in tandem with his clients. The key relationship between setting client expectations and the ultimate success of a project is a focus of his approach. Ken’s management style emphasizes open communication and a shared goal of achieving the architect’s and client’s vision.

Ken’s portfolio includes many of Altieri’s significant cultural and higher education projects, as well as key residential projects such as a new residence in East Hampton, NY and a penthouse expansion in New York City.

When not designing specialty systems for complex building programs, Ken can be found woodworking or rebuilding a classic Alfa Romeo.
