WASHINGTON, D.C. — After a 32-year career at HOK and 44 years as an architect, Bill Hellmuth, FAIA, LEED AP, announces that he will retire in April 2023, just ahead of the firm’s annual shareholder meeting.

Hellmuth is currently on medical leave. HOK executive committee members Eli Hoisington, AIA, LEED AP, Design Principal in St. Louis, and Susan Klumpp Williams, AIA, LEED AP, Managing Principal in Washington, D.C., are serving as interim Co-CEOs leading the firm’s design vision, business strategy, and day-to-day operations until Hellmuth’s retirement.

Hellmuth joined HOK in St. Louis in 1991 after spending his early career with Skidmore, Owings & Merrill (SOM). In 1993, HOK Cofounder Gyo Obata tapped Hellmuth to lead HOK’s Washington, D.C., office. In 2004, he joined the firm’s executive committee and was named HOK, Inc. President a year later. Hellmuth became CEO in 2016 and Chairman in 2017.

“It has been the greatest honor in my life to lead a firm doing such innovative design work across the world,” Hellmuth said. “We continue to grow and design a diverse range of projects that are important to society. Knowing what we do matters is very fulfilling for designers. HOK has a warm culture that doesn’t exist at every firm. I have great confidence in Eli and Susan’s leadership, along with the entire executive committee, to continue our focus on design excellence while sustaining our collaborative culture.”

Hellmuth’s work, which has won 29 awards from the American Institute of Architects, has spanned nearly every building type and 20 countries. The U.S. General Services Administration invited him to become a GSA Design Excellence Peer shortly after he directed the design of a confidential headquarters for a U.S. federal government agency in the late 1990s. In 2017, the AIA elevated him to its College of Fellows. In 2018, the University of Virginia’s School of Architecture honored him with its Distinguished Alumni Award. Hellmuth has also been a longtime proponent of sustainable design.

Hellmuth’s project portfolio in the Construction area includes the National Air and Space Museum Steven F. Udvar-Hazy Center in Chantilly, Virginia; District of Columbia Consolidated Forensic Laboratory in Washington, D.C.; Walter Reed National Military Medical Center Hospital Renovation in Bethesda, Maryland; University of Maryland, Baltimore Health Sciences Facility III in Baltimore; NOAA National Center for Weather and Climate Prediction in Riverdale, Maryland; and more.

“I can confidently say that I have never met an architect who is Bill’s equal in combining design thinking, empathetic leadership, client relations, business development, and business acumen,” said HOK President Carl Galioto, FAIA. “He truly is one of a kind. We wish him all the best in the next chapter of his life.”
