Bill Hellmuth


Bill Hellmuth, AIA, LEED AP, is HOK’s president, CEO and design principal for the Washington, D.C. office. With nearly four decades of experience, including 25 years at HOK, he is known for his creative design approach, problem-solving ability and client service.

Hellmuth joined HOK in St. Louis in 1991 and was promoted to lead HOK’s office in Washington, D.C, two years later. After more than a decade as design principal in Washington, D.C., he was elected firm-wide president in 2005 and CEO in 2016.

Hellmuth brings special insight on managing the creative process—balancing the art and the business to create the best design solutions and generate the most value for clients. As a strong advocate for sustainable design, he began integrating sustainability into every project long before LEED certification became a benchmark. Today, he uses building science and sustainable design strategies to create high-performance buildings around the world.

Hellmuth has led the design of many landmark projects in the Washington area and abroad, including the 74-story Abu Dhabi National Oil Company Headquarters in Abu Dhabi, UAE, opening in 2016; the National Air and Space Museum Steven F. Udvar-Hazy Center in Chantilly, Virginia; NOAA’s National Center for Weather and Climate Prediction in Riverdale, Maryland; the Chevy Chase Center in Chevy Chase, Maryland; the District of Columbia Consolidated Lab Facility; Greenland Dalian East Harbor Tower in Dalian, China; Rhine Ordnance Barracks Medical Center Replacement in Kaiserslautern, Germany; King Abdullah Petroleum Studies and Research Center in Riyadh, Saudi Arabia; and U.S. Department of State New Office Buildings in Moscow and Nairobi, Kenya.
