HOK was established St. Louis, Missouri, in 1955. The firm’s name is derived from the surnames of its three founding partners: George Hellmuth, Gyo Obata and George Kassabaum, all graduates of the School of Architecture at Washington University in St. Louis. The design firm started with 26 employees and its three founders.
HOK now is a global design, architecture, engineering and planning firm.
Since our founding in 1955, we have used design to enrich people’s lives and help organizations succeed. Our 1,800 people collaborate across a network of 25 offices on three continents.
HOK’s mission is to deliver exceptional design ideas and solutions for our clients through the creative blending of human need, environmental stewardship, value creation, science and art.
Our design solutions result from a collaborative process that encourages multidisciplinary professional teams to research alternatives, share knowledge and imagine new ways to solve the challenges of the built environment.
These values guide everything HOK does for our clients:
We create exceptional environments that meet our clients’ most complex design challenges.
We inspire people through our work by expressing timeless cultural, organizational and personal values.
We connect people and place with ideas that come from many minds and imaginations.
We care about serving our clients, enriching lives, improving communities and protecting our natural environment through design.
HOK also has completed the acquisition of Kansas City-based 360 Architecture, a 200-person firm that is a leader in the design of sports, recreation, wellness, entertainment and mixed-use facilities and the two firms work as one.
