It helps us define the firm we'll become.


Architects Irv Dana and Bill Larson, and engineer Jim Roubal, launched their eponymous firm on April 1, 1966 from a 12-by-12-foot space in a basement at 102nd and Wright in Omaha. The integrated practice was founded on their shared ideals of quality, fairness, opportunity for professional growth, and ownership. Those principles drive our core values today.

The '60s


Marked by transformation and optimism, the ‘60s were a blend of idealism, activism, and undreamed-of technological advances. This era also saw the emergence of a new generation of architects – Dana, Larson, and Roubal among them.
