Based in Dubuque, Iowa, Gronen specializes in industrial, new construction, build to suit, and historic rehabilitation projects. With a deep commitment to community-driven development, Gronen has played a key role in the revitalization of their community’s urban core, creating dynamic mixed-use spaces, and fostering significant economic growth. The company’s expertise spans from commercial and residential projects to comprehensive neighborhood redevelopment efforts that balance historic integrity with modern innovation.

In the early 1990s, Gronen built a small team of skilled construction and masonry craftspeople and began rehabilitating homes in the Washington Neighborhood. The company eventually expanded to what we now know as: Gronen Restoration (historic restoration and new construction), Gronen Properties (commercial and residential property management), Gronen Development (guides each client through the all-important early stages of every project), and DBQ Property Group (Real Estate Division). The Gronen team prides itself in building community and setting the standard of revitalization in our urban core and the region.
