As developers who are also building owners, we understand unique challenges and opportunities that range from real estate development, to construction, to restoration, to property management. The Gronen team guides our clients through complex processes and manages all aspects of a project.

We specialize in historic rehabilitation projects seldom approached by other developers. Adaptive re-use of classic but neglected buildings has been a top priority as we invest in neighborhoods and a community’s sense of place. We are also highly experienced in new construction and believe strongly in good design.


Since 1999, Gronen has restored over 2 million square feet of commercial and residential space in downtown Dubuque with development costs in excess of $300,000,000. 

We manage over 1,300,000 square feet of residential and commercial spaces. These various projects have brought new life into the urban areas they inhabit, creating historic store fronts filled with eating establishments, retail and office space, as well as providing space for non-profit organizations that serve the downtown community. Additionally, we offer a mix of Affordable Housing, Workforce Housing, and Market Rate Housing.


These projects have truly been catalytic for Dubuque’s urban core.



"In 30 years, I have built out over 15 centers in various locations, both domestically and internationally. I have to say that working with Gronen was excellent. I found them to be professional, accommodating, and  great to work with. I felt they always had my best interest at heart and worked through any changes or obstacles we threw at them. The move was as smooth as it could possibly be. Frankly, they were the primary reason for that occurring.


I could not recommend Gronen more. I hope we get to work together again."

"Being located in the beautifully restored Schmid Innovation Center has provided us with a unique and vibrant experience.  The progressive nature of this development in context with the rest of the historic buildings in the District lead us to the undeniable conclusion that we had found the perfect setting for Pigott.  We are thrilled to be doing business in Dubuque.  The fact that we ended up where we did and have the opportunity to work with Team Gronen is icing on the cake!"

“As President of the non-profit Dubuque Initiatives, we were presented with a chance to help shape the future of the community by assisting the City in luring a Fortune 25 Company to Dubuque. Faced with the challenge of providing enough space for new prospective employees, we embarked on a journey to identify property, renovate and upgrade the space to fit the needs of a high-tech giant and do it all in less than one-year. We turned to Gronen to complete the project under our ownership and for the tenant needs.

The project team took on the job, planned it according to Federal guidelines and delivered it on-time and on-budget. This was huge for our organization and for the City because of the large investment across many constituents.”

"Gronen is not just the construction management team for Steeple Square, but also a critical partner in our success. They have identified and responded to changing needs, helped us navigate through complex tax credit issues, and personally advocated on our behalf to help secure project funding."

"Gronen was highly recommended to us. After our very first meeting, we knew that we had made the right choice. We have a very busy company and I knew that our CEO and I didn’t have the time to adequately manage this huge project, therefore the services the Gronens offered were exactly what we needed.

Our weekly construction meetings kept me informed of the up to the minute progress and completion dates. I always felt that I knew exactly what was going on and found it incredibly helpful to keep my employees involved in the progress of our new building. The project ran very smoothly, was completed on time and on budget, which is quite unheard of in commercial projects of this size. They were very easy to deal with, treated our employees with the utmost respect, kept the worksite clean and neat and dealt with any problems that arose in a very professional manner.

The attention to detail on this project really gave our building, “that special touch.” Gronen answered every one of our many questions, truthfully and to the point. Kunkel & Associates is sincerely grateful for the integrity, communication, and the hard working ability from each member of the Gronen Restoration team."
