"I have personally worked with John and Mary Gronen on various projects for over 20 years. They are astute planners, which has assured that all of the above projects came in on time and on budget. They seek alternate funding sources to fill financial gaps, and they take personal responsibility in all of their projects. In many cases, they serve as project managers, construction managers, and even property managers. Their passion and perseverance has been heralded on projects that have collectively reinvested over $150 million into the Dubuque community. The Gronen team is tenacious and diligent. I am happy to recommend them to you."
