OUR STORY
The initial D. Grimm, Inc team consisted of seven people, most of whom now make up the management team. The team formed a strong bond, with each member taking over a prominent role in the company’s operations. This strong start is what first established D. Grimm, Inc as a family company—one that genuinely cares.
Our Mission & Approach
With an emphasis on safety, a focus on product quality, and continuous employee growth, D. Grimm, Inc aims to authentically and ethically earn customer and team loyalty while delivering reliable and quality service.
“We rely on a core group of excellent superintendents who oversee a great group of operators and laborers, and they have proven that they will get jobs done without us constantly looking over their shoulders. Our staff, including those who work in our offices, deserve a great deal of credit for our ability to complete any job on time and on budget.”
