R/M was established in 1946 by John Mielke and Frank Ruekert, Sr., who met after John returned from his service in the Army Corps and was hired to work alongside Frank as an engineer for the City of Waukesha. Driven from the post WWII housing market boom, John and Frank began their early partnership moonlighting as subdivision designers, working from their kitchen tables after their full-time jobs late into the evenings.
75 years later, R/M's engineers, environmental specialists, and technology experts remain committed to providing unparalleled planning, design, and construction management services to our clients.
John and Frank’s first big break arrived when the City of Pewaukee enlisted R/M to design the City’s first sewage treatment plant. The firm grew rapidly from that point on, as R/M secured the water, wastewater, roads, and other infrastructure projects necessary to meet the increasing demands brought on by the rapid suburbanization of Waukesha County.
R/M designed much of the first-generation infrastructure for many communities in Southeastern Wisconsin, including the Village of Menomonee Falls, the City of Pewaukee, the City of Brookfield, the Village of Elm Grove, the Village of Sussex, the Village of Hartland, the City of New Berlin, and the City of Muskego. They also designed some of the area’s first business parks, subdivisions, and municipal swimming pools, including those in Hartford, Evansville, Waukesha, and Sun Prairie.
R/M is now on its third generation of ownership. In 1995, R/M transferred 30% of the company’s stock to the employees, and in 2015 the firm became 100% employee-owned. The benefits of employee ownership have paid off, and R/M has been named one of Wisconsin’s Top Workplaces for four consecutive years and counting.
