R/M has been Serving Local People
& Solving Local Problems since 1946.



Driven from the housing market boom in the post-World War II era, Ruekert & Mielke, Inc. (R/M) was established in 1946. Founders John Mielke and Frank Ruekert, Sr. started out moonlighting in their houses at night designing subdivisions. As young engineers, John came home from a commission in the Army Corps of Engineers to join Frank, then an engineer with the City of Waukesha. 

Since then, R/M has become the local leader in helping municipalities achieve balance with fiscal responsibilities and infrastructure needs which support the quality of life and make each community desirable as a place to live and work.

In mid-2016, R/M acquired the staff of Kaempfer & Associates, Inc. (K&A), a firm located in the Fox Valley area with almost 30 years’ experience. In the past, K&A has prided itself with performing water, wastewater, and municipal engineering services to many municipalities throughout Wisconsin. During the last several years, we at R/M have had the pleasure of working with K&A with common clients and have been able to witness the commonalities between their firm’s approaches and our own.

With R/M’s acquisition of K&A staff, we will enjoy added expertise in these services areas, greater technical excellence, and an enhanced ability to better serve our clients. With a new office in the Fox Valley area and new staff to utilize, R/M continues to grow and improve our already robust capabilities.



R/M’s commitment is where it matters most – at the local level and to the community. R/M employees aren’t just engineers, financial analysts or technology experts. R/M staff live, work and play in your communities. Our experts have authentic perspective on the daily challenges and expectations in which your residents - their neighbors - want in their municipal services. Spanning across the Midwest, R/M has grown to 6 locations to create long-term client relationships through personalized services and tailored solutions which have proven to save communities both time and money.
