MEC History

It All Began

In 1956, Jon McClure founded McClure Engineering Company in Jefferson, Iowa. The following year, he partnered with Don Culver, creating McClure & Culver Consulting Engineers.


McClure and Culver parted ways. While Culver remained in Jefferson, Jon sold Tom Niles 20% of his company and they relocated McClure Engineering Company to Fort Dodge, Iowa, where we remain a strong community partner to this day.


Mike Trotter started his career with MEC in 1966. He continued his education and received his Master’s Degree in 1979.

In 1968, McClure Engineering Company moves from their office into the historic Isabella House in Fort Dodge.


MEC moves again into our current Fort Dodge location. The building, built in 1918, was once a hotel, famous for being the last place Buddy Holly stayed a few nights before his death.


Terry Lutz and Brent Johnson join the firm.


MEC opened its doors in the Des Moines Metro Area in 1986. With a small staff, Chuck VanGilder relocates to Altoona, Iowa to operate our second office location. Soon to follow a third office was opened in the Iowa CIty area, expanding MEC’s reach across the state.


By the early 2000s, the company was ready to expand again-this time South. MEC opened its Lake Ozark, MO location to serve communities in the Lake of the Ozarks Region.


MEC opens a new office in Sioux City, Iowa in April 2014.


MEC merges with Trabue, Hansen & Hinshaw Inc. (THHinc) of Columbia, Missouri. The combination of McClure Engineering Company and THHinc brings together two well-respected, Midwest engineering firms each with unique specialties to offer clients and the communities they serve.


MEC merges with JFSCO Engineering of Red Oak, Iowa. This merger adds significant strength to the firm’s rail and transloading facility design engineering expertise. It also expands the company’s resources in the southwest Iowa marketplace in surveying, aviation and municipal engineering.


MEC opens a new office in St. Louis, Missouri to expand coverage in the Missouri market.


Paul Trombino III, P.E. joins MEC as President.


Troy Jerman, P.E. joins MEC as Vice President of Transportation.

Looking Forward

To better serve our clients and customers, over the years, MEC has strategically located our offices across Iowa and Missouri. We look forward to strengthening the relationships we have establish with our current clients and building more throughout the Midwest.
