Our Focus

Delivering Safe, High-Quality Infrastructure

Wendler is ONE OF IOWA’S MOST TRUSTED BUILDERS OF CIVIL INFRASTRUCTURE.

No other contractor from the state has built more water and wastewater treatment plants over the past half-century, or done more complex engineering-procurement-construction (EPC) work than Wendler. That’s why we are trusted for heavy civil projects of all scopes and sizes.

Our Story

A Legacy of Leadership and Growth

In 1973, Glenn Wendler founded a civil construction company in South Amana, Iowa, naming it Wendler Engineering and Construction.

Small but mighty, the business generated staying power as its staff dedicated themselves to safety, quality, honesty, and family. In 1998, Glenn Wendler retired, and the company appointed Randy Reihmann as President. At that time, the company had begun developing a well-rounded construction fleet, and built a well-respected reputation among communities and developers in the state.

The company became WRH in 2008, and in 2020, Randy Reihmann transitioned to Chairman of the Board as Jamie Rich stepped into the role of President. In 2025, the company proudly reclaimed its original name—Wendler—in tribute to founder Glenn Wendler’s homegrown vision and legacy of craftsmanship.

Today, that vision has grown to 100+ employees, a substantial fleet, a diversified labor force, a superior management team, and a wealth of industry experience and historical data.

Our Impact

Building Stronger Communities

Our work has always been rooted in service—and that commitment goes beyond the job site. Whether it’s investing in art or future construction leaders, we believe in giving back to the communities that have trusted us for more than 50 years.
