Our History

In 1973, WRH, Inc. was founded as Wendler Engineering and Construction, by Glenn Wendler. The civil focused construction company was small but mighty, the company generated staying power as they 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 had earned a well-known and well-respected reputation. In 2020, WRH, Inc. appointed Randy Reihmann as Chairman of the Board, and Jamie Rich took his place as President. Currently, WRH, Inc. has 100+ employees, a substantial and differentiated construction equipment fleet, a diversified labor force, a superior management team, and a wealth of industry experience and historical data.
