About Quam

The Quam Construction story started in 1956 with John Quam and his wife Irene. The vision for their company consisted of a simple yet powerful work philosophy: “Work hard. Do it right. And treat people with respect.” The married couple managed their first construction project in Storm Lake, Iowa, and then another in Cherokee, Iowa. From there, the Quams hitched up their mobile home and moved northward from job to job, residing temporarily wherever they found projects. Because of their diligent dedication to quality work and the trustworthy relationships John and Irene built with their clients, business became more and more steady. Finally, in the early 60s, their journey led them to Willmar, Minnesota, where they decided to put down roots and manage their growing business. John and Irene had four children, two sons – David and Terry, joined them in the business.

Over the past 60 years, Quam Construction has become a quiet leader in the construction industry. As a family-owned company with humble beginnings, Quam Construction has flourished, today completing projects throughout the upper Midwest, including Minnesota, North Dakota, South Dakota, and Iowa. The quality of our finished projects combined with enduring values instilled by John and Irene Quam decades ago have resulted in a solid reputation for Quam Construction that we continue to uphold.

Today, Quam has expanded from the original construction focus to include trenchless technology applications that allow our company to be an end-to-end underground infrastructure solutions company. Quam strives to employ experienced industry professionals and expects all employees to positively represent the Quam name when on the job and to uphold our strict standards for safety and compliance. We will always strive to maintain client relationships on the same personal level as the company founders did in the beginning. This allows us to routinely handle projects of all sizes and scopes, without compromising quality. Quam is proud to offer great career opportunities for those who seek personal growth and enjoy a challenge.

As a family-owned company with humble beginnings, John Quam’s work philosophy is still in place today “work hard, do it right and treat people with respect”.
