The Boldt Company

Since 1889, we’ve stayed true to what Martin Boldt first set out to be—an honest and reliable contractor. Hard work, an innovative spirit and a commitment to our values have helped us grow into one of the largest professional construction services firms in the United States. Today, we’re a fourth-generation family- and employee-owned company with a home base in Appleton, Wisconsin and offices throughout the country.

We’re proud of how far we’ve come. But we’re not in this business for ourselves. We’re in it for everyone who benefits from what we do—to deliver as much value as possible to our customers, their customers and the communities we help to build.
