Advantages of Keller


Every Keller-built structure comes with a guarantee of materials and craftsmanship for a specified period of time following completion. But that doesn’t mean we wash our hands of responsibility if something were to occur after the guarantee period. That’s not good for the customer and it isn’t good for our business. Keller believes that standing behind the final product means working with the customer to resolve the issue to everyone’s satisfaction.


With any construction firm, the benchmark of success has to be its level of customer satisfaction. And we’ve found that a great deal of that satisfaction starts with involving the customer throughout the project. So from the earliest stages through completion, we’ll keep you updated on your building’s progress, fully explaining each step, answering all of your questions, offering clear, understandable options and making sure your project stays on time and in budget.


Keller is 100% employee-owned. That means that every employee that works on your project is an owner of the company, from your Project Manager and Architect to your Estimator and Foreman, you are always working with an owner. That means your questions are answered faster, your jobsite is kept cleaner, and your work is completed with more pride when you work with Keller.


When business growth plans hinge upon the completion of your facility, time is of the essence. The coordination inherent in the Design/Build teams employed by Keller allow us to move ahead quickly, often able to take such time-saving methods as pouring concrete and placing footings well before floor plans have been finalized and approved.


Complete the project as though you were building it for yourself.

–Walter Keller

Keller, Inc., was founded in 1960 by veteran builder Walter Keller in Kaukauna, Wisconsin. Originally focused almost exclusively on large-scale agricultural structures, Walter was instrumental in expanding his company’s presence into other industries, including retail, financial and healthcare.

Walter oversaw the company’s conversion from a family-owned business to an employee-owned enterprise, through an ESOP (Employee Stock Ownership Plan) in 1986. Though Walter retired as Keller’s President in 1989, his original values of integrity, honesty and commitment to putting the customer first still inspires today’s highly dedicated professional and field staff. Keller now has offices in the Fox Cities, Madison, Milwaukee and Wausau and the company has grown to more than 250 employee-owners.
