Keller Inc

Company Overview


Keller Inc. is a premier Design/Build General Contractor in Wisconsin, providing top-notch services since 1960. With headquarters in Kaukauna and offices in Madison, Milwaukee, and Wausau, our company has grown to become the go-to contractor for construction projects across the state. We pride ourselves on our team of approximately 260 skilled and dedicated employees who work tirelessly to deliver exceptional projects for our clients.

Founded by Walter Keller, our company has a rich history and a strong foundation. In 1989, Walter was named Chairman of the Board, and since then, our current officers - Cory VandeWettering as President, Steve Klessig as Vice President of Architecture and Engineering, Craig Otis as Senior Vice President of Construction, and Douglas Stecker, CPA as Vice President of Finance/CFO - have continued to lead our company towards success.

At Keller Inc., we believe in the power of employee ownership. In 1986, we established an Employee Stock Ownership Plan (ESOP), making our company 100% owned by our employees. This unique concept not only fosters a sense of ownership and responsibility among our team members, but also results in a higher level of professionalism and quality in our projects.

We have a diverse portfolio, having served clients in various industries such as agriculture, automotive, senior living, education, healthcare, hospitality, and more. Our expertise in construction management, municipal projects, and design/build services has earned us a reputation as a reliable and efficient contractor.

At Keller Inc., we are committed to delivering exceptional results for our clients. Our experienced team, combined with our dedication to quality and innovation, sets us apart from our competitors. We are proud to be a part of the Wisconsin community and look forward to continuing to serve our clients with the highest level of professionalism and excellence.
