About Us

Kolbe and Kolbe history wash house

Message from the CEO

In 1946 two brothers, my father Herb Kolbe and his brother Ervin, began a business repairing and building windows and door frames. Their little shop was located in a wash house (left) on an 80-acre family dairy farm in Marathon, Wisconsin.

Since those days over 70 years ago, Kolbe & Kolbe has grown into a nationally recognized leader in the premium window and door industry, selling its broad range of product offerings through hundreds of distributors and dealers across the United States, Canada and beyond.

While my father and uncle are no longer with us, their spirits live on in our company today. As Chief Executive Officer, I am committed to continuing Kolbe & Kolbe as a closely-held, family business. We will not depart from the philosophies that made our company successful. We will continue our commitment to our employees and we understand the very important role that Kolbe & Kolbe plays as a major employer in Wausau and the surrounding communities. Our commitment will not be deterred by the vagaries of the national or local economy. Kolbe & Kolbe Millwork Corporate LogoWe will remain true to our principle that was best stated by my father when he said, "our success is due to the people, the many employees who have served loyally over the years. They are, in essence, an extension of the Kolbe family."


Message from the President

Jeff De Lonay, President

Over thirty years ago, I joined this organization as a general laborer because I loved working with wood. I was placed in a production area responsible for making double hung windows. Being a quick study, I was able to learn the parts and processes well enough to be cross-trained in a number of other production areas. Through hands-on training, I began to fully understand the products and their construction. I also recognized that it was the people who really instilled in the products the lasting quality, which, in essence, is the heart and soul of the organization.

I am thankful to be a part of such a dynamic organization that continues to use the principles on which it was built to mould its future and continue the successes of its founders. As Herb Kolbe said, "We don’t strive to be the biggest, but we do strive to be the best."  This is, and continues to be, our commitment to our team members, business partners and the customers we serve.
