Message from the President and CEO - Brian Miller
At Wausau Supply Company, our mission has always been to serve our customers with unmatched quality, innovation, and partnership. It’s a mission I’m proud to carry forward as President and CEO.
Having been part of the Wausau Supply team for almost a decade, I’ve had the opportunity to work alongside incredible people and grow within a company deeply rooted in its values. As a 100% employee-owned business, we operate with a strong sense of responsibility—to each other, our customers, and the communities we serve.
Our future is filled with momentum. From the acquisition of ChamClad to the opening of new distribution centers across the country, we are investing in capabilities that will help you grow—whether through premium brands.
Our Core Values Guide Everything We do
At Wausau Supply Co., our core values are more than just words; they are the foundations on which our company is built. Our daily commitment to these values is what sets us apart from the rest.
Safety - We believe that all injuries are preventable and that by working together we can make safety a way of life, inside and outside the workplace.
Service - We will meet every customer expectation with the highest level of service and quality.
Innovation - We encourage our employees to create ethical, forward thinking solutions to problems identified.
Integrity - Expect the highest standards of ethical conduct and a commitment to open and honest communication.


Proud to be 100% Employee-Owned
In 2001, through an Employee Stock Ownership Plan (ESOP), Wausau Supply Co. sold the company to its employees and, in 2015, became 100% employee-owned.
What does that mean? It means that our employee-owners are all in this together and everyone’s contributions matter. They are accountable to themselves, each other and our customers. It also means that they share the benefits of our collective success through shares of company stock.
Our employees take pride in their efforts each day knowing their decisions impact the success of their company.
