Charlie-ChubFounded in 1960 by “Charlie” Cummins and “Chub” Wagner, Cummins-Wagner began as a one-product, two employee company in a one-room office.

Without a well recognized major brand product line, their commitment to customer service was the company’s sole strength. This commitment to customer service, allowed the company to grow and attract major product lines. Recognizing that the ownership had bred the dedication that resulted in the success of their customer-driven business, they established an ESOP and sold the company to the employees in 1985.

Today, the company’s strength comes from both the superb product lines that are distributed and the total dedication of its nearly 200 Employee Owners to the principle of customer satisfaction.

As an “ESOP” company with 100% of the common stock universally and exclusively owned by the Employee Stock Ownership Trust (ESOT), employees are motivated to work for the long-term success of the company to a degree unmatched by those of our competitors. ESOP companies generally outperform non-ESOP companies. (For more information on ESOPs, visit www.esopassociation.org)

We view our vendors as partners, and our commitment to each is without reservation. Together we must formulate strategic plans that will enable us not only to realize short-term sales objectives, but those that will allow us to lead, and if possible, dominate our market.

The company continually invests not only in physical assets, …. inventory, tools, and facilities, but also in the latest communication and computer technology for the rapid collection, analysis, and transmission of data. We believe that time is of the essence in every facet of our business, and that the rapid exchange of information is vital to our success, whether such information is for the benefit of our customers, our sales force, or our trading partners. We strive to be on the cutting edge in the application of technology and equipment that will allow us to better serve both our upstream and downstream trading partners.

The company’s employee compensation package is second to none in the industry, consistent with the belief that our employees represent our most important asset. We are able to attract, hire, train and retain top-notch people by meeting both short and long-term needs of our Employee Owners. The Company is an Equal Opportunity Employer.
