Ken and Diane Hendricks of Hendricks Holding Company

Diane and Ken started out by investing in real estate in the Beloit College area. After several years, and approximately 100 home renovations, they founded ABC Supply Co., Inc. in 1982.

By 1982, they were already successful entrepreneurs and owned two well-established companies-International Roofing and Hendricks Real Estate Properties. During the economic slowdown of 1982, Diane and Ken decided not to sit back and wait for better times to come. Instead, they chose to take a risk and acquire three supply centers from Bird & Sons Inc. These centers were the first locations of the new American Builders and Contractors Supply.

Diane and Ken's dream was to put their contractor customers' needs before everything else, treating them like the professionals they are, giving them the tools they deserve and upgrading their image along the way. They believed there was a better approach to meeting contractors' needs, and that philosophy is the cornerstone of the dream that is today's ABC Supply.

Since its founding, ABC Supply Co. Inc. has revolutionized the roofing material distribution business. In the process, the company has grown into a $10.5 billion enterprise serving the needs of the professional contractor with exterior building material stores across the United States.

The success that is chronicled in the history of ABC Supply is the result of an unwavering focus on a single, simple guiding principle-treat contractors with respect, and give them the products and services they need to build their businesses.

Today, ABC Supply company has more than 750 locations nationwide, with over 15,000 associates, and is the largest wholesale distributor of roofing products in the United States, and one of the largest distributors of siding, windows and other select exterior and interior building products.

ABC Supply remains an "employee-first" company that treats its associates with respect and gives them the tools they need to succeed. It is a 13-time winner of the Gallup Great Workplace Award, which recognizes the best-performing workforces in the world, and recipient of Glassdoor's Employees' Choice Award, which recognizes the best places to work in the U.S.

HHC formed in 2001, and represents a continuation of Diane and Ken's dream. The businesses and associates all share a common passion for the principles that Diane and Ken followed, and continue to follow, in pursuit of the American dream: respect, opportunity, hard-work, entrepreneurial spirit, commitment to family, giving back to the community and pride in the greatest country in human history - the United States of America.

Hendricks Holding Company is comprised of committed, talented, and thoughtful people who aspire to improve our companies’ performance as well as the communities within which we work and live.  Our most important assets are our people, capital, and reputation.  We are committed to a culture of integrity, entrepreneurship, and achievement.
