In 1975, Diane met Ken Hendricks, a high school dropout and roofer.

Following Ken's untimely death in 2007, Diane assumed full leadership of the company, steering it toward continued growth and expansion.

How did Diane Hendricks make money?
Diane Hendricks built her fortune by co-founding ABC Supply in 1982 with her late husband, Ken Hendricks. They identified a gap in the market for a national distributor of roofing and building materials, focusing on providing contractors with fast, reliable service. The couple started the business in Beloit, Wisconsin, using their savings and credit lines to fund the venture.

ABC Supply’s early success was driven by strategic acquisitions of smaller, regional distributors. Over time, the company expanded its offerings beyond roofing to include siding, windows, and other building materials. Hendricks' focus on customer service and maintaining strong relationships with contractors helped ABC Supply become the largest wholesale distributor of roofing materials in the United States.

After Ken’s untimely death in 2007, Diane took full control of the company. Under her leadership, ABC Supply continued to grow, reaching over $15 billion in annual sales by 2023. The company's acquisition of Bradco Supply in 2010 and L&W Supply in 2016 significantly boosted its market share.

In addition to her building supply business, Hendricks has invested heavily in real estate and community revitalization projects in Beloit, Wisconsin. Her Rock County Development initiative has transformed the local economy, creating jobs and revitalizing the downtown area.
