Diane M. Hendricks is an American billionaire businesswoman, entrepreneur, and philanthropist best known as the co‑founder and Chairwoman of ABC Supply Co., Inc., the largest wholesale distributor of roofing materials and other exterior/interior building products in North America. She helped launch the company in 1982 with her late husband, Kenneth Hendricks, turning three failing supply centers into a nationwide enterprise with more than 900 locations across the United States and Canada and multibillion‑dollar revenues.
Hendricks also leads Hendricks Holding Co., Inc., a diversified private holding company with interests in manufacturing, real estate development, construction, recycling, and life sciences. Since 2007, following the untimely death of her husband, she has served as Chairman and sole owner of ABC Supply, guiding its strategic growth while championing a company culture focused on respect for associates and service to professional contractors.
Born in Mondovi, Wisconsin, and raised on a dairy farm, Hendricks worked her way into business at a young age, earning a real estate broker’s license in her early 20s before entering custom home sales and later partnering with Ken Hendricks in real estate investing and supply distribution. Her leadership and business acumen have made her one of America’s most successful self‑made entrepreneurs, with Forbes repeatedly recognizing her among the richest self‑made women in the United States.
In addition to her corporate work, Hendricks is active in civic and philanthropic efforts, emphasizing local community development, veteran support organizations, and economic revitalization projects centered in Beloit, Wisconsin — where ABC Supply and Hendricks Holding are headquartered.
Known for her patriotic and conservative values, she remains a prominent figure in business and public life, balancing corporate leadership with contributions to the community and national causes.
