Diane and Ken Hendricks started their business journey in the early 1970s in Beloit, Wisconsin. They invested in real estate and owned and operated a growing roofing company. In 1982, they founded American Builders & Contractors Supply Co., Inc. (ABC Supply) by utilizing knowledge gained from their roofing business to respond to a need in the industry. Their guiding principle was to treat contractors with respect and provide them with the products and services they needed to build their businesses.


ABC Supply has revolutionized the roofing material distribution business since its founding. Today, ABC Supply 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, tools, and related supplies.


In 2001, Diane and Ken established Hendricks Holding Company, Inc. HHC is a continuation of Diane and Ken's dreams and a representation of their combined visions. The businesses and associates share a passion for Diane and Ken's values to pursue the American dream. The core values include respect, opportunity, work hard - have fun, entrepreneurial spirit, family, give back, and American pride.


In 2007, Diane lost her husband, Ken, in a tragic accident. Despite this tragedy, Diane has continued to dream big as Chairman of ABC Supply and Hendricks Holding Company, Inc.
