Diane Marie Hendricks stands as one of the most powerful and influential business leaders in the United States. Known widely as the co-founder and chairperson of ABC Supply, she has built a remarkable legacy in the building materials industry—an arena historically dominated by men. Her journey from a rural upbringing to becoming one of America’s richest self-made women is a compelling story of resilience, ambition, and strategic thinking.
Beyond business, Hendricks is also recognized for her involvement in economic development, political contributions, and philanthropy. Her life reflects the classic entrepreneurial narrative: starting small, embracing risk, and scaling a business empire through vision and persistence.
Early Life and Background
Diane Hendricks was born on March 2, 1947, in Osseo, a small town in rural Wisconsin. She grew up on a dairy farm, which played a significant role in shaping her work ethic. Life on the farm was demanding, requiring discipline, long hours, and a strong sense of responsibility—qualities that would later define her business career.
Raised in a hardworking, modest family, Diane learned early the value of perseverance. Her childhood was not marked by privilege but by effort and determination. She attended local schools in Wisconsin and later pursued further education, although her path was far from traditional. Instead of following a conventional academic route, she gravitated toward hands-on work and practical experience.
Before entering the business world, Hendricks worked as a model in her younger years. While this may seem like an unusual starting point for a future industrial leader, it exposed her to broader opportunities and environments beyond her rural upbringing. However, her true calling lay in entrepreneurship and construction.
Entry into the Construction Industry
Diane’s transition into the construction and roofing supply industry began through her association with her husband, Ken Hendricks. Ken was already deeply involved in roofing and construction, and together they formed a powerful partnership—both personally and professionally.
In 1982, Diane and Ken co-founded ABC Supply. The company began as a small distributor of roofing materials, operating with a simple yet effective business model: provide high-quality products, maintain strong relationships with contractors, and deliver exceptional customer service.
At the time, the building supply industry was fragmented, and few companies focused on customer-centric service. Diane and Ken recognized this gap and capitalized on it. Their approach emphasized reliability, trust, and efficiency—qualities that quickly set ABC Supply apart from competitors.
Building ABC Supply into an Empire
From its humble beginnings, ABC Supply grew rapidly under Diane Hendricks’ leadership. The company expanded across the United States, opening branches in multiple states and becoming one of the largest wholesale distributors of roofing, siding, and windows.
After the sudden passing of Ken Hendricks in 2007, Diane assumed full leadership of the company. This moment marked a defining chapter in her life. Rather than slowing down, she accelerated the company’s growth trajectory.
Under her guidance, ABC Supply achieved several milestones:
- Expansion to over 800 locations across the United States
- Acquisition of major competitors, including Bradco Supply
- Strengthening its position as the largest wholesale distributor of roofing materials in America
Diane’s leadership style is often described as decisive and forward-thinking. She has consistently focused on long-term growth rather than short-term gains, reinvesting profits into expansion and innovation.
Her ability to navigate economic downturns—particularly in the construction sector—demonstrates her strategic acumen. While many companies struggled during housing market fluctuations, ABC Supply maintained stability and continued to grow.
