ABC Supply co-founder Diane Hendricks is the richest self-made woman in America
Diane Hendricks, co-founder of the Beloit-based ABC Supply roofing and building supplies company, topped Forbes' list for the sixth year in a row, with an estimated net worth of $15 billion as of June 2023. Forbes also estimates that Hendricks is the 109th-richest billionaire in the world.
