S tuart Miller is an American billionaire and the executive chairman of the board of Lennar Corporation, one of the largest and most successful homebuilders in the United States. He represents the second generation of his family's business, which was co-founded by his late father, Leonard Miller, in 1954. Stuart has been the driving force behind the company's massive growth and its transformation into a national powerhouse.

He has served as the company's longtime CEO for many years before transitioning to the executive chairman role. He has a reputation as a shrewd and often contrarian dealmaker, having successfully guided the company through numerous housing cycles and having grown the business through a series of major acquisitions of other homebuilders. His family's vast fortune is derived from their large controlling stake in the publicly traded company his father co-founded and which he has built into an industry giant.
