Gail Miller is an American businesswoman, the self-made billionaire owner of the Larry H. Miller Group of Companies (LHM Group), a massive private conglomerate. Her career began with a humble venture: she and her late husband, Larry H. Miller (d. 2009), started their business with a single Toyota dealership in 1979.

Miller's background is one of resilience and hard work; she grew up in a poor family and learned how to create something out of nothing. Her career is defined by her successful transition from automotive retail to sports ownership and large-scale philanthropy, establishing one of the largest private companies in the U.S. West.

Gail Miller's strategic leadership guided the LHM Group through decades of massive growth, expanding from one dealership to more than 60 car dealerships across the West, making it the eighth-largest auto dealer group in America. The company diversified into sports (Utah Jazz), real estate, finance, and entertainment.

The pivotal financial event was the sale of the auto dealer group to Asbury Automotive in 2021 for $3.2 billion, securing immense liquid wealth. Her structural commitment is to her community: she and Larry purchased the Utah Jazz (NBA) in 1986 for $22 million. In 2020, the family sold the Utah Jazz to billionaire Ryan Smith for $1.66 billion, while retaining a small stake and securing the team's long-term commitment to Utah. In April 2025, her family expanded its sports holdings by spending $600 million to buy a majority stake in Utah's two professional soccer teams.

Gail Miller is a major American philanthropist, earning the ATHENA Award and the A Giant in Our City award. The Larry H. & Gail Miller Family Foundation supports a wide range of charitable, educational, and humanitarian causes. Her personal philanthropy focuses on education, healthcare, and homelessness (serving on the Shelter the Homeless Board).

Her structural social impact is tied to the LHM Group's commitment to donating 6 percent of net profit to charity and the massive civic contribution of owning the Utah Jazz, ensuring the team remains a core asset of the Utah community.

Gail Miller maintains the professional, composed style of a successful businesswoman. Her attire is consistently high-quality and elegant, favoring tailored business suits. Her aesthetic is one of stability and profound community leadership, reflecting her humble origins and vast philanthropic commitment.

Residing in Salt Lake City, Utah, her luxury is the immense security and autonomy derived from her multi-billion dollar fortune. Her life is dedicated to the stewardship of her family's legacy, balancing finance, real estate, and her commitment to Utah sports and civic causes.
