E ren Ozmen is a Turkish-American self-made billionaire businesswoman who is the chairwoman, president, and majority owner of Sierra Nevada Corporation (SNC), a major American aerospace and defense contractor. Her story is a remarkable example of the American dream. She came to the United States from Turkey in the early 1980s to pursue her MBA, sometimes selling baklava to make ends meet.

She joined the small technology company SNC in the 1980s. In 1994, she and her husband, Fatih Ozmen, who also worked at the company, mortgaged their house to acquire SNC. Together, they have built the company from a small firm with about 20 employees into a multi-billion dollar global powerhouse. As the strategic leader of the company, Eren has overseen dozens of acquisitions and has expanded SNC's capabilities into a wide range of areas, from surveillance systems and cybersecurity to commercial space travel with its innovative Dream Chaser spaceplane. She is one of America's wealthiest self-made women.
