EARLY LIFE AND EDUCATION
Donald Leroy Bren was born on May 11, 1932 in Los Angeles, California. As a young boy, Bren experienced the difficulties in life that many Americans faced as a result of the great depression, and the isolation of the great depression era. His father was employed in the real estate industry and had a profound influence on Bren and his later career in real estate.
Since childhood, Bren was always curious about architecture, development, and business. He was curious about how towns and communities were designed, and how land could be turned into successful neighborhoods. Soon, his curiosity grew into a passion for real estate development.

Prior to his career in the business world, Bren A set out on a different path and served in the armed forces of the United States. His Marine Corps experience provided the foundation of tools in which he needed to succeed, including leadership, discipline, and determination.

CAREER JOURNEY
In the 1950s Donald Bren first established himself as a budding developer on the lookout for opportunities in real estate development. In the face of Southern California where population boomed, Bren sought and found enormous potential in deals relating to the construction of residential dwellings. In this venture, he focused on the development, assembly and sale of homes.
His first notable achievement was the creation of the Bren Company. This company specialised in creating residential developments throughout California and soon gained a good reputation for not only building spectacular architecture but for planning them well and for doing so efficiently. His business grew as the need for new houses grew so increased his projects.
But then, in the 1970s, Bren took control of the Irvine Company. The company had what would turn out to be substantial holdings in Orange County, California, and an astute Bren saw an ideal play-one that few others even understood. Instead of aggressively flipping land at high profit margins, he chose:
Under his management, the Irvine Company became a major force in real estate. They built neighborhoods, offices, retail centers, apartments, hotels, golf courses, and more. The variety of projects provided the company with several different sources of income and growing land holdings.
