A Quiet Force in the Costner Family
Daniel Craig Costner was born into a family of strong values, hard work, and creativity. As the eldest of the three Costner brothers — Daniel, Kevin, and Mark — Daniel naturally carried the responsibility and leadership role that comes with being the firstborn. He was raised in California by their father, William Costner, an electrician for Southern California Edison, and their mother, Sharon Costner, who was a welfare worker. The Costner household emphasized discipline, integrity, and education, values that deeply shaped Daniel’s trajectory in life.
Unlike Kevin, who pursued acting and later achieved worldwide fame, Daniel Craig Costner chose a path outside the public eye, aligning more with traditional business ventures and entrepreneurial endeavors. His story is a testament to the fact that not all great successes need to be center stage.

Much of his early career was spent in environmental and technical roles. He worked in the oil industry and has contributed to several business ventures that bridge the gap between environmental technology and practical industrial applications.

In fact, he was connected to a company called Ocean Therapy Solutions, a venture closely associated with Kevin Costner as well.
Ocean Therapy Solutions made headlines during the 2010 Deepwater Horizon oil spill disaster in the Gulf of Mexico. Daniel and Kevin worked together to promote a technology that could separate oil from water — a potential game-changer for oil spill cleanup operations. Daniel, with his business acumen and technical insight, played a crucial role in the operational and strategic side of the venture. This example not only demonstrates Daniel’s commitment to environmental responsibility but also highlights his close working relationship with Kevin, albeit far from the red carpet.
