Teresa Earnhardt net worth: Teresa Earnhardt is a North Carolina born businesswoman and NASCAR team owner with a net worth of $50 million dollars. Born in Hickory, North Carolina, Teresa Earnhardt holds degrees in commercial art and interior design. She met racecar driver, Dale Earnhardt, Sr. in the late 70s, and they married in 1982. She served as the head of Dale Earnhardt, Incorporated, for both Busch Series Championships and Craftsman Truck Series Championships in the late 80s. She also headed the team again in 2004 and 2005. Tragically, her first Daytona win as a NASCAR owner, was the same race in which her husband was killed during the final lap. Multiple sponsors withdrew their funding after the death of her husband, and she subsequently merged Dale Earnhardt, Incorporated with Chip Ganassi Racing, to form Earnhardt Ganassi Racing. The new team won its first Daytona in 2010, with driver, Jamie McMurray at the wheel.
