Before she became a NASCAR driver, she served as a middle school principal in Slidell, Louisiana, resigning in December 2004 to focus full-time on her racing career.
Crosby originally was a drag racer, competing in the NHRA and IHRA for fifteen years.
She began oval racing in 2000 at the Buck Baker Driving School, where she graduated in the advanced class.
She ended up making her Busch Series debut at Talladega Superspeedway, finishing 20th in the #51 Boudreaux's Butt Paste Dodge owned by Ware Racing Enterprises.
By mid-season, she left GIC and signed to drive the #26 Chevrolet for Keith Coleman Racing, finishing 28th at Daytona International Speedway.
In 2006, it was announced she would run a part-time schedule for Frank Cicci Racing with Jim Kelly.
She continues to pursue sponsorship for her own Monster Jam theme truck and plans to reenter the NASCAR ranks if the right opportunity arises.
