Greyson is in the fifth grade at Oak Grove Intermediate School, Darien, GA, where his mother, Dana, is also a teacher. His father, Brian, owns Island Rental on St. Simon Island. 
He later moved from open wheel modified to a sprint car, best described as a “wing on top,” which he drove for three years. He decided to return to Go Karts, partially because of expense, when Callahan Speedway opened.
