Wheeler was born to Barry, a longtime project coordinator for Georgia Power, and Elaine Wheeler in Smyrna, Georgia. Wheeler has two older brothers, Jacob and Adam. The Wheeler family was gifted athletically. Adam was selected by the New York Yankees in the 13th round of the 2001 Major League Baseball Draft and pitched in their farm system for four years before his career was derailed by injury. Barry also played in a men's baseball league, while Elaine lettered in varsity basketball and softball during all four years of high school and continued to play softball competitively as an adult. Wheeler's brothers are both nearly ten years older than he is and pushed him to excel in sports from a young age; at the age of two years, his brothers taught him to dribble a basketball, throw a baseball and switch-hit.
