Rothwell is from Kenosha, Wisconsin, and both of his parents work in the restaurant business. His parents own a catering company. He is of Norwegian and Irish descent.[3] Rothwell was an active child but suffered a bout with spinal meningitis when he was six years old. He was in a coma and temporarily blind, while the disease made him almost obese. The young Rothwell, who struggled with his weight and identity in his adolescent years, was also troubled growing up and was often involved in fighting and violence at Westosha Central High School. By the time he was a junior in high school, Rothwell knew that he enjoyed fighting, and in 1999, at the age of 17, he began learning self-defense. In July of that same year, after he had been in three professional fights, he and a friend were involved in a car accident with a drunk driver. Rothwell's friend, who was 19 years old, died two weeks later, and Rothwell suffered a significant head injury, in addition to broken ribs. The event changed Rothwell's life, causing him to feel as though he has a purpose to complete.[4]
