[3] Born in San Bernardino, California, Turner attended Summit High School and has described that he grew up in a rough neighbourhood.

In high school he was unable to play much sports such as football, basketball or track and field due to multiple injuries.

[5] Frustrated by the recurring injuries, he started watching MMA bouts on television, which inspired him to try and practice the sport.

[6] With little money as a teenager and unable to afford combat training equipment, he would run and shadow box and used his family couch as a punching bag, until he joined Team Adrenaline which kickstarted his mixed martial arts career.

[8] After compiling an amateur record of 5–2, Turner started his professional MMA career since 2016 and fought primarily in his home state of California.
