Stephanie Hym Bell was born on April 16, 1989, in Los Angeles, California. Her father is African American and her mother is Korean. According to Bell, her father was very strict during her childhood due to the sensitive nature of his career. He served in the military before a career as an FBI special agent, working in units for gangs, then missing and exploited children and cyber operations. Bell played volleyball at James Madison High School in the Washington, D.C., suburb of Vienna, Virginia. She then attended Virginia Union University on a volleyball scholarship, where she studied information technology. She played volleyball until her senior year.

A fan of professional wrestling since her childhood, Bell began training at a wrestling school in Manassas, Virginia, at the age of 18, while attending college. She trained for eighteen months before making her debut on August 22, 2009, adopting the ring name Mia Yim, and initially working primarily for independent promotions in Virginia. After taking bookings outside of Virginia, she wrestled for Jersey All Pro Wrestling (JAPW), facing wrestlers including Annie Social, Angeldust, and Brittany Force. During this time, she met Daizee Haze, through whom she began training at the Ring of Honor (ROH) Wrestling Academy and working for ROH. In ROH, she performed valet duties for The Embassy, beginning in 2011. Yim also wrestled sporadically for ROH, taking on MsChif and Sara Del Rey. In addition, she worked for the International Wrestling Cartel, Real Championship Wrestling, Northeast Wrestling, and Maryland Championship Wrestling (MCW) during her early years in wrestling.

After graduating from college, Yim received an invitation to train and wrestle in Japan with Universal Woman's Pro Wrestling Reina in 2011. Through Reina's relationship with Consejo Mundial de Lucha Libre, Yim also learned Mexican lucha libre.

After training with D. J. Hyde at the Combat Zone Wrestling (CZW) training school, Yim began working for CZW as a manager for Adam Cole. Debuting at Cage of Death II in December 2010, the two were presented as a storyline couple, and Yim regularly interfered in Cole's matches to help him win. After helping Cole gain a victory over Greg Excellent at Down With The Sickness 2011 in September, Excellent began feuding with the pair. As part of the storyline, Yim faced Excellent in an intergender match at Night Of Infamy 10: Ultimatum in November. After losing a rematch in January 2012, Yim challenged Excellent to a Tables, Ladders, and Chairs match at Aerial Assault 2012, which Yim won, to conclude the feud. She made only two more appearances for CZW that year before leaving the promotion.

Yim debuted for Shine Wrestling at their second show in August 2012, defeating Sassy Stephie. Throughout 2012 and 2013, she faced wrestlers including Jessicka Havok and Tina San Antonio, before entering the tournament to determine the inaugural Shine Champion. She defeated Mercedes Martinez at Shine 10 in May 2013, and at Shine 11, she defeated Leva Bates and Ivelisse Vélez en route to the final, where she lost to Rain. As part of Shine, she also appeared for Evolve, taking on Vélez and Su Yung in showcase matches.
