Miller won a silver medal at the
2012 AIBA Women's World Boxing Championships in
Qinhuangdao, China. She recorded victories over Daena Stephenson of New Zealand, Canada's Myriam Da Silva, Turkish boxer Bilgehan Karabulut and Irina Poteyeva from Russia before losing to Ukraine's Maria Badulina in the final. She made her professional debut on May 21, 2016, scoring a first-round technical knockout over Sara Flores at the Richmond Memorial Auditorium in
Richmond, California. Miller won the vacant
NABF female
middleweight title on 18 May 2019, stopping
Erin Toughill in the seventh-round at
Gardens Casino,
Hawaiian Gardens, California. Toughill was knocked to the canvas after just 15 seconds of the opening round but recovered to battle on until round seven when she was dropped again and, despite beating the count, referee Zachary Young waved the fight off. In November 2025, Miller signed with Most Valuable Promotions. ==Professional boxing record==
