Maycee Kaye Barber was born in Greeley in Colorado. At a young age, she started training in MMA with the goal of becoming a professional competitor.
Barber and her sister ran a BJJ academy in Fort Collins after going through the highly suspect Gracie University program.
The two were blue belts at the time and just 16 years old and there was quite a bit of backlash from the community.
Much of the backlash focused on the fact that there was a picture in which Barber wore a black belt – which she obviously didn’t receive.
Barber pivoted to MMA quickly after that.
Barber’s father Bucky Barber explained the situation to Yahoo Sports’ Kevin Iole in an interview. He said: “At that point, it was, ‘OK, the better we make her as a fighter, the less damage she’s going to take.’ So we started to travel, and we took her literally all over the United States.”
Barber also has a younger brother named Wyatt. He is a Bellator-affiliated mixed martial artist.
In June 2017 at LFA 14, Barber faced Itzel Esquivel in her first career match. Her armbar submission in the first round gave her the victory.
