Born in Houston, Texas, Olivia Irene "Chachi" Gonzales is the youngest of five siblings. She is of Hispanic descent. At age 6, she enrolled at a dance studio where she trained as a ballet dancer for three years. At age 9, she attended a dance event where she witnessed for the first time a hip hop dance crew. Coincidentally, one of the crews there was Marvelous Motion, whose members (Phillip Chbeeb, Di Zhang and Brandon Harrell) were to become her fellow crew members in I.aM.mE, the dance crew she later joined. She was instantly hooked with this dance style and decided to take up hip hop dancing from then on. She then enrolled in a new middle school where hip hop was one of the styles taught. Very shy at first, months of hard training passed with Gonzales honing and developing her skills, when she was eventually asked by her dance instructor - impressed and with so much confidence in Gonzales - to lead the group she was being taught in. Shortly thereafter, her mother found the Marvelous Motion Studios and enrolled her in a few classes. From then on, Gonzales continued to dance as much as she could, dancing almost everyday, thus becoming a true passion.

In 2010, after the disbandment of Marvelous Motion, the three members Phillip "Pacman" Chbeeb, Di "Moon" Zhang and Brandon "747" Harrell held an audition to create a brand new crew. Added to the lineup were the three new members Olivia "Chachi" Gonzales, Emilio "Millie" Dosal, and Jana "Jaja" Vaňková, forming I.aM.mE, in preparation for America's Best Dance Crew: Season of the Superstars. Gonzales is the youngest member of I.aM.mE.
