Mace Coronel became famous during his childhood years for his role as Dicky Harper in the Nickelodeon comedy series Nicky, Ricky, Dicky and Dawn. He began his acting career when he was just seven years old and was quickly cast in episodes of Days of Our Lives and Hart of Dixie. He played the recurring role of R.J. Forrester on the CBS soap opera The Bold and the Beautiful.

Mace began taking acting classes when he was 7 years old. He soon quit the classes as he felt he wanted to become a stand-up comedian rather than an actor because it was his dream to stand on a stage and make people laugh. In 2011, Coronel appeared in a couple of television commercials. His first was for Samsung, but it was only aired in South Korea. He also did a couple of short student films at the time.
