Dern was born in Arizona, the daughter of Wellington "Megaton" Dias, a highly decorated grappling competitor himself. Dern began training by the age of three and practicing with her father and stepmother who is also a black belt, Luciana Tavares. Due to her six 1st place finishes at the Asian Open, Mackenzie is the only female Jiu-Jitsu competitor to have won Gold Medals, at Black Belt level, at each of the 5 principal/highest ranking IBJJF Gi Championships - the other events are the Worlds, the Euros, the Pan Ams and the Brazilian Nationals. One of her biggest achievements in BJJ came when she managed to defeat Gabi Garcia despite a huge weight difference, becoming one of the few women to do so.
