Mackenzie Lynne Dern was born on March 24, 1993, in Phoenix, Arizona, USA.

Both her father and stepmother, Luciana Tavares, were accomplished black belts in the discipline , ensuring a rich training environment from her earliest years. Dern holds dual American and Brazilian citizenship , a reflection of her unique upbringing that saw her splitting time between Arizona and Brazil . This bicultural experience not only deepened her connection to her heritage but also made her fluent in Portuguese , a language that would become integral to her fighting identity.

Dern began her formal Brazilian Jiu-Jitsu training at the remarkable age of three , learning directly from her highly skilled father and stepmother. Her linguistic development paralleled her martial arts journey; she has often spoken about the profound impact of her Portuguese fluency, noting that it became her primary language for fighting, to the extent that she thinks and dreams about martial arts in Portuguese . This early immersion in both the physical and mental aspects of the sport laid a strong foundation for her future career.

Her academic path included attending Ironwood High School in Glendale, Arizona. Displaying extraordinary talent and competitive drive from a young age, Dern entered her first tournament at just six years old . Her precocity was evident as she quickly advanced, and by the age of 14, she was already competing in adult divisions, frequently overcoming older and more experienced opponents . This early dominance on the mats clearly signaled her potential as a formidable grappler.[edit]
