Jeferson Guaresi Biography

Jeferson Guaresi was born on June 01, 1998, in Rolim de Moura a city located on the Brazilian state of Rondonia, in the northern region of the vast South American country.

Prior to jiu-jitsu, during his childhood, Jeferson played football (soccer) at a state level, in the goalkeeper’s role. Although short for the position, Guaresi’s athleticism and hard working ethics helped him and the team conquer many regional tournaments.

As an 11-year-old Jeferson added jiu-jitsu to his daily sporting routine, influenced by a few close friends who already grappled in Rafael Godoi’s gym, a man who would also be Guaresi’s first instructor and the man who incentivized Jeferson towards competition, believing in the youngster’s full potential.

With time the relationship between Godoi and Guaresi grew, and coach Rafael established himself as a fundamental piece in Jeferson’s upbringing. In 2015, after a lesser performance at the Brazilian Nationals (CBJJ), Rafael pressed on Jeferson to make a decision on whether to take his career to a professional level or take a different path in his life. Fully embedded in grappling culture already, Guaresi chose jiu-jitsu. Believing in Jeferson’s desire to take it to the “next level”, Godoi then introduced Guaresi to Cicero Costha, one of the best jiu-jitsu instructors in Brazil, who lead the biggest jiu-jitsu talent factory in the world at that time. After this initial introduction, Jeferson moved to São Paulo (2015) to train full-time at Cicero’s famous camp, PSLPB, staying there for 2 years.

Jeferson earned his brown belt at the hands of Cicero Costha, after which he started visiting the Unity Academy in New York City, a gym with a strong connection to Cicero Costha, sharing several athletes between the two training camps. This Cicero Costha / Unity coalition would unite to award Jeferson Guaresi his black belt in mid-2019.
