Thamires Monteiro Biography
Thamires Monteiro was born on January 08, 1998, in Vila Mariana, São Paulo, growing up in Mogi das Cruzes, also located in the Brazilian state of São Paulo.
Throughout her childhood, Thamires was not particularly sporty. She did, however, practice dancing and a bit of swimming during her early teenage years, prior to finding her calling in grappling.
Tami’s first steps in jiu-jitsu were made by the end of 2014, at the age of 16. Initially, Monteiro entered the mats solely in a show of support for a good friend who was interested in the Gentle Art but was too shy to try on her own. Although arriving with no long-term goals, Thamires immediately fell in love with jiu-jitsu and decided to join the club.
Monteiro’s time at her original gym was short-lived as she decided to pursue jiu-jitsu as a career during the early stages of her training. Competing nearly every weekend for the first few years, Thamires opted to join the New School Brotherhood team, Leandro Lo‘s (then) newly formed squad, in search of professional training, where Monteiro was promoted to purple belt.
During her travels to the United States, to compete in BJJ’s top tournaments, purple belt Thamires made friends and represented the Atos Team of San Diego, California. Although she built a strong relationship with André and Angelica Galvão‘s workgroup, Thamires would eventually opt to join her husband, Jackson Douglas, at the Checkmat La Habra Academy with coach Lucas Leite. A gym also located in California.
It was while representing Checkmat that Thamires Monteiro was promoted to the brown and black belt ranks by Lucas Leite, the latter promotion taking place in December 2021.
