In 2008, Diego began his training under Luciano Nucci “Casquinha”, founder of the gym “Alliance Mooca” and accomplished black belt under Ryan Gracie. It was at this time that he dedicated himself fully to the BJJ lifestyle.
Since then, Diego has stuck with his lineage and roots, competing and medaling in the South American Championships, winning international competitions such as American Nationals Championship, Pan American Championships, and many national International Opens through the International Brazilian Jiu-Jitsu Federation (IBJJF).
In 2019, Diego received his black belt from Casquinha and has since won gold at all IBJJF Championships in the state of Texas, a winning streak in which he has dubbed “Texas Golden”, and has competed in televised and streamed events like KASAI Grappling (1-1) and Fight 2 Win (4-2), both in Gi and No-Gi.
Diego holds a Bachelor’s Degree in Public Administration from the University of São Paulo, one of the most accredited universities in South America. On the weekends, you’ll find him exercising outdoors or barbecuing with friends and family.
He is a dog lover and also a proud father to his son Leo. While we have different programs and coaches at Underground Jiu-Jitsu, Diego is our head coach and builds all of our curriculums.
Prior to that, Sydney had done a bit of ballet, a bit of figure skating, piano, violin, and whatever else parents usually sign their kids up for. In 2016, she started Cross-Fit but didn’t really get into fitness until that first Jiu-Jitsu class.
Today, she holds the rank of brown belt in Jiu-Jitsu after 7 years of training and competing. Jiu Jitsu transformed her life into one that revolves around fitness, strength and conditioning, and healthy habits. She competes regularly in local Jiu-Jitsu competitions and trains alongside her husband, Diego. She is currently the coach for the Women’s Only classes offered at Underground Jiu-Jitsu and focuses on building a safe training environment for women to learn self-defense, fitness, and community-building.
Her achievements as an athlete:
– IBJJF 2024 American National Champion – Purple Belt
– IBJJF 2024 Dallas Open Champion – Purple Belt
– IBJJF 2024 Houston Open Champion – Purple Belt
– 2x Jiu Jitsu World League Dallas Edition Champion – Purple Belt
Sydney received her Undergraduate Degree in Business Administration and Marketing from the University of Texas at Dallas (UTD), and works as a Budget Analyst in local government.
She is also the proud mother to her and Diego’s baby boy, Leo.
I received my Blue Belt under Coach Diego in 2019, but unfortunately life got in the way, and needed to take a step back from training for personal reasons. Fast forward to 2022, Coach Diego reached out to invite me to his new school, Underground Jiu-Jitsu, and I am forever thankful he did.
I was promoted and received my Purple Belt under Coach Diego, and I have taken the amazing opportunity to be the primary coach for the Little Warriors class (6-9 years old); these kids have literally ‘rolled’ themselves into my heart.
