MEET Leigh Macneil
Head Instructor at Carlos Machado Jiu Jitsu Denton
At the heart of Carlos Machado Jiu Jitsu Denton is Leigh Macneil, who fills the roles of owner, operator, and head instructor with unmatched passion. Beginning his martial arts journey in the Northeast with Judo and Wrestling, Leigh expanded his expertise to Boxing, Kickboxing, Muay Thai, and was an early adopter of Mixed Martial Arts. Relocating to Texas in 2014, he embraced Brazilian Jiu Jitsu wholeheartedly. A family man at his core, Leigh’s commitment to fostering a supportive environment is evident in every aspect of the academy. His deep connection with mentor and friend Carlos Machado shapes his teaching, making him an invaluable guide for both newcomers and seasoned practitioners alike.
Renee Macneil
Owner/Operator
Renee, a native Vermonter, holds a Master’s in English from the University of Vermont. Formerly a high school English teacher for thirteen years, she and Leigh moved to Lantana, Texas in 2015. In Texas, they co-authored two books and Renee began a new career at a medical spa. Inspired by a thriving small business, Renee joined Leigh in his goal of opening a Brazilian Jiu Jitsu school. She mostly handles back and front-of-the-house work for CMJJ Denton. A family-owned venture, Renee is proud of Leigh’s dedication to their business and family. When not at the academy, Renee raises their two daughters who attend Denton ISD schools and trains for races and marathons.
