Professor Aparecido Bill grew up in Rio de Janeiro and started jiu-jitsu at 7, with Grandmaster Monir Salomão. He earned his black belt from Professor Wendell Alexander, competed at the national and world level and moved to the United States in 1996 to share what the mats gave him.

I can’t praise Bill BJJ enough. From the moment I walked in, I felt welcomed and included by both the instructors and students. The atmosphere is genuinely friendly and supportive, and the adult class accommodates all skill levels, allowing everyone to progress at their own pace. Professor Bill is highly skilled and knowledgeable, balancing technical details with big-picture concepts. His dedication to his students’ growth, on and off the mat, is clear in everything he does. If you’re serious about self-defense and personal growth, this is the place to be. Highly recommended!
Reese EdwardsAdult student
I’m so happy to have found Bill Brazilian Jiu-Jitsu. The professors and coaches are amazing with my kids, and the level of instruction is world class. Professor Bill and his team treat everyone like family and are always willing to take the time to speak with parents. I highly highly recommend this organization for anyone interested in learning Jiu Jitsu themselves or for their children.
