Ground Zero BJJ Bridgeport

Ground Zero BJJ Bridgeport is led by Jeb Tonkin, a black belt under Phil Davis and Don Cunanan who has cultivated nearly a decade of teaching experience alongside a solid competition record. The academy traces its lineage through Mitsuyo Maeda, Carlos and Helio Gracie, then through Joe Moreira and Randy Bloom, connecting to Tonkin’s instructors. Tonkin’s background in law enforcement and defensive tactics shapes a teaching approach focused on developing skilled grapplers and disciplined individuals. The gym also features a team of black and brown belt instructors, including Don Quinn, the first black belt promoted at the Bridgeport location, and Zack Humbertson, a seasoned competitor with extensive tournament experience. Training at Ground Zero is structured around a curriculum that serves both youth and adult students. The youth program, headed by brown belt Andy Isner, emphasizes discipline and character development alongside technical progression, offering classes for children aged 6 to 12. Adult classes welcome practitioners of all belt levels, focusing on gi training with a curriculum that balances fundamentals and advanced techniques. No-gi is not mentioned as a primary focus, maintaining the traditional gi-centered approach consistent with the academy’s roots. Beyond regular classes, the academy supports specialized instruction such as a women’s only program led by purple belt Kristien Kramar, which has notably increased female participation. Wrestling and competition-oriented training also have a place at Ground Zero, influenced by coaches like Anthony Petrella, whose wrestling credentials bring an aggressive, takedown-focused dimension to the curriculum. The gym welcomes drop-ins and is wheelchair accessible, reflecting a practical approach to accommodating a variety of practitioners.
