Professora Xan is a Brazilian Jiu Jitsu black belt and is co-head instructor of Atomic Jiu Jitsu Brisbane. She teaches every evening class and works directly with students from their first lesson onward.
Xan is both a qualified physiotherapist and an exercise scientist. Her understanding of movement, joint mechanics, and load management informs how techniques are taught and how training intensity is structured inside the academy.
Having trained and competed since white belt, her coaching emphasises technical efficiency, body positioning, and safe application of pressure. Students learn how to train with control, maintain awareness of training partners, and develop skill without unnecessary physical risk.
Professora Xan plays a central role in student development, helping beginners establish correct movement patterns early and guiding experienced students toward precise and effective execution.

Professor Tim is a Brazilian Jiu Jitsu black belt and is co-head instructor of Atomic Jiu Jitsu Brisbane.
He teaches all morning classes, and evening classes at the academy alongside Professora Xan.
He has trained and competed since white belt and built the Atomic curriculum around structured, repeatable systems rather than athleticism or improvisation. Classes emphasise mechanics, timing, pressure, and positional understanding so students develop skills that work consistently against resisting partners.
Professor Tim’s coaching focuses on clarity and progression. Techniques are taught as connected systems rather than isolated moves, allowing students to understand not only what to do, but why it works.
At Atomic Jiu Jitsu Brisbane he is responsible for curriculum design and daily instruction, ensuring students improve methodically in a controlled and technically focused environment.
