Every academy creates its own unique atmosphere. A great deal of this is based on the individual and collective calibre of its instructors. Learn about Defiant Jiu-Jitsu's instructors.


Jiu-Jitsu Lineage

When it comes to Brazilian Jiu-Jitsu, instructor lineage matters. We're proud to be able to trace our line all the way back to the founders of the martial art.

Our students are given the option of registering with the IBJJF so their rank is recognised internationally, regardless of whether they wish to compete or not.
