Our Instructors

Our Instructors are fully qualified KMG Instructors with years of experience in Krav Maga.

All our instructors have undergone a rigorous 180hr, 22 day course to become a Krav Maga Global General Instructor. As KMG Instructors our Instructors must attend annual Instructor updates with KMG in order to sharpen skills learnt and maintain an up to date understanding of Krav Maga.
