Grant Killen

Grant began his career as a Royal Australian Navy Clearance Diver and participated in several overseas deployments before fulfilling contracts for the US State Department in Iraq.

In 2005, Grant joined the Queensland Police where he worked and instructed within a variety of specialist positions, including the Explosive Ordnance Response Team (EORT), and Close Personal Protection Teams who are responsible for the safety and security of political figures and visiting dignitaries.

Grant moved on from the Police, and consulted as a senior security and crisis management advisor in the mining, oil and gas industries. Grant was pivotal in developing comprehensive security and emergency management capabilities in challenging, high-risk environments.

After observing a lack of tangible safety and security solutions in the family and domestic violence sector, Grant formed Concentric Concepts.

In the years since the inception of Concentric Concepts, Grant has forged an exceptional reputation within the family and domestic violence sector, known specifically for his professionalism, and empathy towards victim survivors.

Grant understands the needs of people in crisis, and the requirements to provide an immediate response.
