David Muller possesses expertise in continuous improvement, mining, business process improvement, six sigma, management and 45 more skills. He is proficient in English. Colleagues describe him as "I have known of David (Docker) a couple of ways, first was as an organiser and driving force behind the local Masters Australian Rules football team and secondly as a work colleague of a close friend. In all my dealings with David and all that I have heard of him, he has been an example of the kind of person most aspire to be like; for most it would be hard work, but for David it is just who he is. David always conducted himself with the utmost integrity and dedication, not just in coaching and organising football, but as being a friend and mentor. His ability to inspire others to seek more from themselves was something I personally benefited from not just for football, but life in general. I was also lucky enough to witness the very beneficial impacts David had on many others. His leadership is truly authentic and his ability to perceive the opportunity for, and to inspire a change for the better is a pleasure to be involved with. I can hardly recommend David enough for his ethics, leadership, humanity and intelligence. He is a pleasure to know. "
