Mark is currently the Managing Director of Geraldton Brick and also a Director of WA Fuel Supplies. He holds a Bachelor of Civil Engineering from UWA and an MBA from Deakin University. Mark has also completed the Owner President Management program at Harvard University. 

After an “apprenticeship” in the civil contracting industry, including time spent with the Australian Army, Charles Hull Contracting, and Ertech, Mark founded and grew a successful civil contracting company that was primarily based in the Pilbara, with operations across WA. 

Mark later sold this company and purchased Geraldton Brick, a manufacturing business. 

More recently Mark became a founding shareholder of WA Fuel Supplies, which has grown to become the largest independently owned fuel distributorship in WA.

Whilst family is, and always will be, his #1 priority, Mark’s passion lies in business. More specifically, this passion is underpinned by the desire to be involved with the development and growth of people (at all levels) within these businesses. Consequently, when offered the opportunity to join the Board of Motivation Foundation, Mark saw the work of the Foundation in training youth in life-ready skills, which provided him the opportunity to give back at the ground level to an industry in which he has been involved for a significant portion of his career.
