"In the 1950's, Douglas McCallum presented to Gordon Marr as a sub-contract boiler-making service. A bond built on understanding and trust saw AD McCallum and Son and Marr Contracting begin an association that has endured through 60 years and 3 generations. And today still sees both companies doing business together. In the beginning, ADM operated out of Marr's premises. In the late 60s ADM moved to their own premises at Villawood, then to Windsor and to their current location at Wilberforce. The distance between them has not proven to be a barrier to their association, as Marr today still appreciates the efficiency and capabilities of the McCallum team."
