With more than twenty fours years of leadership and management experience under his belt in both public and private sectors, David has drawn on the experiences he has gained to carefully lead and manage Caledonia Group through more than twelve years of successful targeted growth. In line with his personal values, David takes a clear and straightforward approach to managing the business. Starting with a single entity in South Australia that provided a scaffolding service only, David has led Caledonia Group through several phases of growth, where each phase presented its own unique challenges. Today, Caledonia Group comprises five separate entities spread between Western Australia, New South Wales, South Australia and New Zealand, employs approximately 450 staff and is on a steady trajectory to reach $100 million turnover. Services today include, scaffolding, insulation and cladding, design & engineering, predominantly in the mining, industrial and oil & gas sectors.

The growth of Caledonia Group required continual re-structuring of the organisation, whilst implementing many business and performance improvements along the way, particularly in relation to accounting, banking and business diversification. Priding himself on integrity and always providing the best service to clients, David believes in bringing people with you rather than forging ahead on his own and several of Caledonia’s current leaders and managers have grown with the business over the years and are now embedded in senior positions. However, when the Group needs new talent, David also believes in bringing in key people in key positions at the right time and place.

To assist with the challenges of growing a business, David undertook further study and completed a Master of Business Administration degree, specialising in strategic business planning and strategic human resources management. This sparked the development of Caledonia Groups Advisory Board (2015), in line with good corporate governance principles for privately owned businesses and led to the development of Caledonia’s Strategic Plan. The strategic plan is refreshed annually, and to this day is the keystone for continual safe and successful growth and is the driver of performance.

David also provides his strategic insight and expertise to another organisation, Sunrise Ag Group, through his position on the Advisory Board. Sunrise Ag Group is a large privately owned group of farm machinery dealerships with locations in Mildura, Renmark, Berri, Ouyen, Griffith and Swan Hill.
When David is not focused on work, he can be found spending time with friends and family and enjoys leading a balanced lifestyle at his home in South Australia.
