Our history

Our business was established in 2009 by two founding Partners, Rory O’Connor and Andrew Marsden. In those first twelve months, our business established itself as a strong probity practice and in 2010, the business expanded into Assurance services.

Since those early beginnings, our business has grown from strength to strength, expanding our service offerings as our clients kindly gave testament of the value and expertise we bring to each of our engagements. From our first two offices in Sydney and Melbourne, our practice has grown with the opening of offices in Brisbane, Canberra, Adelaide, Hobart, Parramatta and Perth.

Our strength comes from our ability to attract a large talent pool of SMEs from different educational backgrounds and industries. Our practitioners are our most valuable asset. Through harnessing their deep expertise, we form multi-disciplinary teams focussed on finding solutions to the most difficult of business challenges.

Our practitioners have been assisting organisations enhance their systems and procedures, strengthen controls, reduce costs and improve operating performance for many years. Meet the Service Line leaders behind our teams.
