BRINGING PEOPLE together to discuss and negotiate a path forward is part of my DNA and is the reason Cornerstone Group was established in 2012.

Built on a foundation of ethics and facilitating outcomes, Cornerstone transformed what I already did as a business leader and member of politics into a viable and valued business.

In the mid-90s, electronic communication was becoming an essential part of the global supply chain. As a Director of the Australian Federation of Freight Forwarders, I was central to the development of an international agreement on process implementation, bringing global leaders to the table to implement electronic data interchange initiatives.

My experience also earned me a place on the negotiation team as Australia worked with both China and India in securing investment for infrastructure development.

As a former Director on the State Executive of a national political party, I observed first-hand how the interplay and two-way communications between business and government unfolded. Bringing people, business and government together via the Cornerstone Group was a natural evolution.

My motivation also comes from my early family life, and from my father’s dedication to charity work. This saw me involved in advocacy from a young age. Today, the Cornerstone Group still focuses on giving back to charities that our staff and clients believe need our support, including through pro bono services to the not-for-profit sector.

I believe that a business must set out to build ongoing and deep relationships with government, the community and the people in it. And to continue facilitating meaningful conversations between these stakeholders through good and bad times.

It is upon these foundations that the Cornerstone Group was founded, and against which we measure ourselves every day. Cornerstone is much more than a service provider to local and international businesses – we are proud to be the source of real time intelligence and insight for our clients as they grow their businesses in Australia.
