From Global Finance Leadership to Local Legacy Building.

Ronnie Dyne’s career traversed the landscapes of finance and real estate in South Africa, The Netherlands, and the United Kingdom before establishing Stonebridge in Australia. Initially serving as the CFO of an international family group, Ronnie’s role evolved with the changing dynamics of business, leading to the formation of Stonebridge Family Office in 2000.

Today, Stonebridge is a trusted partner managing the financial destinies of six families, collectively overseeing assets surpassing AUD 1 billion. In 2021, Saul Dyne joined our ranks, bringing with him six years of experience in auditing and accounting. As a member of Chartered Accountants Australia, Saul spearheads the implementation of cutting-edge technology platforms, ensuring the seamless operation of our services.
