Who we are
Our Story.
In 2015, a Tasmanian project had a large and complex problem they needed help solving. They needed someone they could depend upon; someone who had the ability to tap into a wide range of expert skills and knowledge; someone with a deep understanding of the Tasmanian business and community landscapes. And they needed it solved quickly, professionally and collaboratively. They knew just the team to turn to – John and Kerrie Mazengarb, who were already well known for their strategic thinking and no-nonsense approach (well, perhaps just a little bit of nonsense!). And so, GSD Advisors was born.
It was by no means an easy birth – long hours, late nights and many, many cups of coffee. But John and Kerrie brought their own unique style to the world of consulting, rolling up their sleeves without hesitation and embedding themselves in the project to better understand where it was – and where it needed to be.
