What does it take to build one of the most successful retail empires in Australia… and sustain it for decades?

In this episode of A Life of Greatness, Sarah Grynberg sits down with Mario Tascone, Deputy CEO of Retail at Chemist Warehouse, a business that disrupted an entire industry and grew into a global powerhouse with over 600 stores worldwide. From humble beginnings working in a single pharmacy to helping lead one of the country’s most recognisable brands, Mario shares the mindset, risks, and relentless work ethic behind the journey.

This conversation goes far beyond business. Mario opens up about the influence of his immigrant parents, the discipline that shaped his success, and the personal transformation that saw him completely change his health, lose over 25 kilos, and run the world’s biggest marathons. He reveals why discomfort is the key to growth, why consistency beats talent, and how never giving up has been the foundation of everything he’s built.
