Early Life and Education
Stefano Pessina was born on June 4, 1941, in Pescara, Italy. Raised in a family that valued education and enterprise, Pessina grew up with a keen sense of discipline and intellectual curiosity. His early life in Italy was marked by a deep interest in science and engineering, leading him to pursue a degree in nuclear engineering at the prestigious Politecnico di Milano.
While many of his contemporaries entered academia or scientific research, Pessina’s sharp analytical skills and fascination with problem-solving guided him toward a career in business. His engineering background later proved instrumental in his strategic decision-making—helping him analyze complex systems, mitigate risks, and execute global business transformations with precision and confidence.
Beginning of Career and Early Success
After completing his education, Pessina began his professional journey in the field of market research. However, his true calling came when he took over his family’s pharmaceutical wholesale business in Naples in 1977.

With visionary foresight, he merged the family business with other regional distributors, forming larger networks that could operate on an international scale. His early ventures, including Alleanza Salute and Alliance Santé, positioned him as a pioneer in pharmaceutical logistics and wholesale management.

This merger was the beginning of his broader ambition to unify healthcare distribution across borders.
In 2006, Pessina orchestrated one of the most significant deals in business history: the merger of Alliance UniChem with the British retail pharmacy chain Boots. The resulting entity, Alliance Boots, became a powerhouse in both retail and wholesale pharmaceuticals.
