The company was founded in Parma in 1935 when Giacomo Chiesi, a chemist who dreamed of doing research, bought the Laboratorio Farmaceutico Parmense and embarked on his entrepreneurial adventure. In the years that followed, sons Alberto and Paolo led an ambitious expansion and internationalization process that led to the development of a robust product portfolio and distribution in over seventy countries. Today Chiesi is still very much a family-led organization that embraces its entrepreneurial roots. The company continually strives to not only develop innovative solutions for its current customers, but is also exploring cutting-edge areas such as regenerative medicine and biotechnology.
