A FAMILY BUSINESS
The culture at the GUILLIN Group and its success are the direct legacy of its founder’s values and beliefs.
Team spirit, excellence, performance, respect, responsiveness, a sense of service: the road map for this enterprising journey. Today, these values have become incorporated into guiding principles that continue to direct and encourage the 3,000 people who make up the Group.
Loyal to its origins, the Group has built its headquarters close to the family base, and the Guillin family has always remained the main shareholder.
A DIVISION-BASED STRUCTURE
To unite and harmonise operations of its 32 companies spread around the whole of Europe, the GUILLIN Group relies on its holding company, on which the Group’s strategic functions are centred.
The companies are organised by discipline and by market, with designated directors to ensure synergies are utilised in all directions.
