A family business that grows stronger with every generation.
Callens started out in 1966 as a one-man business built on a simple belief: deliver quality, take care of your people, and always be there for your customers.
Those values still guide us today, even though we've grown into an international group of companies with 430 employees.
The principles that guide our actions
Windy Moerman
Windy Moerman has been Co-CEO of the Callens Group, together with Annick Callens, since 2003. He grew with the company from within: in the early years he, like Annick, worked his way up through every department to acquaint himself with industrial processes and customer needs.
These days, he translates that broad experience into a distinctly strategic and operational role. Under the impetus of Windy and Annick, Callens grew into Belgium’s market leader. Presently, they are purposefully building on an international future for the Callens Group, with steps into the Netherlands and France for starters.
Windy Moerman believes in entrepreneurship with strong, forward-looking partners. He sees the energy transition as a unique opportunity to guide customers to sustainable, future-proof solutions.
