At a young age, brothers Frank and David were introduced to the world of cleaning by their father, Frank B. Cullen. They worked from the ground up, learning the trade along the way.
With a hands-on approach, our depth of knowledge, commitment and passion to always do the best job ensures that CCS deliver above and beyond industry expectations.
Frank B. Cullen founded Cullen Cleaning Services in Ireland, laying the foundation for what would become a multi-generational family business.
Brothers Frank and David joined the business, learning the trade from the ground up alongside their father.
Louise Cullen joined the family business, bringing fresh energy and vision. She would go on to become CEO, leading CCS into its next chapter of growth and innovation.
