Charles Kieffer, the founder of the group, began his activities with photography and a few years later entered the field of copying to become, today, a company expert in the digital accompaniment of companies and the improvement of the work experience. Charles Kieffer’s philosophy of “a healthy mind in a healthy body” led him to open the Sportcenter in Kockelscheuer in 1980 and then 4 fitness centres across the country. His ideas gave birth to our current baseline “healthy people, healthy business“. Since 1946, the company has grown significantly by keeping up with the latest technological and sporting innovations.
