The beginning

Adopting the motto “Quality, progress and service”, Gustav Kessler senior took the brave step of going independent in 1905 when he set up Kessler & Comp. Nährmittelwerke. Today, the company is better known as KESSKO.

Expertise, market knowledge and an iron will to incorporate quality and progress into his service to his customers are the “good spirits” that accompanied the birth of the enterprise. Thanks to immense dedication on his part, KESSKO flourished from the humblest of beginnings and still continues to grow today, generations later.

Mr Kessler was a businessman, foreman and representative all in one, and he was never prepared to just carelessly jeopardise what he’d worked hard to achieve. It is therefore easy to understand why treating his customers well and maintaining good relationships with them was particularly important to him. He soon made a name for himself and, even more than that, he gained people’s trust – which is as vital today as it was back then when attempting to build a solid partnership.
