What is tuomi?

tuomi was founded by Arja Tuomi Roos in Trier in 1995. And we are proud of the fact that today we are still serving customers from those early days. We have a very low fluctuation, not only among our employees but also among our customers. Our customers are internationally active. Many of them are based in Luxembourg. So, in order to provide optimal service, we founded a new company in 2005, which is based in Luxembourg.
