The founder of Salvos, Eino Koskelo, was born in Siikalatva, in the village of Lamu, in Kytölä in the 1950s. Already as a young boy Eino was interested in the qualities of wood and searched for a suitable ice hockey stick for yard games from the forest. Around the same time a local carpenter, Eino Juhola, created anything from wood for the villagers: tubs, gunstocks, and other utensils. In the 1980s Eino Koskelo gave up on farming. Eino Juhola took him under his wing to build outdoor saunas and cabins – the master and the apprentice met.
Soon Eino Koskelo started building saunas, modelling them on the sauna his grandfather built in the 1930s. In addition, granaries, cabins, machine sheds, and detached houses were completed according to the wishes of the customers. As the business grew, Eino got his two eldest sons to help. Soon the business also employed about ten workers.
