How it all started...
With the arrival of several Dutch Dairy farmers in Portugal in the late 90’s, Diessen, a veterinary practice from Holland, started also in the south of Portugal. In 2000, this practice would come together with another one from Tilburg. At this time, Henk Dijk, took over the “Portugal project”. He would make of Diessen Serviços Veterinários the company we are today… In 2006 Carolina joined this project and at the same time the company separated from the actual Dierenartsen Midden Brabant. Henk and Carolina worked side by side until 2011, year in which Henk would retire and follow new projects… In 2013 it was time for Bruno to join us. We have been growing ever since. Diessen is nowadays the result of Henk’s tireless work, who got together so many of our clients today and who was mentor of our way of work.
