Employee review: Niels - R&D Scientist

"Bertels has a warm atmosphere and the activities, such as Friday afternoon drinks and staff parties, are always fun. You immediately notice that you are working for a family business. In R&D we develop new products. But we also always develop existing products further. Stagnation means decline! We also monitor the quality of the products, from the raw materials to the end product. I feel completely at home here!"
