Young Professional Stories
-
An interesting internship at a complex worksite! It was neat that they considered my ideas, amongst others at worksite meetings, and that they also gave me a fair amount of responsibility. I didn't mind the early mornings one bit and I was proud to put on my jacket & helmet. That says it all, I think!

After my internship on the WarmtelinQ project in Delft, Denys hired me as a site manager. I'm really looking forward to working on all those interesting projects and I will tackle future challenges with great enthusiasm.
