Ronald Janssen is a Founding Architect at ronald janssen architecten. Colleagues describe him as "Ronald Janssen, the best architect in the Netherlands ! I am not only stating this because I am an admirer of his design's, but also due to the fact he is a fantastic executor of his projects. On time, as agreed and always with a smile. I worked several times with Ronald and I have never been let down. A great person (and team) to have on your side in a challenging construction project. " and "The draftsmanship of Ronald Janssens designs often show an appearent clarity. The organisation of the programme is of obvious straightforward intelligence and the buildings reveal a maticulis technical skill. Quality is consistent through all levels of scale due to his persistant attitude towards a high standard of architecture. As may seem contradictory to this strict approach the resulting architecture holds a strong sense of mystique and lasting charme. He is a social animal and has a great sense of (self-) humor."
