I have gotten to know Martijn as a committed, enthusiastic but above all expert trainer. Martijn knows how to ask the right questions, clarify the relationship between practice and literature and link advice to this. Martijn has a nice way of communicating which makes you feel at ease with him quickly, his humor and empathy ensure a pleasant interaction.

Mr. D. Kleppe - CFO, Vendor

I have experienced Martijn as open, to the point, a peoplemanager with excellent communication skills. He has the ability to communicate complex matters in a simple way so people are aligned.

Mrs. M. van Zantvoort - CCO Healthcare informatics, Philips

Working with Martijn is a joy! What surfaces immediately is his integrity and his sense of teamwork. His questions are not seldom probing and challenging: with the aim to raise the bar to new levels or put a spotlight on new perspectives. He has a good sense of what is urgent and what is important. Takes the time to get to know the people he works with, and builds strong relationships. His enthusiasm and sense of humor can give the needed lift in heavier circumstances, and it enables Martijn to create new opportunities to better the position of all in a certain situation.
