‘Quick response with practical, directly applicable advice. Provides confidence in critical (legal) situations and makes it possible to keep communications with our counterparties open.’

‘Huge knowledge in the field of IT and privacy law. There is a lot of experience in thinking along with the company, whereby not only the legal, but also the business interests are taken into account in advice.’

‘Mark Jansen: You cannot find more knowledge about privacy law in one person. In addition, Mark has the ability to provide quick and practical advice, despite the fact that it concerns very complicated matter. At any other office I would get huge memos, Mark has the power to advise to the point without a lot of ballast around it.’

Ernst-Jan van de Pas: You notice in the way in which he contributes ideas that Ernst-Jan has a lot of experience, not only as a lawyer, but also as an arbitrator. I appreciate not only the content of the advice, but also the willingness to take up matters in the short term.’

‘Highly qualified and exceptionally high level of quality.’

‘Strong knowledge combined with practical thinking and great collaboration on cases. I like the way Dirkzwager can think both on the business side and the legal side.’
