De Nieuwe Zorgorganisatie (The New Care Organization) has become acquainted with several Legaltree partners in multiple issues and proceedings and around multiple procedural legal issues. First and foremost, the expertise of Jan ter Horst, Willemijn Lever and Sander Oorthuys stands out. Their advice is 'to the point', which has helped our organization to focus better and has enabled it to act and act at a higher level. In procedures, there is always an open eye for the interests of us as clients, but the balanced advice is also determined by risk assessment and reasonableness. As a result, we as Legaltree clients have always been optimally supported.
