Testimonials
Collated independently by Legal 500 research team.
- An excellent team that puts excellent knowledge, skills, and drive into practice. Flexible and service-oriented. Work is approached in a structured manner and organized at the necessary level. We truly operate as a team (lead, senior, and junior lawyers).
- The team members have up-to-date knowledge of not only M&A, but also a good understanding of other areas like W&I insurance and competition.
- I would like to express my sincere appreciation for the individuals at De Brauw. The team combines deep legal insight with strong oversight of complex matters, and their collaboration — both internally and with our own team — is smooth and highly effective. Everyone is given the space to contribute, and each person is fully committed to our shared goal. This creates a strong sense of joint ownership and focus throughout the process. The partners, in particular, operate at an exceptional level — combining strategic thinking with hands-on involvement, and setting a high standard for the entire team. It has been a pleasure to work with such dedicated and capable professionals.
- The team is hands-on and well-organized.
- Individuals with long-lasting relationships with our company and experience in our industry. 100% commitment.
- The team is very responsive, detailed, and accurate in the work that is produced. The quality and speed combined are really the strengths.
- As a lead, Jasper van Uden is always in control, maintains an overview, and is effective in advising clients and their relationships with government agencies and other organizations. He's friendly, yet decisive. Welmoed Willemse is our first point of contact, and we couldn't ask for better. She's incredibly sharp on the content and also has a strong understanding of the process between organizations and individuals.
- Actively thinking along with the client on the best strategy to use, providing clear insights on pros and cons. Proactive in defining, planning, and executing actions to be taken. Keeping a sharp eye even in times of very serious workloads and the pressure of deadlines in multiple workstreams.
- I've worked closely with Mr. Jaap Barneveld and Mr. Jasper van Uden. The first one in the field of M&A and the other in the field of public law. Both combine their theoretical knowledge very well with practical work. Always looking for the best result for the customer, but also always aware of risks or sensitivities.
- Well-informed, thorough, client-based, and reliable on goals and targets.
