Growth that keeps us close
Based on that conviction, we are taking the next step. Van Oers is merging with HLB Den Hartog, a strong and well‑established accounting firm in the Rotterdam and The Hague regions. We deliberately refer to this as a merger: a conscious choice to join forces, strengthen each other, and build together on what already exists.
Local roots, collective strength
The world of entrepreneurs and organisations is becoming increasingly complex. The need for expert, reliable, and accessible advice is growing. This is precisely when a strong local presence is essential. By merging with HLB Den Hartog, we are strengthening our roots in economically important regions, while remaining fully committed to quality, culture, and personal attention.
HLB Den Hartog knows the Rotterdam and The Hague regions inside and out and has built a strong network there. Van Oers brings scale, expertise, and broad professional knowledge to the table. Together, we ensure that clients can rely on continuity, accessibility, and advice that is tailored to their specific situation, both now and in the future.
What our clients and business partners can expect
For our clients and business partners, the core of our services remains unchanged. They will continue to work with familiar points of contact, receive the same high‑quality advice, and experience the same personal approach. What will change is our ability to deliver on that promise even more effectively and across more locations. By being closer to our clients, we can respond quicker, share knowledge more effectively, and further strengthen our support.
Building the future together
This merger is also an investment in the future of our organisation and our profession. It creates opportunities to further deepen our expertise, expand collaboration, and continue to attract and develop talent. For our colleagues, this means new perspectives within an organisation that places a strong emphasis on quality, commitment, and professional development.
By merging with HLB Den Hartog, we are consciously choosing sustainable growth. We are growing to stay close: to our clients, to our colleagues, and to the core of who we are.
