Data-driven multidisciplinary consultancy in the financial, tax, legal and HR field

About us

Listen… we are joining forces.

The world expects a lot. From you. And from us as well. Further digitalisation, a growing demand for expert advice, and the more and more complicated regulations are straining us more than ever. Our goal is to offer clients the best possible service and multidisciplinary advice at all our offices, and also to create new opportunities and career chances for our employees and for up-and-coming talent like you. That is why HLB Witlox Van den Boomen and Koenen and Co made a decision in 2023: we are joining forces!

Our merger means that you will get to work in an organisation with over 1200 employees and over 7500 clients divided between ten multidisciplinary offices in Brabant and Limburg. In other words, a force to be reckoned with in the top-10 largest consultancies in the Netherlands. We offer all the benefits of a major corporation, while still maintaining our authenticity. Our clients and employees will always get that feeling of being in a leading regional office. With the top-notch multidisciplinary advice of a leading advisory company, but where you and your trusted client team will always know the client by name. En we you. Here, you will never be just a badge number. As an employee, you get to choose your preferred and most efficient working method.

For now, we will be ‘Living apart together’, trading under both brand names, HLB Witlox Van den Boomen and Koenen and Co. But soon, we will merge into one organisation to become the leading multidisciplinary consultancy in the Netherlands. And we would like you to be part of it. Will you join one of the partners for a cup of coffee at one of our regional offices?

What are your sustainable initiatives?

HLB Witlox Van den Boomen en Koenen en Co is co-founder of the platform Green by Blue. This is a platform that offers accounting and consulting firms expertise, methods, training and capacity to prepare the Netherlands for the sustainability transition.
But how does this cooperation work?
