We are Newtone. The consultancy and accountancy firm for the enterprising Netherlands. Created in 2024 by the merger of Koenen en Co, HLB Witlox Van den Boomen and PKF Wallast. With over 1,100 employees from 13 branches in and twelve multidisciplinary offices located in the Netherlands’ most vibrant regions.


Stronger through regional leadership

Our combined strength provides regional leadership. Logical. Because from our core strengths – in-depth professional knowledge, customer focus and multidisciplinary thinking – we strengthen our network, increase our expertise, attract talent and achieve scale.


Newtone: a new name with familiar power.

Newtone is futureproof. That characteristic comes from our national span and regional strength. But also from our national scale and international network. From this hybrid way of organizing we continue to optimize our high-quality, broad and innovative services. Including the familiar human contact. Including an office always nearby. Wherever our distinctive services are needed. Exactly where we are.
