Since our foundation in 1982, we have amassed a wealth of experience and our organisation has developed constantly. As a result, we know exactly what challenges, issues and problems can arise in the world of personnel and finance. In fact, we highlight them before they start to have an impact on your business. So we are always there before you actually need us, and you can focus on what you enjoy doing most – running your business.

Our organisation as it is today

Koenen en Co has developed into a large, professional full-service finance and consultancy organisation with 250+ employees, 11 partners and a considerable market share in Limburg and South-East Brabant. And – also very important – our offices in Maastricht, Roermond, Venlo and Helmond mean that we are always close by.


Koenen en Co was founded by Jac Koenen in 1982. As a born entrepreneur, his goal was always to set up his own company. He developed a one-stop-shop concept and set out on a mission to open offices in the seven major cities of Limburg.

His first office was located in Panningen. That first office was quickly followed by others in Roermond, Venlo, Venray, Heerlen and Sittard. The range of services was also expanded, and tax consultants were added to the team. Unfortunately, Jac passed away in 1994. However, the partners were able to complete his life’s work in 1999 by opening a branch in Maastricht, where we are still located today.

Dit is onze historie

Hoewel we het liefst vooruitkijken, is onze geschiedenis minstens zo belangrijk. Die maakt immers wie we zijn. We schrijven 1982 als Koenen en Co wordt opgericht door Jac Koenen. Zijn ondernemerschap bracht hem op het idee een eigen kantoor op te zetten. Met het door Jac ontwikkelde one-stop-shop concept wilde hij zich vestigen in de zeven grote Limburgse steden.

Zijn eerste kantoor opende Jac in Panningen, waarna Roermond, Venlo, Venray, Heerlen en Sittard al snel volgden. Ook het dienstenpakket werd uitgebreid. Naast accountancy en administratie ging Koenen en Co zich bezighouden met belastingadvies.

Helaas kon Jac niet lang genoeg genieten van zijn zakelijke succes. Hij overleed in 1994. De partners zetten het bedrijf voort en hebben in 1999 zijn levenswerk kunnen voltooien door de opening van een Maastrichtse vestiging. Hier zijn we nu nog steeds gevestigd!
