Our firm


For us, responsibility means: Create value and preserve it

The philosophy of our partnership can be summed up in three words:

“Values People Strategies”

Because that’s what our daily work is all about: Using suitable strategies to create and preserve value in the interest of our clients. Responsible working practices are a pre-requisite for this. And what’s more: Responsibility is the priority for all our thoughts and actions.

In relation to our clients, this awareness of responsibility manifests itself in a holistic range of forward-looking advisory services that are characterized by their individual nature, high-level professional expertise and a maximum degree of legal security - and that are certified in accordance with DIN EN ISO 9001.

We also treat our employees responsibly. With a comprehensive range of education and further training packages as well as an attractive benefit program, we have created an environment that supports the professional and personal development of every single individual.   

Our values:

  • We work with our hearts and our minds.
  • We take care of our clients and our employees.
  • We think outside the box.
  • We deal with our clients and employees openly and reliably.
  • We treat our clients and our employees fairly and respectfully.
  • We are loyal to our clients, colleagues and partners.
  • We act on the basis of shared values.

Time and time again, our clients and employees provide us with confirmation that we are on the right track with this conception of ourselves. We are especially proud of the respect we receive from other sources: e.g. tax authorities, courts, legal chambers or lending institutions, among whom we enjoy an excellent reputation.


For us, responsibility means: Teams of experts for every client

For every client, we put together a bespoke team that is composed of experienced public accountants, legal attorneys, tax advisers and company consultants. This team is led by a person responsible for the client, who is available as the client’s sole point of contact. In order to ensure that the consultation takes place on a level playing field, this person is one of the partners in our partnership.

PKF WMS has an outstandingly flat and efficient organizational structure. The consultants are assigned to individual independent teams that specialize on certain areas of expertise.

The history of PKF WMS Group

Only few auditing and business consulting firms in the region have such a long tradition as PKF WMS Group. We have been taking care of family-run enterprises, entrepreneurs and freelancers successfully for 90 years.

The original firm was founded by Hermann Wilker in 1931. Over the years, further partners joined and “WMS” (which originally stood for the owners Wilker, Müller, Schnüpke) was created. The years thereafter were marked by continuous growth. Today, PKF WMS Group has more than 300 employees, of which more than 50 are industry professionals. We are one of the most powerful partnerships in the Chamber of Commerce region of Osnabrück-Emsland.
