Treuhand – Enjoy business

About Us

Developing and implementing optimal solutions – that is our goal. With this aim the Treuhand team supports decision-makers in all questions concerning auditing, tax consulting, legal advice, management consulting and IT consulting.

We master this with sound, up-to-date knowledge, many years of experience and lots of enthusiasm for our remit. We understand, down to the smallest detail, what we are doing. We don’t supply paper, but solutions and we use planning leeway – including across national borders. This is how we commit ourselves personally to the self-employed, entrepreneurs and decision-makers, so you can fully concentrate on your core competences and successfully run your company.


As the leading group of advisory firms in the Weser-Ems region we are the premium partner of the Mittelstand in mastering current and future challenges. Our comprehensive spectrum of services consisting of auditing, tax consulting, legal advice, management consulting, IT advice and special services covers decision-makers’ requirements in almost all questions of corporate management – and does so at the highest level of quality.

We’ll secure your legal, tax and financial management frameworks, especially in growth, crisis, succession and other demanding phases of the company. Our particular strength is tax-orientated planning advice. Direct contacts providing all-round advice and viewing the client as a whole long term and interdisciplinary cooperation between our specialists at the same time lead to pragmatic and reliable solutions.
