Dr. Woelke AG is an auditing and tax company based in Herford. Our links with our partnered company CONCEPTAX Siekmann, Janell und Partner mbB allow us to provide a comprehensive multi-disciplinary consultation, concerning company and business law. We offer services to companies of all sizes and private individuals, including some of the most prevalent companies in the region.

Our history

The origins of our audit, accounting and tax advisory firm date back to 1925, when the independent chartered accountant and tax advisor Dr. Franz Hein­rich Woelke opened an advisory firm. Over the course of the firm’s more than 90 year history, we have developed into a audit, accounting and tax advisory firm now known under the name CONCEPTAX Siekmann, Janell und Partner. The name of our firm’s founder is still part of our associated audit firm, Dr. Woelke AG.

What makes us different?

Our fundamental principles are that we are committed to the client and value each one highly. Our aim is to be a one-stop for advice and solutions, a reliable partner for all issues that require an interdisciplinary advisory approach. We offer practical and readily implementable solutions, and are open to new developments and creative solutions, without technical jargon. A key focus of our work involves comprehensive advisory services for Mittelstand companies.
