DORNKAMP stands for highly specialized, digital and efficient work. With proven experts in the respective field, which we document through doctorates, specialist lawyer titles, publications, specialist lectures and teaching activities. We support in:

For years, we have consistently relied on the digitalization of our law firm. Our working world consists of MacBooks, iPhones and AirPods, so that we can access our entire digital file inventory at any time and from any location and respond promptly – at the airport, on the train or at the beach. For this, we were awarded the law firm prize “LEGAL TECH” by the German Bar Association (DAV) in 2022.

More important to us than office space and suits are the training of our employees and the investment in software solutions. We create standards that get you to your goal effectively and at the lowest possible cost.

We probably do not correspond to the classic image you have of a law firm – and we do not aim to. All lawyers in our boutique have confidently chosen the privilege of convincing you with their competence and personality alone. You will see what we mean!
