Mr. Störing and Mr. von Bühler are two outstanding lawyers, with a sense for the requirements of a globally active company. They develop pragmatic solutions and are always thinking along, which makes working with you a real pleasure.
Helping you succeed in tomorrow's world
When the GDPR entered into force, a few global players were ready while many organisations rushed to install basic compliance structures. With the AI Act, history is repeating. As part of a specialised team, I help clients break that pattern by moving from reactive fixes to durable, risk‑based governance that enables innovation.
Specialising in data protection and the AI Act, I assist building sustainable, resilient compliance frameworks and keep them current as laws and technologies evolve.
Only those who understand risks, recognise them early and assess them correctly can make reliable decisions and avoid unpleasant surprises.
