About Maren Tamke

Maren specialises in German and European antitrust/competition and mergercontrol law.

Whilst based in Berlin, and throughout her secondment to the London office in 2015, Maren has worked across many industries, with particular experience in the following sectors: consumer products, e-commerce, insurance, media and healthcare.

Maren advises clients on complex transactions, high-profile cartel investigations, dominance cases, follow-on damages claims and compliance matters. Her approach is to team up with clients, to make their cause her own and to deliver not only excellent but also practical legal advice. Based on her vast experience gained in the course of merger control and conduct cases, as well as compliance work, she understands the workings and needs of businesses.
