He is listed amongst Germany’s best competition lawyers by German nationwide daily Handelsblatt in 2022. He is also been named a “Future Leader” in competition by Who’s Who Legal.  Most recently, he was ranked by Chambers Global which reports that clients state that "he is technically excellent and always provides pragmatic advice”.

Mr. York has significant experience in advising multinational corporations across a broad range of industries, including automotive, air cargo, biotechnology, broadcasting and media, chemicals, consumer products, energy, financial services, manufacturing, pharmaceuticals and telecommunications. Mr. York is a frequent speaker and author on antitrust/competition and foreign investment-related topics.
