Tatjana Sachse

TATJANA SACHSE co-heads the international policy group at Sidley Austin’s Geneva office.

She offers strategic legal and public policy business advice and lobbying services to multinational companies and trade associations on all aspects of international regulatory and trade issues that impact a broad range of industries, including: manufacturing, luxury goods, interactive entertainment, biotechnology, pharmaceutical, medical device, agriculture, and food and beverage.

Her unique approach provides Geneva-based lobbying services with a legal twist, offering a 360-degree approach.

Tatjana has helped clients broaden — or, at a minimum, maintain — market access, optimize supply chains, secure intellectual property protection, and obtain the acceptance of new technology solutions.

Given the proximity to negotiations in Geneva, Tatjana is able to always keep a finger on the pulse of negotiations. She represents commercial clients before governments, as well as intergovernmental and UN organizations, including the World Health Organization (WHO), World Intellectual Property Organization (WIPO), the World Trade Organization (WTO), the UN Framework Convention on Climate Change (UNFCCC), and the UN Conference on Biological Diversity (CBD).

Given her previous experience as in-house corporate counsel, Tatjana has always had a keen understanding of the needs of a wide range of international commercial clients and industries she is serving.

In addition to her experience in private practice, Tatjana completed an internship (stage) with the Directorate-General for Trade of the European Commission.

Tatjana is a Fellow of the Institute of International Economic Law at Georgetown University Law Center, where she graduated with distinction, and holds a Certificate in WTO Studies.

She speaks German, English, French, and (Brazilian) Portuguese.

In November 2022, Tatjana was appointed as the lead spokesperson and counsel for the Global Video Game Coalition (GVGC).
