Wiersholm‘s practice spans the full gamut of contentious and non-contentious TMT matters. The practice is led by a capable quartet of partners: Hans Erik Johnsen, who acts for service providers, technology developers and media companies on all aspects of TMT; Anne Marie Sejersted, who acts for renewable energy, medtech and offshore clients; Rune Opdahl, who delivers ’practical solutions’ across a broad range of work including data protection and media law; and Kai Thøgersen, who takes point on M&A and corporate matters. The team also includes Theresa Schumacher Walberg and Emilie Sverdrup who are recommended for IT contracts, and data protection specialist Line Helen Haukalid is a key contact for GDPR mandates. Carl Emil Bull-Berg departed in February 2024.
