Martina Patricia Steiner
Dr. iur., Attorney at Law, Certified Specialist SBA (Swiss Bar Association) in Swiss employment law, Mediator

Martina Steiner works solution-oriented and client-driven. She has over 15 years experience in the legal profession and was admitted to the bar in 2010. Before practicing in law firms, she worked at cantonal courts and at a public prosecutor’s office, both as an attorney and a law clerk. In addition, she gained courtroom experience and exposure to common law jurisdiction as a participant in the European Lawyers’ Programme at the Faculty of Advocates in Edinburgh, Scotland. Prior to joining HERZOG.law AG, where she manages - amongst others - complex litigation cases, she worked for eight years as counsel and attorney in the litigation and employment teams (Co-Lead) of the international business law firm Baker McKenzie in Zurich. Martina Steiner’s doctoral thesis on civil procedural law, her postgraduate degrees in mediation and forensics and her specialization in employment law (Certified Specialist SBA Employment Law) complement her working experience. Clients also benefit from her experience as a part-time judge and deputy to the president and vice-president of the Commercial Court of the Canton of Aargau and as a part-time president of a first instance Court. Martina Steiner’s main area of expertise lies in dispute resolution. She regularly represents parties before Swiss courts and authorities, supports clients in pre-trial negotiations, advises on avoiding litigation or arbitration and provides counsel on improving clients’ positions in potential conflicts before courts and arbitral tribunals. Often this involves cross-border issues. In addition to litigation, she advises clients in all matters involving employment law in Switzerland. Martina Steiner’s experience of working for commercial law firms, state courts and prosecution authorities, as well as for the Wealth Planning-team of a major Swiss bank during her studies, gives her a deep insight into the dynamics of law and its commercial implications. She understands the needs and challenges of her clients and supports them in an efficient and expedient manner.
