I am an experienced conflict management and dispute resolution lawyer who prioritises identifying the best solution for our client in every situation. When the circumstances call for it, I am committed to finding the right building blocks for a case and defending our client’s interests in adverse situations.

My pragmatic and solution-oriented approach stems from my versatile background. I started my career practicing M&A and general corporate advisory, and I have a strong generalist background in business law. From this generalist foundation I have since focused my practice on conflict management and disputes, including handling proceedings before arbitral tribunals both in domestic and international cases, general and administrative courts, and mediation. In addition, I am experienced in corporate governance and compliance matters, e.g., supporting clients in internal investigations and other challenging situations within their organisations. I have also assisted clients in criminal proceedings with a business law connection.

Before joining Wiidare, I served as the Secretary General of the Finland Arbitration Institute (FAI). As Secretary General, I was responsible for leading the team at the Secretariat and for developing and coordinating the Finnish and global activities of the FAI. I was also tasked with the administrative functions of the Redemption Board of the Finland Chamber of Commerce, which handles cases concerning the redemption of minority shares pursuant to the Finnish Companies Act. My previous position equipped me with a thorough understanding of the needs of businesses and the service offering they require to succeed.

I am an active member and well connected in the Finnish and international dispute resolution community. I also regularly lecture and give trainings on various conflict management and dispute resolution topics.
