Iris Brisson

Senior Associate, Member of the Finnish Bar

I advise our clients in assignments relating to dispute resolution. My main areas of practice are domestic and international court and arbitration proceedings.

Prior to joining Castrén & Snellman, I worked as an associate with the dispute resolution team of another Finnish law firm and as an in-house lawyer for a global company manufacturing mobile phones. During my studies, I gained valuable work experience by working as a trainee at reputable Finnish law firms and by completing an internship with one of the case management teams of the ICC International Court of Arbitration in Paris.

I hold a Master of Laws degree from the University of Helsinki.

We assisted a prominent family-owned company in the incorporation of their business. Our clients appreciated the ability to discuss various possibilities with us, after which we conducted a detailed analysis of the options that seemed most viable. There were various factors to consider, ranging from corporate governance to international taxation, due to which the most attractive options from a Finnish tax perspective turned out to be less feasible in the overall analysis.
