As a dispute resolution specialist, I have in-depth experience of arbitration, litigation and alternative dispute resolution spanning over three decades.

In 2020, having been a partner at Roschier Attorneys Ltd for twenty years, I set up my own practice dedicated to serving as independent arbitrator and mediator in international and domestic disputes. In addition, I provide expert opinions for arbitration or court proceedings in Finland and for the purposes of legal risk management.

During my career I have been involved in more than 200 major disputes as counsel or arbitrator. The matters in question have included several landmark and high-value cases relating to energy, construction, shareholders' agreements, product liability, securities law and personal liability of directors, as well as a wide variety of contractual matters involving among others M&A, private equity, distribution, IT and telecom.

I have participated in the development of alternative dispute resolution mechanisms in Finland and internationally and served on the Board of Finland Arbitration Institute and on the Mediation Board of the Finnish Bar Association. Currently I am the member nominated by Finland in the ICC International Court of Arbitration. My working languages are Finnish, English, Swedish, French and German.



I serve as an independent arbitrator in international and domestic disputes, both as a sole or presiding arbitrator and as a party-nominated arbitrator. My arbitration experience as counsel and arbitrator covers arbitration proceedings under a number of different laws and rules, including the ICC, the Finland Arbitration Institute (FAI), the Stockholm Chamber of Commerce, the Swiss Rules and the UNCITRAL Rules and includes expedited proceedings and statutory arbitrations (squeeze-outs of minority shares in listed companies).

Before being nominated as member in the ICC International Court of Arbitration in 2018, I served on the Board of the FAI for five years in 2013-2018. I have been actively involved in the work of the ICC Commission on Arbitration and ADR since the 2004 and he headed the Finnish delegation with the ICC Commission between 2012 and 2018. Over the years I have held several other positions of trust and participated in working groups in the area of international arbitration. I have written numerous articles and book chapters on arbitration and alternative dispute resolution, and my comparative study on the current Finnish Arbitration Act was published in Paris in 1997. I have been a frequent speaker in conferences and seminars and have been on the faculty of the Finnish Arbitration Academy as of its inception in 2015.


Mediation is an efficient way of resolving disputes in a less adversarial setting quickly and confidentially. Mediation is in essence a structured negotiation process in which an independent third party, the mediator, assists the parties to reach an amicable settlement to their dispute. Mediation may be conducted as an ad hoc arrangement or under specific rules, such as the ICC Mediation Rules, the FAI Mediation Rules or the Mediation Rules of the Finnish Bar Association.

I have had a central role in the introduction and promotion of facilitative mediation as an alternative for the settlement of commercial disputes in Finland. I was one of the members of a small working group set up by the Finnish Bar Association that prepared the Mediation Rules of the Finnish Bar Association in 1998. I have had key responsibilities in the training of mediators at basic and advanced level ever since. I was a long-time member and Chair of the Mediation Board of the Finnish Bar Association. I was  originally trained in mediation by the Harvard Team and have polished my skills as a mediator in numerous subsequent trainings, including training for mediator trainers by the Centre for Effective Dispute Resolution (CEDR). I serve as mediator in international and domestic disputes. My mediation experience covers both serving as the mediator in contractual and IP disputes and acting as counsel in mediations, including ICC ADR proceedings.

Expert Opinions

In complex international arbitrations and in cross-border court proceedings there is sometimes a need for legal expertise on issues of substantive and procedural law. Independent legal expertise may also be useful for the purposes of legal risk management and early case evaluation in the case of a pending or threatening dispute.

My relevant experience in this area covers a wide variety legal risk assessments and assisting clients faced with a threat of civil, criminal or administrative proceedings in Finland and abroad in matters pertaining to many different areas, such as securities and company law, disagreements with long-time partners, compliance issues and professional malpractice. Over the years I have also provided expert testimony for court proceedings in several different jurisdictions.
