Contact details

I advise our clients in assignments related to international construction and projects. Prior to joining Castrén & Snellman, I worked for a federation focusing on real estate brokerage and on issues related to both residential and real property law. In addition to this, I have worked in the Government of Åland and in another law firm.

In my current role, I am particularly inspired by the wide range of assignments in various areas of law. I enjoy an enhancing work environment that combines an international mindset with challenging assignments and an efficient work flow.

I hold a Master of Laws degree from the University of Eastern Finland. During my studies, I also studied at the Uppsala University in Sweden and participated in the Willem C. Vis International Commercial Arbitration Moot which focuses on international commercial law and arbitration for resolution of international business disputes.
