Contact details

I advise our clients in assignments related to domestic and cross-border mergers and acquisitions. I specialise in corporate law, corporate governance and capital markets transactions.

I joined Castrén & Snellman after graduating from the University of Helsinki in 2019. During my studies, I worked in several business law firms and in a major publicly traded technology company. Prior to entering the legal industry, I gained experience in financial communications and investor relations at an international public relations company.

In addition to my law degree, I hold a Master of Science (Economics & Business Administration) degree from Aalto University. As part of my M.Sc. studies, I studied business administration and competition law at Solvay Brussels School of Economics and Management at Université libre de Bruxelles.
