  1. Private M&A

I specialise in mergers and acquisitions and have been involved in both domestic and international transactions in the past years. In addition, I have several years of experience advising clients on their corporate matters.

I started working in Castrén & Snellman’s transaction team in April 2021 and, prior to joining C&S, I worked at another Finnish law firm for over ten years, first as a legal trainee and later as an associate after my graduation. During my previous employment, I was also on secondment at a client company, where I gained experience as in-house counsel. In addition, I worked as a legal trainee with two international companies prior to my graduation.

As a transaction lawyer, I enjoy the hecticness and project nature of transactions. I see myself as a solution-oriented and efficient team player. I especially enjoy working in an expert organisation environment and enjoy the challenges that various transactions bring to my table daily.

Yanhuan Zhou’s tireless dedication and commitment was very much appreciated and made a significant difference on our recent deal.
