Contact details

I advise our domestic and international clients on private equity, venture capital, fund-related matters and M&A.

I joined Castrén & Snellman as an Associate in January 2026. Prior to this, I gained extensive internship experience across different sides of the market. I have worked at the M&A and private equity practice of a large corporate law firm, and in the legal function governing private equity, private credit and infrastructure investments at one of the largest institutional investors in Finland. I have also worked as an investment analyst at an institutional investor focused on active and professional ownership, and at a Nordic private equity fundraising boutique, where I was part of the in-house legal team.

Having seen the market, transactions and investments from both the legal and the investor perspective, I understand what clients seek to achieve and ensure that this remains at the forefront of my work. My aim is always to deliver legal advice that serves the commercial objectives of our clients.

I hold a Master of Laws from the University of Helsinki (2025), with a focus on corporate and securities markets law, and am currently pursuing an M.Sc. in Finance at Aalto University.
