He’s advised on a range of complex transactions including cross-border M&A, private equity investments, product sales and acquisitions and joint ventures involving multi-jurisdictional coordination, regulatory navigation and tailored structuring.
Global Head of Corporate Sarah Jones said, “We are delighted for Peter to join our global team in the US. His appointment underscores the growing momentum in healthcare and life sciences within the M&A and private equity landscape, as investors seek to capitalize on strategic opportunities amid evolving regulatory frameworks. With deep understanding of the sector combined with his significant experience in cross-border transactions, Peter brings invaluable insight that will benefit both our domestic and international clients.”

I am excited to welcome him to the team.”
