Petra Hanselmann is knowledgeable across a spread of issues, such as private equity transactions, pre-transaction restructurings, and joint ventures, with Severin Roelli being recommended for his expertise in M&A transactions with particular regard to public takeovers. Pascal Richard and Beat Schwarz are other names to note in the group, both capable of acting on a domestic and international scale.
