EY, formerly known as Ernst & Young, has made a change within its Swiss legal services team.

EY Switzerland has hired Oliver Blum as partner and head of mergers and acquisitions in legal services. He succeeds Jvo Grundler.

Blum most recently headed the company law and M&A focus group at CMS Switzerland, where he was a partner. He was also a member of the management committee of the global private equity CMS focus group.

Based in Zurich, Blum will head up the team that provides legal advisory and support services to buyers and vendors in the M&A space. He will work closely with Ronald Sauser, who became head of M&A in transaction advisory services in January.

“As a former senior M&A partner at one of the leading law firms in Switzerland, he [Blum] will complement our broad-based M&A team exceedingly well. His extensive network and in-depth knowledge of the M&A market create a perfect basis for positioning EY at the leading edge in Switzerland, including in legal services,” said Sauser.
