A Kerry man has been appointed head of Matheson’s US office.
Mark O’Sullivan, who was born in Valentia, will lead the legal firm’s new premises in San Francisco.
Mr O’Sullivan first moved to the California office in 2007, at a time of significant volatility in the Irish and global economy.
He currently advises international companies on establishing operations and doing business in Ireland, including international tax planning, cross-border reorganisations and inward investing and structuring.
Since opening the first European legal practice in Silicon Valley in 1996, Matheson has worked closely with some of the world’s largest tech multinationals, advising 7 of the top 10 global technology brands.
