Raniero D'Aversa has joined the firm as a partner to head the New York creditors' rights and bankruptcy practice.
Mark Fennessy, a partner in the firm's London creditors' rights and bankruptcy practice, said: "We are very excited about the continued expansion in the firm's bankruptcy, restructuring and creditor rights' capabilities with Raniero's hire.
"This expansion reflects the firm's ambition to have one of the leading groups in this space within the next few years."
D'Aversa's practice focuses on bankruptcies, out-of-court restructurings and creditors' rights controversies, acting for secured lenders and bank groups, investment banks, hedge funds and other financial institution creditors.
D'Aversa's hire is the latest in a recruitment drive that began when Fennessy joined the firm from Hunton & Williams in May (as reported by The Lawyer 6 May).
Fennessy left Hunton after two years, having joined the firm from Clyde & Co, claiming Orrick had a bigger platform.
