JPMorgan Chase & Co. said Thursday it has hired Jim Woolery, an M&A partner with law firm Cravath, Swaine & Moore, to help lead its North America M&A division together with Chris Ventresca.

Former global M&A leader Jimmy Elliott, a 14-year veteran of the New York-based investment bank, is being promoted to the position of global chairman of mergers and acquisitions. He will work with the firm's most important clients on strategic transactions.

The bank also is revamping its health care practice, naming Jeff Stutewill as head of its North America Healthcare group. Stute has been the primary mergers and acquisitions partner and a member of the firm's healthcare practice for 17 years. Robbie Huffines will become vice chairman of investment banking.
