(Reuters) - Goldman Sachs Group Inc GS.N named Dan Dees as its new investment-banking co-chief, Bloomberg reported on Wednesday, citing people with knowledge of the matter.

Dees will head the bank’s most profitable unit along with Gregg Lemkau and Marc Nachmann, according to the report.

Goldman announced its biggest management shakeup last week since naming David Solomon as Chief Executive Officer Lloyd Blankfein’s successor.

Last week, the bank said long-term insider John Waldron will take over as president and chief operating officer. Waldron, who currently runs investment banking, will become Solomon’s No.2 when he takes the CEO role in October.

Goldman did not immediately respond to a request for comment.
