Michael Hart joined a Carlyle Group business development company, Carlyle GMS Finance, as president and managing director, a news release said.
Mr. Hart replaces Mitch Petrick, who remains chairman, an SEC filing by Carlyle GMS Finance showed.
Mr. Hart will lead Carlyle GMS Finance's day-to-day activities. The company makes debt investments in U.S. middle-market companies.
Spokesman Randall Whitestone declined to comment.
Mr. Hart had been managing director and co-head of the U.S. advisory practice within the financial markets advisory group at BlackRock Solutions. “As a matter of company policy, we do not comment on personnel changes,” BlackRock spokesman Farrell Denby said in an e-mail.
