David Marchick is leaving his managing director and global head of external affairs post at Carlyle Group at the end of the year.
The 52-year-old executive will take a senior advisor post at the investment firm as it completes the transition to a new management team.
Glenn Youngkin and Kewsong Lee assumed Co-CEO positions in January.
Marchick, who joined Carlyle in 2007, eventually plans to move into the non-profit sector, according to the Washington Post.
At Carlyle, he helped plot the company's shift from a privately held firm to a public company traded on the NASDAQ.
Prior to joining the DC-based firm, Marchick handled international affairs at law firm Covington & Burlington and did a seven-year stint in the Clinton administration at the White House, Office of the US Trade Representative and Depts. of Commerce and State.
Carlyle has $210B in assets under management.
