Hagedorn will take on the role of senior portfolio manager for Millennium’s credit unit in New York later this year, some of the people said, requesting anonymity speaking about a private matter.
Spokespeople for Diameter and Millennium declined to comment.
Previously based in London, Hagedorn joined Diameter in early 2023.
Hagedorn isn’t the first senior hire that Millennium’s credit unit has made from Diameter.
