William Lee has resigned as senior vice president and chief investment officer of New York-Presbyterian Hospital, a hospital spokeswoman confirmed.
He left "to pursue the next chapter in his accomplished career," the spokeswoman wrote in an email.
"Since 2016, his effective financial stewardship has helped strengthen NYP's ability to achieve our mission to provide exceptional care for all of our patients and the communities we serve, and we wish him continued success," she wrote.
The spokeswoman declined to comment on who will succeed Mr. Lee or whether the hospital will conduct a search for a permanent replacement.
According to the website of the Rockefeller Brothers Fund, which lists Mr. Lee as a trustee, he was responsible at the hospital for its $9.5 billion investment program, "including endowment, retirement and current assets, and managing the office of investments team responsible for all of NYP's investment assets."
