AlTi Global Names Patrick Keenan CFO as Harrington Exits
Michael Harrington will retire as chief financial officer of AlTi Global, the Nasdaq-listed wealth manager with about $90 billion in assets, at the end of this month. The company has appointed Patrick Keenan, the company’s 36-year-old chief accounting officer, as his successor in a “planned transition,” according to a regulatory filing.
Keenan will report to President and Chief Operating Officer Kevin Moran.
He has served as chief accounting officer since 2024 and principal accounting officer since 2025. He joined in 2022 as director, global lead of accounting policy and SEC reporting. Prior to joining the firm, he served in finance and accounting positions at Aflac Global Investments.
Harrington joined AlTi Global in early 2025. Prior to that, he served as CFO of Republic First Bancorp. Before that, he was banker-in-residence at Jacobs Asset Management’s partnership with FINTOP.
This follows news in March that Michael Tiedemann, the CEO and founding partner of the firm, stepped down from the leadership role, a little under three years after taking the firm public.
Tiedemann was replaced on an interim basis by Nancy Curtin, the firm’s global chief investment officer and member of the leadership team. Tiedemann is serving in an advisory capacity to “support the transition,” the company said.
In 2023, Tiedemann merged his New York-based RIA and alternative asset management firms, Tiedemann Group and TIG Advisors, with London-based asset manager, merchant bank and global multi-family office Alvarium Investments and took them public via a special purpose acquisition company. Since then, the firm has made numerous acquisitions in the U.S. and Europe, including a deal last March for a $15 billion multi-family office headquartered in Hamburg, Germany.
