Citi Private Bank has hired Alexander “Lex” Zaharoff as managing director and head of the North America investment lab.

Zaharoff, who is scheduled to join Citi on July 1, will be based in Citi’s New York office and report to North America Head of Investments Steve Bodurtha.

Zaharoff joins Citi after serving as managing director at private investment firm Carleon Capital Partners, which focuses on ultra high net worth families. Prior to that, Zaharoff served as managing director and head of investment strategies in the Americas for HSBC Private Bank.

Zaharoff’s appointment comes as Citi Private Bank also hired two other managing directors this month. They include Patricia McDermott, who will serve as managing director and head of Connecticut and Westchester, and Christopher Adams, who will serve as managing director of investment finance.

Citi Private Bank targets ultra high net worth clients with $25 million or more in investable assets.
