Katie Vander Zanden, who previously led both markets, is now chief administrative officer of BMO Private Bank. This is a newly-created role in which Zanden assumes overall responsibility for BMO Private Bank's compliance, audit, initiatives management and administrative functions. She will also lead initiatives designed to improve the overall client experience, the bank said.

“Adding an extra leadership position reflects our outlook for the prospects of growth in both marketplaces, and we intend to expand our customer base considerably in the coming years,” said Zach Lazar, president for Illinois and Florida.  

Zanden has over 33 years of financial services experience and has been with BMO since 1996. In her most recent role, she was responsible for private banking operations in both Hinsdale and Naperville.
