NEW YORK, NY.- Christie's announced the promotion of Kimberly Miller to Global Managing Director for Luxury. This appointment follows an exceptional year for Christie's Luxury.

Overall, the Luxury category realized $795M, marking 17% growth from the previous year.

Kimberly Miller previously served as Regional Managing Director for Luxury Americas, where she led business strategy, sales expansion, and financial performance across the Jewelry, Watches, Wine, and Handbags departments.

Koch last year.

Prior to joining Luxury, Kimberly held senior specialist and management roles in 20th Century Design having begun her career in the Wine Department at Christie's in 2010.
