Avison Young's top U.S. executive has left the company after less than two years, and the firm has appointed a new president.

Avison Young announced Tuesday it promoted Harry Klaff to the role of U.S. president. Based in D.C., Klaff joined the firm in October 2020 from JLL and previously served as president of clients.

As president, Klaff will oversee Avison Young's U.S. markets, work to develop new client relationships and lead its 2,000-plus employees in the country, according to a press release. Avison Young Chairman and CEO Mark Rose said in a statement that Klaff has been an "integral part" of the company since his hiring.

“He has made significant strides in bolstering our reach and offerings in the occupier, owner, and investor spaces, and his depth of experience — specifically in client-facing roles — will allow him to provide invaluable support to our teams as we work to continue creating real value for clients," Rose said.

Klaff succeeds Juan Bueno, who the release said "is leaving the firm for a new opportunity," but it didn't go into more detail. Bueno's LinkedIn page doesn't list a new employer. He joined the firm in September 2021 after spending five years as a vice president at Home Depot and 10 years at McKinsey & Co., according to his LinkedIn page.

Bueno spoke to Bisnow in November about the firm's efforts to increase its diversity. Avison Young added two people of color and three women to its executive committee in 2022.
