Psillakis has extensive international market experience to draw from.
He joined Daimler in 1992 as a management trainee with its Greek subsidiary Mercedes-Benz Hellas (MBH). He would rise through the ranks of MB Hellas, becoming general manager of passenger cars in 2001.
In 2009, Psillakis moved to Mercedes-Benz do Brasil to serve as managing director for passenger cars in South America and Vans Sales Brazil. While in Brazil, Psillakis tripled sales volume.
Five years later, Psillakis was promoted to lead Mercedes' South Korea market. As CEO of Mercedes-Benz Korea, the executive grew the business into Mercedes' 5th largest market.
Psillakis had been expected earlier this year to be appointed U.S. sales chief, but instead was installed as Canada market CEO.
Mercedes dealer board chairman Jeff Swickard expressed disappointment that an internal MBUSA exective was not appointed to the top job.
"Existing management has done a great job guiding the company through a turbulent year," said Swickard, CEO of Swickard Automotive Group.
Even so, Swickard described Psillakis as a "well respected leader" in the Mercedes organization.
"He's been leading markets that are challenging and has had significant success," the dealer said.
