US: Titan Group has announced that after 20 years at the helm of Titan America, Aris Papadopoulos will retire from the position of CEO, effective 1 August 2014. According to a release, he will become Executive Chairman of ST Equipment & Technologies (STET), reporting to the Group CEO and also serve as an advisor.

The company noted that, commencing with a 1994 joint venture with Roanoke Cement, Papadopoulos led Titan America through a growth trajectory that included the acquisition of Tarmac America and Separation Technologies, modernising the company's two cement plants, numerous operational expansions and multiple concrete acquisitions.

"During Aris' tenure, Titan America grew from a cement joint-venture in Roanoke, Virginia, to the pre-eminent East Coast construction materials producer," said Dimitri Papalexopoulos, CEO of Titan Group. "Aris, more than anyone else, has shaped Titan America over two decades."

Bill Zarkalis, Group CFO since 2010, will succeed Papadopoulos. Zarkalis joined the Group in 2008 as Director of Business Development. He previously held executive positions at Dow Chemical. As CEO-designate, he will work closely with Papadopoulos to ensure a smooth transition. Michael Colakides will become Group CFO, effective 16 May 2014. Colakides recently returned to the Group as Senior Strategy Advisor after more than a decade in several banking industry executive roles.
