HOUSTON -

METRO's president and CEO George Greanias will step down from his post at the end of the year.

Greanias announced his resignation on Monday. He has been at the top of the transit agency for two and a half years.

METRO Chairman Gilbert Garcia applauded Greanias' accomplishments and looks forward to finding the next leader for the agency. 

"George has done an outstanding job of turning things around at METRO and focusing on openness and transparency. We look forward to a smooth transition," Garcia said. "The Board will meet on Thursday, Dec. 20, to discuss options for selecting an interim CEO and, ultimately, finding a new president and CEO."

Greanias is a former Houston city councilmember, city controller and management consultant.  He expressed great appreciation for the hard work of METRO's 3,400 employees and the community’s support for METRO. 

"One of my career highlights now includes my time at METRO and working with a talented group of people who work every day to provide the best transit services for this region," Greanias said.

Greanias' tenure did have some controversy.

In July 2011, Greanias was suspended for looking at porn through the company's Internet system.

METRO officials said an investigation revealed that George Greanias accessed more than a dozen adult-oriented sites of a sexual nature on 14 days from Feb. 9 to July 1, 2011. Agency officials said Greanias was on his own computer, but was logged onto the agency's Wi-Fi network. Greanias was suspended for one week without pay.
