George Postolos announced Monday that he has resigned as president and chief executive officer of the Houston Astros.
Postolos had been with the Astros since November 2011. He spearheaded several changes within the organization, including the Astros' overall rebranding process, including new team uniforms, colors and logos.
He will be returning to his consulting practice, advising investors on acquisitions and strategy in major league sports.
"I am very proud of what Jim (Crane) accomplished with my help - acquiring a major league franchise with a strong and diverse ownership group, developing and implementing a good plan for the team's future, and assembling a first rate management team," Postolos said.
Postolos joined the Houston Rockets in 1998 as the team’s chief operating officer. In 2002, he was named president and CEO of the Rockets before working with the Astros.
