NAME: L. Mark N. Greene

TITLE: CEO, FICO Inc., the company that calculates consumer credit scores.

CAREER: Began his career in 1982 as an economist and researcher for the Federal Reserve Board. After stints at Technology Solutions Company, Berkeley Investment Technologies, and Citicorp, he spent 12 years at IBM, including time as a vice president in its Financial Services division and as a general manager of its banking unit. Named CEO of Minneapolis-based FICO, formerly known as Fair Isaac Corp., in February 2007.

AGE: 55

MAJOR CONCERN: Greene wants to make sure consumers understand their credit scores and know what they can do to improve them. He's concerned about "unsavory credit repair organizations" duping people with shady schemes, and those who offer so-called free services that end up signing consumers to unexpected contracts. "I'm not a big fan of the guy who plays the banjo and sings poorly on TV," he said.
