Heading up enterprise risk management (ERM) is hard enough at any company. But add to that the pressure of working for a company that essentially handles risk management for other companies, and you get a sense of the challenge facing Jeff Lawrence.

As vice president and treasurer of Boston-based Iron Mountain Inc., the 54-year-old Lawrence handles contracts, banking and credit relationships and internal audit at the company, which is a leading provider of storage and backup of the mission-critical records of tens of thousands of corporations. A year ago, however, his role was dramatically expanded when the company chose him to head its enterprise risk management committee. "It made sense," says Lawrence. "In fact, I'm actually surprised that it's not typical to have treasurers taking on this role. I think it's an ideal fit."
