Roger FrizzellCarnival Corp., the cruise operator enduring a rocky PR term over the past year and a half, has brought in a seasoned corporate communications hand  in a new top PR role after a search.

Roger Frizzell exits the chief communications officer slot at California power giant Pacific Gas and Electric Co. after a 1.5-year stint to become CCO and senior VP of corporate comms. at Miami-based Carnival, where he'll report to CEO Mickey Arison and COO Howard Frank.

Carnival, the parent company to 10 cruise lines, has endured a challenging PR run since the global crisis of the fatal grounding of the Costa Concordia in January 2012. In February, widespread – at times, minute-by-minute – coverage of the hobbled Carnival Triumph deepened the bruise on the company's image.

He earned his PR stripes in eight years at American Airlines, exiting as VP/corporate comms. and overseeing a staff of 130 PR staffers in October 2011, ahead of AA's merger with US Airways.

He was previously with Hewlett-Packard and Compaq.
