Kaiser Permanente promotes Tyson to chairman, CEO

OAKLAND, Calif. (AP) -- Health care provider Kaiser Foundation Hospitals and Health Plan said Monday that it will promote Bernard Tyson to chairman and CEO, succeeding George Halvorson, who is retiring.

Tyson is president and chief operating officer of Kaiser Permanente, a nonprofit organization that describes itself as the nation's largest integrated health-care system. Kaiser said Tyson will join the board of directors in December and will become CEO after a six-month transition period. Halvorson, who announced plans to retire in October, will remain chairman until December 2013.

Kaiser, which is based in Oakland, said Tyson has been its president and COO for two years. Halvorson has been chairman and CEO since 2002.
