Blue Shield of California’s longtime chairman and chief executive, Bruce Bodaken, will retire at year’s end, punctuating a career marked by praise for his early support of universal health coverage and criticism of his company’s repeated rate hikes. Bodaken, 60, will leave at the end of December, and Paul Markovich, 45, currently chief operating officer at the nonprofit health insurer, will take over as CEO. The San Francisco company’s 10-member board will elect a new, independent chairman this year according to a report in the Los Angeles Times.
