WellPoint named Joseph Swedish as the health insurer's new chief executive Tuesday, after a six month search. Swedish, 61, will take over March 25.

Since 2004, he's been president and CEO of Trinity Health, a multi-state integrated health care delivery system, which operates 47 hospitals in 10 states.

"Having spent my entire career in health care, I have a strong sense of the market in which the company operates and I am energized by the dynamic changes taking place in the industry," Swedish said in a company statement. "I'm committed to ensuring that WellPoint remains a market leader, and I look forward to working with my new colleagues to profitably grow and enhance this organization in a changing market environment."
