Martin Ventures-backed physician network startup Wellvana Health has refreshed its C-suite, which includes rotating CEO Worthe Holt to serve as chief medical officer and bringing in three outside executives.

Former Anthem executive Jay Meyers takes over as chief executive less than a year after Holt’s original appointment. Sunil Cardozo has also been named chief operations and information officer and Readus Smith will serve as chief managed care officer.
