Tensions have reached a boiling point at Corona's hospital after physicians held an emergency meeting to ask the top administrator to resign because of what they call antagonistic management practices. Roughly 50 physicians at Corona Regional Medical Center voted Thursday, Sept. 6, in support of a no-confidence vote and a request for the immediate resignation of Chief Executive Officer Kevan Metcalfe. Hospital spokeswoman Linda Pearson said Monday, Sept. 10, that the medical center does not comment on internal matters about its staff.
