The sale of Steward Health Care's physician network to the Rural Healthcare Group has been finalized, the buyer announced Thursday along with a new name for the consolidated company: Revere Medical. The Tennessee-based affiliate of New York-based private equity firm Kinderhook Industries agreed in August to buy Stewardship Health for $245 million in cash. Revere Medical said Thursday that the transaction had closed and that its new name is meant to reflect the "path to building the country's most revered provider organization."
