Central Florida's second-largest hospital chain, which was known in recent years as Orlando Regional Healthcare System, has announced that it has changed its name to Orlando Health. The name change for the $1.5 billion system cost approximately $300,000 and was the result of 18 months of market research and preparation, said John Hillenmeyer, the hospital system's chief executive officer. The eight facilities under Orlando Health's will retain their current names, but each will be branded as part of Orlando Health.
