Medical Director-Best Practice - Care Management
Bernell J. Mellema M.D.

Our goals in care management involves seeking system improvements and ways to maintain and improve knowledge and information for providers and patients alike. This allows us to maintain the highest quality, with care delivered at appropriate cost and easy access with optimal patient satisfaction.

The ever-increasing rate of change in many aspects of healthcare make these goals more challenging but at the same time all the more important. Increased use of information technology is increasing ease of sharing information and applying guidelines involving the latest and best practices, as well as increasing patient safety.
