The job of public health professionals at the Knox County Health Department is to promote health, prevent disease and injury, and to maintain and improve a healthy environment for the protection of all residents of Knox County. We assess, we assure, we promote, we prevent, we protect.... all to help extend the benefits this world has to offer to each of those we serve. It's an honor, a responsibility and some days, a tough job. And we do it gladly - because we are public health.
