Dr. Highman and the surgical team pride themselves in their friendly, efficient and prompt evaluation and treatment of all patients.

Glenn Medical Center follows the National Healthcare Safety Network (NHSN) procedures identified by state law for ongoing surveillance of surgical site infections. They believe that infections can be reduced through the identification and prevention of risk factors. Glenn Medical Center evaluates procedures, policies and practices, looking for preventable risk factors, when infection trends are identified.
