Shortly after starting his new job with the Virginia Department of Health as a public health nurse supervisor last February, 30-year-old Nathan Cass found himself vaulting from new employee orientation classes to the regionâs COVID-19 hotline coordinator. âI was in orientation as the Health Department was just starting to ramp up and shift focus in anticipation of the coronavirus pandemic,â said Cass, whose office is located in the Stafford County Government Center. Nathan Cass explains the challenges of running a COVID-19 vaccination clinic. Cass, a registered nurse, had just transitioned from a job as a medical facility inspector. Prior to that, he worked for the Health Department inspecting nursing homes and other treatment facilities to ensure they were complying with federal insurance requirements. He also spent a year at Stafford Hospital and worked at Bon Secours St. Francis Medical Center in Midlothian.
