This press release is from the Rood Center:
Beginning January 1, 2021, Dr. Scott Kellermann will be joining the County of Nevada as Public Health Officer. While Dr. Kellermann will begin his role as Public Health Officer on the first, his contract will formally come before the Nevada County Board of Supervisors at their January 12th meeting to officially appoint him to the vital public health role.
Dr. Kellermann received his medical degree from Tulane University School of Medicine with a Master’s in Public Health and Master’s in Tropical Medicine. He was an intern at USC/LA County Hospital and a Family Practice resident at UCLA. Currently, Dr. Kellermann is an adjunct professor at the University of San Francisco and an assistant clinical professor at California Northstate University College of Medicine in Elk Grove, California. He is a Senior Consultant for the Centers for Research in Emerging Infectious Diseases (CREID), through the National Institute of Health and UC Davis. CREID research will attempt to identify novel viruses and prevent future pandemics.
“I look forward to engaging in public health in Nevada County, particularly with an immunization campaign to end the current COVID-19 pandemic,” said incoming Public Health Officer Dr. Kellermann. “I look forward to giving back to Nevada County the kindness and generosity that has been shown to me.”
“We are extremely grateful to Dr. Richard Johnson who has served with us as our Interim Health Officer since June. His experience as a local Health Officer and his vast experience in emergency preparedness and response served our community very well,” said Nevada County Public Health Director Jill Blake. “Dr. Kellermann’s deep community roots and breadth of experience as an MD will also serve us well. We look forward to this next chapter bringing Dr. Kellermann on as our Health Officer alongside Deputy Health Officer Dr. Glennah Trochet as we work to provide a safe and equitable COVID vaccination process to Nevada County residents.”

As I half-joked to Shannon, nobody can accuse Dr. K of being “the man.”
