About Us

SAFER’s mission is to help businesses, organizations, and campuses re-open and stay open. Our SAFER Card™ system offers cost-effective, rapid screening for anosmia/hyposmia, one of the earliest and most reliable symptoms of COVID-19.

Dr. Sarah Davis, M.D.

Sarah Davis, M.D., founder of SAFER Diagnostics™, is a doctor and an entrepreneur. She is an ABMS certified family medicine physician who has been practicing for over two decades.

Dr. Davis is a lifelong innovator in care and treatment, introducing the very first concierge medical practice in North Texas.

When Dr. Davis’ own daughter contracted COVID-19 as a summer camp counselor, Dr. Davis noticed a decreased sense of smell that with objective testing was much worse than she even realized. She then performed a community COVID-19 study, leading to the invention of the SAFER Card™ and SAFER Campus™ system.
