Founded by Roslyn Stone, Zero Hour Health has spent more than three decades as the medical team behind some of the country's most demanding employers. Thousands of outbreaks contained, exam programs run, and health department calls fielded. Behind it all is a bench of physicians, epidemiologists, and public-health professionals who have seen it all before and know exactly what to do next.

We have a presence in all 50 states, Canada, Mexico, and more with medical directors on call around the clock. Think of us as a seasoned medical department, standing by whenever you need us, without the cost of building one yourself.
