Building a Better Way to Achieve Our Common Goal
On Site Medical is an occupational health provider with more than 30 years of experience—and we’ve seen the pitfalls of industrial medicine firsthand: skyrocketing costs, lost time and even fraud, often brought on by excessive care. So we set out to create a new model—on-site clinics, mobile medical units and on-demand mobile first aid that prioritizes the health of employees and the bottom line of their employers.
Reduce the Impact of Workplace Injuries or Your Money Back.
We stand behind our occupational health model. If we don’t help reduce the impact of workplace injuries on your people and your books, you don’t pay.
How We Work Differently.
Clinicians, operators and builders who set out to fix occupational health from the inside.
