An OhioHealth medical directorship is like having a corporate medical advisor on your team, who is focused on decreasing work-related injuries, improving employee wellness and reducing time away from the job. Our experts design customized occupational health and medical management programs that address the health risks and common conditions your employees face. They also provide medical oversight for emergency response protocols.
