HPMC OMS provides a variety of services on a walk-in basis. Preliminary evaluation and treatment is provided when a worker experiences an occupational injury, exposure, or illness. We provide the care necessary to either return the workers to work or provide them relief until they can see their own medical providers. In addition, care to allow a worker to remain at work is available for non-occupational injuries and illnesses. First aid services are available from our occupational health nurses for less serious issues.
