We are a multidisciplinary team focused on the detection, treatment and prevention of pulmonary diseases that are primarily a result of occupational/environmental exposures. We provide comprehensive diagnostic and therapeutic services to patients with a broad range of occupational/environmental and granulomatous lung diseases. We also work with employees, unions, industry, government and others to provide exposure assessment, medical surveillance, respirator fit programs and education to ultimately reduce and prevent occupational and environmental illnesses. Why National Jewish Health? With more than 25 years of experience, our division is recognized internationally for its comprehensive clinical, research and educational programs in occupational and environmental lung diseases. We have a number of research programs. Specifically, we define the clinical presentation of new and already known occupational and environmental lung diseases, their natural history and the exposures, as well as clinical, genetic and other risk factors and inflammatory/immunologic mechanisms that lead to these occupational/environmental and other granulomatous lung diseases.
