Exposure to beryllium, coal dust, asbestos, latex or any work-related substances can cause serious breathing issues.

If this has happened to you, you can trust your care to the occupational medicine experts at National Jewish Health in Denver, Colorado, the leading respiratory hospital in the nation.

Our multidisciplinary team provides comprehensive diagnosis and treatment to patients with a broad range of work-related lung diseases. We also work with employers, unions, industry, government and others to provide occupational health and safety programs to reduce and prevent work-related lung diseases such as asthma, COPD and bronchiolitis.

Our doctors are researchers, too, so you have access to the latest clinical trials and most effective treatments.
