Specializing in the diagnosis, treatment, and prevention of occupational and environmental diseases and exposures

Obtaining a detailed, focused medical history and performing a thorough physical examination is a critically important part of the diagnostic evaluation (“work-up”) of occupational and environmental diseases.

Dr. Craner specializes in helping highly regulated, hazardous industries such as gold mining, assay laboratory, litharge flux manufacturing, and battery recycling to protect their employees' health and achieve effective OSHA and MSHA compliance.

Medical surveillance examinations, biological monitoring, and other monitoring of workers in hazardous occupations and industries is a major focus of Dr. Craner's practice.

Visiting workplaces or homes to investigate, observe, or measure hazardous exposures is a key skill for occupational and environmental disease diagnosis, treatment, and prevention.

Lung function testing (spirometry) and methacholine challenge testing is performed to diagnose and prevent certain occupational and environmental respiratory diseases.

Occupational & Environmental Medicine skills and expertise



Accurately determining the cause of a work- or environmentally-related disease or illness and its specific association to a chemical (toxicological), biological, or physical exposure, hazard, or condition is the key to effective treatment and prevention, as well as to compensability and preserving a job, occupation, or home.



Many occupational or environmental diseases—when accurately diagnosed—can be effectively treated by removal of the identified or suspected offending substance(s) or conditions.  In some cases, temporary or permanent relocation from a job or home is necessary.  Certain diseases require medication or other medical intervention.  Others are irreversible.



For occupations with hazardous exposures, disease prevention and regulatory compliance (e.g., OSHA, MSHA) is achieved through medical surveillance, biological monitoring, exposure controls and monitoring, and training.  Statistical analysis of individual and group medical and exposure data is essential to evaluate compliance program effectiveness and areas on which to focus or improve measures to protect employees’ health.


Public Health

The Occupational and Environmental Medicine physician diagnoses and treats not only individuals, but also evaluates and prevents disease in populations (groups of people) with a common exposure, illness or disease in a workplace, industry, occupation, dwelling, or community.
