About Me

As an occupational medicine physician, I specialize in CBRNE (chemical, biological, radiological, nuclear and explosives) terrorism, all-hazards preparedness, tactical medicine and surety medicine. I’m the director of Occupational Medicine and Employee Health Services for The Ohio State University Wexner Medical Center. I enjoy treating the physical and mental health of specific populations, such as military and law enforcement personnel, because they often deal with dangerous situations to keep us safe every day.

I’m also an associate professor at the Ohio State College of Medicine. I enjoy teaching and have taught for many years at Ohio State as well as with the U.S. Army Public Health Center. Currently, I teach medical students, residents and fellows about CBRNE topics through the Emergency Department. In addition, I have published articles in medical journals and developed training programs for occupational medicine residents and U.S. Army physicians around the topic of CBRNE toxicology.

By providing medical consultation, services and expertise in occupational medicine at the Bechtel Blue Grass Chemical Agent-Destruction Pilot Plant, I have directly influenced oversight requirements for many workplaces under regulatory agencies such as the U.S. Army, Department of Energy and Department of Labor.

I have also had a tremendous impact on best practices for work-related injuries that stem from cognitive impairing medications and medical conditions through my involvement with the Kentucky Occupational and Environmental Medicine Association and the American College of Occupational and Environmental Medicine. These organizations have allowed me to collaborate in Occupational and Environmental Medicine (OEM) initiatives at all levels, in addition to sharing knowledge with colleagues at regional and national conferences.

When I’m not at work, I love spending time with my family and exploring nature (including hiking trails).

Consulting and Related Relationships

At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.

As of 11/01/2020, Dr. Greer has reported no relationships with companies or entities.
