A One of a Kind Doctors Group

Associates: Drs Allan D. Lieberman, William J. Wiers and Bettina Herbert

The Center for Occupational and Environmental Medicine is one of the few resources for the practice of Environmental Medicine in the entire Southeast. We have been providing comprehensive treatment for pediatric and adult patients for 33 years.   Since the pioneer days of Louis Pasteur 140 years ago, medicine has been fixated on the role of microorganisms as the cause of disease.  Now, as we enter the 21st century, we are more aware of the air we breathe, the foods we eat, and the chemicals that pollute our air, food and water as a cause of disease.  Included in these environmental factors are also all forms of radiation.

“The Center” specializes in Environmental Medicine, a board certified and evidence-based branch of medicine formed over 50 years ago. This is one of the most exciting specialties in medicine, encompassing allergy/immunology, toxicology, and nutrition. Environmental Medicine focuses on finding the causes of an illness rather than just treating the effects. Our medical practice is concerned with the whole person—not only the body, but also the mind and spirit. The practice is scientifically evidence-based while focusing on diet, lifestyle, and preventive measures. We know that a healthy body is better able to heal itself and also to defend itself against disease. We see ourselves as your partner in the healing process, educating you to make informed decisions and take charge of your health care choices.
