Dr. Birkholz conducted and managed human biomonitoring studies since the early 2000” s providing services to industry, government (Alberta Health), academia (Canada and abroad) as well as the Centres for Disease control. He assisted physicians and academics in studying the relationship between exposure to chemicals and chronic illness.

Chronic illness is debilitating our health care system resulting in frustrated patients and physicians and spiraling health care costs. A recent workshop organized by the National Institute of Health, Bethesda, Maryland, emphasized the need for more collaboration on the health effects of endocrine disrupting chemicals and the need for more medical intervention options.
