The principal of Regna Toxicology is Joseph Regna, M.D., M.P.H., medical toxicologist and environmental/occupational health specialist.

My expertise is medical toxicology and environmental and occupational health.  I have worked with attorneys, consulting companies, and non-profit organizations on projects that have involved assessing the health effects from exposure to toxic substances, including chlorinated hydrocarbons, solvents, pesticides, toxic gases, particulate dusts, and metals.  Thoughout this work, I have endeavored not only to be a source of objective analysis, but also to base my expert judgments on sound science.
