Deb Hordon Ph.D., is Founder/CEO of ToxiMapp, an environmental-intelligence platform that helps individuals and professionals know which toxicants are present in the air, water, and soil (and where they are located) near any address in America.

Deb has a Ph.D. in quantitative sociology from Columbia University and worked as a researcher at Harvard Medical School's Department of Healthcare Policy. She has also been an organizational and leadership consultant and lived and worked all over the world (Lima, Istanbul, Milan, London, Dublin) for many years.
