Lead Antimicrobial Consultants
Connie Welch: An expert in environmental laws and regulations, Connie’s background includes a 17-year distinguished career within the US EPA Office of Pesticide Programs (OPP), where she held prominent leadership positions dealing with conventional pesticides, antimicrobial pesticides, and inert ingredients. In her role as Chief of Regulatory Management Branch II in the Antimicrobials Division of OPP, Connie developed a strong interactive working relationship with other offices within the EPA (i.e., the Office of Pollution Prevention and Toxics, the Office of Drinking Water, and the Office of Solid Waste) and other federal agencies (the Food and Drug Administration, the Consumer Products Safety Commission, and the USDA). Because of Connie’s extensive EPA career and over 20 years of experience as a leading regulatory consultant to industry, she is ideally suited to providing clients with a wealth of pesticide knowledge and expertise.
