Introduction
Experience
Professional experience in ozone system development, ozone applications, ozone consulting (including applications engineering), and project management, spanning a comprehensive range of commercial and residential industries. These include, but are not limited to, aquatics, food safety applications (commercial and food service), wineries, pharmaceutical and industrial uses. Highly experienced and very adept with regulatory compliance responsibilities for the use of ozone, while staying up-to date with emerging governmental compliance developments. Maintaining an ongoing focus for developing parameters for ozone efficacy and worker/environmental safety for a broad range of applications. Authored regulatory code for numerous ozone applications, interfaced with government agencies to assist in their understanding of ozone’s efficacy and safety, and a working member of multiple public health standards writing committees as their chosen ozone expert. Developed protocols for efficacy testing of ozone in several applications, including those for surface sanitation with aqueous ozone as well as water and product sanitation with species-specific pathogens, with accredited third-party testing agencies as well as Universities across the United States.
