Drysdale comes to NSSGA from Rimkus Consulting Group, Inc., Houston, a provider of forensic consulting services, where he was division manager. He managed and assisted projects and investigators evaluating workplace and environmental exposures related to chemical, physical and biological contaminants. Drysdale provided litigation support as an expert witness for toxic tort claims, and frequently testified in state and federal courts.

Prior to his time at Rimkus, Drysdale worked in Houston for Brown & Root, Inc., and its parent company Halliburton, where he was coordinator for global health, safety and environment standards and policy and, prior to that, as manager of industrial hygiene.

Drysdale began his industrial hygiene career with Vulcan Materials Co., in Birmingham, Ala. He holds bachelor's and master's degrees in biological sciences and a master's degree in public health. Drysdale is a certified industrial hygienist with more than 30 years’ experience conducting health, safety and environmental investigations, with published research in environmental toxicology.

"Dale is a versatile leader experienced in managing corporate health, safety and environment issues. He brings to NSSGA experience in working with industrial hygiene and occupational health programs and in providing comments to OSHA, MSHA and EPA during formal rulemaking processes," said NSSGA President and CEO Joy Wilson. "He will be a great addition to our strong ESH Division staff."
