Dan’s clients turn to him for advice on matters related to process safety management (PSM), occupational safety, environmental and transportation issues in petroleum, chemical and industrial manufacturing and mining. As a chemical engineer, former chemical plant EHS manager and in-house counsel, he possesses a wide-ranging perspective on matters relating to strategic operational efficiencies and corporate compliance.

He was senior counsel and vice president of a major energy company and has provided legal support for refineries, mines, gas operations, foundries, manufacturing facilities and distribution centers in the United States, Canada, China, Europe and Mexico.
