Dan has dedicated his career to protecting the environment and ensuring that people are afforded a safe and healthful place to work.

Dan’s work includes the representation of governmental entities, individual consumers, and corporate clients—all with one primary goal in mind: ensuring the protection of human health and the environment. His stewardship ensures not only that polluters be held responsible for contamination and clean-up, but that corporate entities understand their responsibilities under state and federal environmental laws. As a result of Dan’s advocacy in counseling clients on compliance, his corporate clients lead their respective industries in environmental stewardship efforts under a number of rules and regulations including the Clean Water Act (CWA), the Clean Air Act (CAA), the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the Emergency Planning and Community Right-to-Know Act (EPCRA), and the Resource Conservation and Recovery Act (RCRA).

Dan assists corporate entities, governmental agencies, and the public with ensuring that companies that have contaminated the environment and violated environmental regulations take responsibility for their actions and remediate the harm they have caused through contribution and cost recovery actions, common law claims, citizen suits, enforcement actions, and proper due diligence and contract negotiation. Most recently, Dan joined a team of other DiCello Levitt attorneys and appointed Special Assistant Attorneys General to file lawsuits against polluters in the State of Michigan, seeking to hold them responsible for contaminating the environment with poly- and perfluoroalkyl chemicals, sometimes referred to as “forever chemicals.” Cases involving these chemicals will have wide-reaching implications for state governments and their residents.

In addition to his environmental work, Dan frequently counsels clients on developing and maintaining state-of-the-art safety and health programs that ensure all employees enjoy safe and healthful workplaces, and works closely with both his clients and the Occupational Safety and Health Administration (OSHA) to enhance employee safety and health well beyond OSHA’s minimum requirements.
