Mike helps clients solve complex challenges arising from land, water, and air pollution.

Environmental lawyer Michael Dunning has particular experience in matters involving contaminated sites (aka "dirty dirt"). He previously served for more than a decade as an assistant attorney general for the state of Washington and acted as lead counsel on some of the state's most challenging and complicated contaminated sites and cases.

As the former section chief of the Washington Attorney General's Hazardous Waste Cleanup section, Mike led a team supporting the state's Department of Ecology on all aspects of contaminated sites. His insider's view informs his innovative solutions for business, local government, and nonprofit clients in litigation, transactional, and permitting matters. Mike's depth of knowledge of Washington's superfund law, the Model Toxics Control Act (MTCA), includes experience as an expert witness.
