Cascadia Law Group welcomes Dennis McLerran

The former EPA Region 10 Administrator and Executive Director of the Puget Sound Clean Air Agency has joined our Seattle office.

On June 1, Dennis McLerran returned to the practice of law and dispute resolution, becoming Of Counsel at Cascadia Law Group PLLC after serving seven years as the Regional Administrator for EPA Region 10 and as Executive Director of the Puget Sound Clean Air Agency. Dennis focuses his practice on environmental, climate change, land use, treaty rights and regional regulatory issues.

President Barack Obama appointed Dennis in 2010 to the post of EPA Region 10 Administrator for the states of Washington, Oregon, Idaho, and Alaska, where he served until the end of the Obama Administration in January 2017. That role put Dennis at the forefront of a wide range of environmental policy issues in the Pacific Northwest and Alaska, including development of cleanup plans for the Seattle and Portland harbors.
