Unbound Expertise

Technically speaking, we’re based in the Pacific Northwest. But as a remote and decentralized firm, our team works from anywhere. This flexibility lets us provide legal expertise and responsiveness wherever you need it, without the constraints of traditional top-down systems.
Our decentralized model also comes with other perks like:
Big-firm Experience
Because we don’t ask clients to subsidize fancy offices or palatial conference rooms, we can charge reasonable rates for our extensive expertise.
Streamlined Operations
Without big-firm bureaucracy, we cut through red tape, allowing for flexibility and efficiency, particularly regarding fee arrangements, and responsiveness that is second to none.
Energized Attorneys
Our attorneys thrive in a remote environment, bringing fresh energy to your most challenging cases, from the places they love.
Practice Areas
We cover a broad spectrum of environmental law, from litigation and permitting to climate change, sustainability, and beyond.
Permit Litigation and Enforcement Defense
We advise clients at every stage in the life cycle of a permit dispute or enforcement case, from responding to information requests or notices of violation from government agencies to full-scale trials in federal court. We are also well-versed in out-of-court and pretrial dispute resolution, and have settled numerous enforcement cases with federal and state regulators involving water, air, remediation, and workplace safety issues.
Learn MoreRegulatory Compliance
Navigating the ebb and flow of environmental regulations requires specialized knowledge and expertise. Our team is comprised of leaders in the field, drawing from a deep well of experience to ensure you receive accurate and up-to-date advice tailored to your specific needs. We are forward-thinking, dedicated professionals well-versed in the latest environmental laws and
compliance requirements.
Sustainability and ESG
Headwaters Law Group partners with businesses that recognize the value of sustainability in protecting the environment, developing long-term growth strategies, engaging with customers, and mitigating risks. Our team helps clients track evolving greenhouse gas emission regulatory developments, climate disclosure requirements, and carbon offset protocols. We work with clients to assess risks and opportunities associated with environmental, social, and governance (ESG) policies, procedures, and inquiries.
Learn MoreContaminated Sites
Our team has advised multinational industry leaders, Ports, and small firms at some of the most complicated cleanup sites in the country, including the Lower Duwamish, Hudson, Kalamazoo, and Willamette rivers. We often serve as long-term, strategic counsel to entities that face significant risk at contaminated sites. We are partners for the long haul, from site investigation and remediation counseling to litigation or allocation.
