What Marten Law does

Marten Law LLP is a Seattle-headquartered environmental, natural resource, and energy law firm organized as a Washington State Limited Liability Partnership. The firm was founded in 2002 and employs approximately 30 lawyers across six offices in Seattle, New York, Washington DC, Portland, Boise, and Toronto. Its practice is focused exclusively on environmental and energy law, with representation across litigation, regulatory counseling, and transactional matters for Fortune 100 corporations, municipal and state governments, and innovative venture-backed startups.

The firm's service portfolio is organized around specialized practice areas including PFAS and Emerging Contaminants, Water Rights and Resources, Climate Change, Electric Power and Utilities, Refining and Petrochemicals, Solid and Hazardous Waste Management, and Consumer Products compliance. Core subject-matter expertise spans CERCLA, RCRA, the Clean Water Act, the Safe Drinking Water Act, FERC licensing, NEPA, the Endangered Species Act, and state climate superfund laws. Notable engagements include representation of the New York City Department of Environmental Protection on Gowanus Canal and Newtown Creek Superfund sites, the State of New York in CERCLA cost recovery actions, and counsel on matters involving more than 100 parties and over $1 billion in damages, including legacy work on Exxon Valdez and Deepwater Horizon litigation.

Marten Law generates revenue through professional service fees for litigation and regulatory advisory work, primarily on an hourly billing model with potential alternative fee arrangements for complex matters. The firm's go-to-market relies on attorney reputation, Chambers USA and Best Lawyers recognition, professional referrals, and recurring thought leadership through its newsletter, webinars, and industry association participation. Its competitive positioning is anchored in single-practice focus, senior talent depth led by founder Bradley Marten, and a national cross-border footprint that combines regional expertise in the Pacific Northwest and Mountain West with east coast and Canadian capabilities.

Expansion highlights6 records

Emerging players

• Earthjustice: Earthjustice is the largest nonprofit environmental law organization in the US, frequently litigating against the same regulated entities that Marten Law defends. It is a thematic peer because its Clean Water Act, CERCLA, and climate cases shape the precedent environment that Marten's corporate clients must navigate.
• Environmental Defense Fund: EDF is a major environmental advocacy organization with an in-house legal and policy team that intervenes in rulemakings and litigation. It sits on the opposite side of many matters in which Marten Law's corporate clients are involved, making it thematically comparable for climate, PFAS, and Clean Air Act practice.

Broad incumbents

• Davis Wright Tremaine LLP: Davis Wright Tremaine is a Pacific Northwest-headquartered firm with a deep environmental and energy practice, including climate change, water law, and natural resources. It overlaps with Marten in Seattle, Portland, and Washington DC and serves similar utility and manufacturing clients.
• Latham & Watkins LLP: Latham & Watkins is a global AmLaw 5 firm with a market-leading environmental, energy, and climate practice. It competes with Marten on the largest PFAS, climate disclosure, and ESG matters, representing the broad incumbent that specialty boutiques measure themselves against on high-end mandates.
• Sidley Austin LLP: Sidley Austin is an AmLaw 20 global firm with a long-standing environmental practice covering CERCLA, Clean Air Act, and climate matters. It serves many of the same Fortune 100 and energy clients as Marten, providing the broad-incumbent comparator for high-stakes environmental litigation and regulatory work.
• Perkins Coie LLP: Perkins Coie is a Pacific Northwest-rooted AmLaw firm with environmental, energy, and climate practices spanning CERCLA, water rights, and ESG. It competes with Marten for Seattle and Portland-based clients and serves overlapping Fortune 100 and clean tech customers.

Direct peers

• Van Ness Feldman LLP: Van Ness Feldman is a Pacific Northwest-rooted boutique (now part of the firm's national platform) historically focused on energy, environment, and natural resources law. It overlaps directly with Marten on hydroelectric licensing, FERC matters, and environmental permitting in the same regional market.
• Hunton Andrews Kurth LLP: Hunton Andrews Kurth operates a prominent environmental and energy practice serving electric power, water, and manufacturing clients. It is comparable to Marten Law in practice mix but is broader in scope and significantly larger, offering useful context for Marten's specialty positioning.
• Beveridge & Diamond PC: Beveridge & Diamond is a leading national environmental and energy law boutique with offices across the US. It is the most direct comparator to Marten Law, matching its single-practice focus on environmental law and overlap on CERCLA, RCRA, Clean Water Act, and PFAS matters for Fortune 500 clients.
• Stoel Rives LLP: Stoel Rives is a Pacific Northwest full-service firm with a substantial energy, environment, and natural resources practice. It competes with Marten for utility, mining, and water rights clients, particularly in Portland, Boise, and Seattle, while offering broader corporate services that complement but overlap with Marten's specialty focus.
