CMBG3 Law

What CMBG3 Law does

CMBG3 Law is a privately-held national litigation law firm founded in 2016 and headquartered in Boston, Massachusetts, operating as a professional corporation (CMBG3 Law, P.C.). The firm specializes in complex, high-stakes litigation at the intersection of law, science, and regulatory policy, with deep practices in product liability (asbestos, talc, benzene, silicosis), PFAS litigation, environmental and toxic tort defense, employment law, and commercial disputes. It serves Fortune 100/500 corporations, global insurers, regulated manufacturers, and — selectively — small businesses and individuals requiring sophisticated defense or regulatory counsel. The firm delivers services directly through six U.S. offices (Boston, Hartford, Pasadena, San Francisco, Providence, Swansea) and bar admissions in 14+ states, enabling coast-to-coast representation without local-counsel intermediation for multi-jurisdictional portfolios.

The firm's offerings are organized into two tiers: Practice Areas (Abuse/Harassment, Commercial Disputes, Employment Law, Environmental Law, General Litigation, Product Liability) and Professional Services (National Strategic Counsel, Trial Counsel, National Negotiation, Regulatory Compliance, Appellate Practice, Government Relations, Post Verdict Crisis Counsel), with further specialization in PFAS, Asbestos, Talc, Silicosis, Benzene, and Proposition 65 matters. Its revenue model is professional services-based, using flat fees, phased fee structures, and traditional hourly billing; pricing is not publicly disclosed. The go-to-market motion is enterprise field sales — direct engagement with Fortune 100/500 in-house counsel, insurers, and risk managers — supported by an active thought-leadership apparatus including a 1,000+ article legal intelligence publication, podcasts, webinars, conference speaking (Perrin, DRI, NAWL, EECMA, PCPC, Reuters), and earned media in the Wall Street Journal, Washington Post, Bloomberg, and Law360. The firm is majority women-owned, AV-rated by Martindale-Hubbell, and recognized twice by the National Law Review as the only national thought leader on PFAS, with 9 attorneys named Super Lawyers or Rising Stars in 2025.
