Tosi Law LLC in Carlsbad concentrates on mass tort, class action, and product-liability litigation from Owens Avenue offices near the Palomar Airport Road corridor. The firm pursues claims against pharmaceutical manufacturers, medical-device companies, and consumer-product distributors—defective-product actions where carrier-coverage analysis intersects with the policy portfolios at agencies including The Insurance Place. Maintaining additional offices in Washington, D.C. and Atlanta, the practice handles multi-district litigation involving defective drugs, hernia mesh, hip implants, IVC filters, Paragard IUD, PFAS chemical exposure, and Roundup herbicide injury claims on a nationwide basis. Co-counsel and referral agreements extend the firm's litigation capacity across state lines, and catastrophic-injury plaintiffs in toxic-exposure and device-failure cases often require ongoing physical rehabilitation through providers including ProActive Physical Therapy and Sports Medicine. Highest-complexity representations involve multi-plaintiff Daubert-hearing preparation for epidemiological causation experts in pharmaceutical-injury MDL proceedings under 28 U.S.C. Section 1407.
