MWL is known for its cost-effective and practical solutions to insurance issues, yet maintains a strong resolve to take matters through trial if reasonable settlements cannot be obtained in defense matters or if reasonable recoveries cannot be negotiated in subrogation cases. Each of the firm’s attorneys has extensive jury trial experience and a strong record of obtaining defense verdicts and significant subrogation recoveries. Compare that with the experience of firms you are currently using.

A full range of insurance services are offered by the experienced attorneys at MWL, including exceptional and knowledgeable representation in the areas of subrogation, civil litigation defense, workers’ compensation defenseinsurance coverage, and defense of product liability claims with a focus on Asian manufacturers.
