John Parker Sweeney


Every mass tort matter may involve "bet the company" risks, and Mr. Sweeney's experience with major product liability and toxic tort cases allows him to develop a litigation response tailored to the many variables of each matter. He regularly serves as national counsel, devising and executing comprehensive defense strategies in mass tort cases across the country and, because of the critical advantage provided by his familiarity with state and federal courts in the Mid-Atlantic region, his regional mass tort practice is unsurpassed. He is recognized as a Maryland "Super Lawyer" in mass tort defense.

An acknowledged "expert on experts," Mr. Sweeney relies on his relationships with nationally renowned technical, scientific, and medical experts, as well as his thorough understanding of the rules and procedures governing expert testimony to protect his clients from scientifically unfounded claims and unqualified plaintiffs' experts. His success at securing precedent-setting decisions limiting the admission of junk science in early "sick building" claims typifies his effectiveness.

Mr. Sweeney provides effective mass tort risk-management and cost recovery advice based on over 30 years of complex litigation experience. He advises clients on how to avoid or mitigate the risks of product liability and environmental claims. He regularly investigates and secures insurance coverage or contractual indemnification.
