John Parker Sweeney has more than 30 years of experience defending major class action and mass torts involving product liability and warranty, consumer protection, environmental, and toxic tort cases, allowing him to tailor an appropriate litigation response for any company to resolve "bet-the-company" risks. He regularly serves as national litigation counsel, creating and supervising comprehensive defense strategies in class action and mass tort cases across the country, most recently sweeping the board clean of a series of warranty class actions against an international construction product manufacturer.

John’s effectiveness and national prominence as a defense lawyer for business in class action and mass torts was recognized by his peers when he was elected as  2014-2015 president of DRI—The Voice of the Defense Bar, a 22,000-member association of defense lawyers.

John relies on his relationships with internationally renowned scientific, technical, and medical experts, as well as his thorough understanding of the rules and procedures governing expert testimony in both Daubert and Frye jurisdictions to protect his clients from scientifically unfounded claims and unqualified plaintiffs' experts. His success at securing precedent-setting decisions excluding junk science from the courtroom in "sick building" claims typifies his effectiveness.

John is devoted to his pro bono relationship with the Helping Up Mission, Inc. of Baltimore, a faith-based residential recovery program for homeless addicts. For over 10 years, John has led a team of lawyers providing free legal services and counseling for the mission’s residents.
