He serves as co-chair of the firm’s Product Liability and Mass Torts Practice Group, which was named for the third time as the Product Liability Litigation Department of the Year by The American Lawyer. Mike has been recognized by Chambers as “a true product liability lawyer’s lawyer,” emphasizing “his strengths in strategy and briefing on mass torts.” The American Lawyer has named him a “Litigator of the Week” on three separate occasions, including most recently for successfully defending the first alleged heavy metals in baby food case to reach a jury.
