Wagstaff & Cartmell

What Wagstaff & Cartmell does

Wagstaff & Cartmell LLP is a privately held, Kansas City-based litigation boutique founded by Thomas P. Cartmell, operating as a Missouri limited liability partnership with offices at 4740 Grand Avenue in Kansas City and 1717 K Street NW in Washington, DC. The firm employs 80+ attorneys, paralegals, and support staff and concentrates exclusively on complex, high-stakes litigation, with primary practice areas spanning mass tort and personal injury, class actions and commercial litigation, product liability (especially pharmaceutical and medical device MDLs), governmental representation, appellate practice, criminal defense, and emerging areas such as social media addiction litigation.

The firm's business model rests on a hybrid fee structure typical of plaintiff-side litigation boutiques: contingency-fee representation for individuals, families, small businesses, and public entities in plaintiff matters; hourly billings for defense work for Kansas City enterprises; and bespoke fee arrangements for Attorneys General and government retainers. Distribution is mediated principally by federal and state court appointments to MDL Plaintiffs' Steering Committees, which have placed Wagstaff & Cartmell in leadership roles in over 30 multidistrict proceedings (including seven pelvic mesh MDLs covering 100,000+ plaintiffs that yielded $7.25 billion in settlements, Benicar, JUUL, social media addiction, GLP-1 receptor agonist, Roblox, and Oracle/Cerner), with peer recognition and government retainers complementing inbound demand. The firm has secured 50+ favorable jury verdicts and recovered over $2 billion for clients across its history, with Managing Partner Sarah Ruane and Founding Partner Tom Cartmell as primary leaders and a partnership group including multiple ABOTA, International Society of Barristers, and Super Lawyers honorees.
