WhatleyKallas

What WhatleyKallas does

Whatley Kallas LLP is a Birmingham, Alabama-headquartered healthcare litigation boutique operating as a limited liability partnership with approximately 101-250 employees and ten offices across the United States (New York, Boston, Atlanta, Aspen, San Diego, San Francisco, Los Angeles, Orlando, Portsmouth, and Birmingham). The firm represents healthcare providers — including physicians, hospitals and hospital systems, ambulatory surgical centers, and durable medical equipment providers — in litigation, arbitration, and contract negotiations against health insurers, with deep institutional ties to the American Medical Association and six major state medical societies (New York, California, Florida, Texas, South Carolina, Tennessee). The firm's core practice addresses wrongful claim denials, underpayments, unfair contract terms, antitrust violations, and interference with the doctor-patient relationship, and it has negotiated settlements valued in the billions including the $2.8 billion Blue Cross Blue Shield Provider Antitrust Settlement (effective September 2025) — the largest antitrust settlement in U.S. healthcare industry history — plus injunctive relief valued at a minimum of $17.3 billion.

The firm generates revenue through two primary streams: contingency-fee representation in class actions and major antitrust litigation (where fees are a percentage of settlements or judgments recovered), and hourly or flat-fee representation for ongoing legal work including contract negotiation and consultation with healthcare providers. Beyond healthcare, the firm pursues antitrust and complex commercial litigation — including a $1.28 billion jury verdict against Tyson Fresh Meats for cattle ranchers — as well as consumer fraud and abuse class actions. Notable client outcomes include over $1.5 billion in settlements from In re Managed Care Litigation, a $130 million settlement plus $2 billion in practice changes in Love v. Blue Cross Blue Shield, and the certified class of approximately 900,000 physicians in the BCBS MDL.

Go-to-market is reputation-driven and referral-based, leveraging medical association endorsements, recognition in The National Law Journal and American Lawyer, Law360 Rising Stars distinctions, and Super Lawyers listings rather than traditional advertising. The firm was reorganized in 2013 from predecessor Whatley Drake & Kallas LLC, though its founding partners' healthcare antitrust practice extends back further. The firm is privately held with no parent company, external institutional investors, or subsidiaries.

Core offering

Whatley Kallas is a healthcare-focused plaintiff-side litigation boutique that represents physicians, medical associations, hospitals, ambulatory surgical centers, durable medical equipment providers, and consumer class members against major U.S. health insurers and large corporations. The firm handles nationwide antitrust class actions (notably the $2.8 billion Blue Cross Blue Shield settlement), reimbursement and contract disputes, RICO cases, and consumer fraud class actions. Services are delivered as contingency-fee representation for major litigation and hourly/flat-fee representation for contract negotiations and ongoing counsel.

Product overview

WhatleyKallas is a law firm offering legal services, not a technology product company. The firm provides legal representation and litigation services across three primary practice areas: Healthcare (representing healthcare providers in disputes with insurers, reimbursement issues, and antitrust matters), Antitrust and Complex Commercial Litigation (including price-fixing, market allocation, RICO cases), and Consumer Fraud & Abuse (class actions addressing unfair or deceptive practices). The firm has no software products, platforms, or named digital service offerings.
