What Blizzard does

Blizzard Greenberg PLLC is a Houston-based plaintiff-side litigation boutique that represents individuals harmed by defective pharmaceuticals, defective medical devices, personal injury incidents, sexual assault, human trafficking, and medical malpractice. The firm's practice portfolio spans large mass-tort dockets (Vioxx, Fen-Phen, Talcum Powder, Valsartan, CPAP, hernia mesh, IVC filters, transvaginal mesh, NeuroBlate) alongside premises-liability sexual assault matters against hotels, rideshare platforms, massage businesses, churches, schools, and institutional defendants such as Aramark. Founded circa 2001 by trial lawyers who previously represented corporations and insurers, the firm rebranded from Blizzard Law to Blizzard Greenberg PLLC in 2023 to reflect the partnership between founder Ed Blizzard (40+ years of experience, multiple MDL leadership roles) and Anna Greenberg. The firm operates from offices in Houston (headquarters at 2 Riverway Dr), Dallas, and Austin, serving clients nationwide.

The firm generates revenue exclusively through contingency fee arrangements, charging no upfront cost to clients and earning a percentage of settlements and verdicts. Acquisition channels combine attorney referrals, earned media (USA Today, New York Times, ABC, FOX, Texas Lawyer), repeat peer recognition (Super Lawyers, Best Lawyers, Lawdragon 500), and a multi-platform social and content presence. Notable outcomes include a 2021 record $44 million verdict against Hilton Hotels, ranked #1 on Texas Lawyer's Top Verdicts list that year. Headcount is in the 11–50 band and the firm is privately held as a Texas PLLC with no disclosed institutional ownership or external funding. The technology stack is minimal: the firm does not maintain a mobile app, API, or proprietary software product, and competitive advantage is derived entirely from human capital, case-specific expertise, and brand reputation rather than from technology or data assets.
