A dual-office plaintiff’s firm serving two of Arizona’s more isolated legal markets — the desert border city of Yuma and southern Tucson — with a bilingual practice built around vehicle-collision and medical-negligence litigation.

Origin: A Long Run in a Small Market — With Some Disagreement on How Long
Karnas Law Firm’s own Yuma page states: “Since we opened our doors in 1983 our personal injury attorneys and law firms have recovered more than $50 million in settlements for our clients.” Other firm-affiliated listings describe “25 years of experience” instead, and lead attorney Matthew David Karnas’s own biography describes “a career spanning over 27 years” personally. We present all three figures rather than picking the one that sounds best.
What is consistent: Karnas Law Firm is licensed in both Arizona and California, built around Yuma — a desert border city roughly three hours from both Phoenix and San Diego — later adding a second office in Tucson.
The Attorney: A Focus on Vehicle and Motorcycle Litigation
Matthew David Karnas is described by the firm as specializing in vehicle and motorcycle crash litigation. The firm’s marketing also lists recognition names including “Best Law Firm in America 2023” and “National Top 100 Trial Lawyers” — several of which are paid or nomination-based legal-marketing recognitions common across the industry rather than the peer-reviewed, no-cost selection processes behind Best Lawyers or Super Lawyers.
Practice
The firm handles car, truck, and motorcycle collisions; pedestrian accidents; medical negligence and malpractice claims; dangerous and defective products; and mass tort claims, on a contingency-fee basis with free consultations and Spanish-language service.
Track Record
Karnas Law Firm publishes a cumulative figure rather than an itemized case list: more than $50 million recovered since the firm’s reported 1983 opening. No itemized, case-by-case results table was located.
Past-Results Disclaimer: Every case is different, and results depend on each matter’s specific facts. Prior results do not guarantee a similar outcome in any future matter.
Recognition, With a Caveat
The firm’s published recognitions — including “10 Best Attorney Client Satisfaction” and “Lawyers of Distinction” — come from legal-marketing recognition programs rather than peer-nominated, research-driven processes. Readers should weigh these accordingly. The firm’s Facebook page separately notes a “Voted Yuma’s Best” community recognition.
The Arizona Legal Backdrop
What follows is general legal information, not legal advice.
Arizona gives most personal-injury plaintiffs two years to file suit (A.R.S. § 12-542) and follows pure comparative negligence (A.R.S. § 12-2505). Because the firm’s practice includes medical-negligence claims, Arizona generally requires a preliminary expert affidavit early in a medical malpractice case (A.R.S. § 12-2603).
The Awesome Attorneys Assessment
Karnas Law Firm’s case rests on longevity and geography: a firm that has practiced injury law in Yuma for at least a quarter-century, in a market most Phoenix- or Tucson-based firms don’t prioritize. The honest trade-offs: an unresolved discrepancy about how long the firm has existed, a single cumulative results figure rather than itemized case results, and several “awards” that require more scrutiny than a Best Lawyers or Super Lawyers selection.
