The Personal Injury Law Firm List Of The Largest in the Business
By LawFuel Staff — Updated July 10, 2026
Largest personal injury law firm in America: Morgan & Morgan is the largest personal injury firm in the United States by a wide margin, with more than 1,100 attorneys, roughly 140 offices across all 50 states, and a reported $35 billion-plus recovered for over 700,000 clients. No other plaintiff firm is close on headcount.
Read our in-depth answer: What is the largest personal injury law firm in America?
How We Ranked Them (And What “Largest” Actually Means)
“Largest” is a slippery word in personal injury law, and any honest list has to admit it up front. A firm can be enormous in three quite different ways:
- By headcount and reach — hundreds of lawyers, dozens of offices, nationwide advertising. Morgan & Morgan and Thomas J. Henry are giants in this sense.
- By litigation firepower — smaller teams that deploy vast capital, in-house experts and proprietary databases to win mass-tort and toxic-exposure cases. Weitz & Luxenberg and Simmons Hanly Conroy live here.
- By verdict record — boutique trial shops of 15 to 40 lawyers that quietly out-earn the mega-firms on a per-attorney basis because they win the eight- and nine-figure cases. Kline & Specter and Corboy & Demetrio are the archetype.
We’ve drawn on American Lawyer and National Law Journal (NLJ 500) data, firm-reported figures, and public court records, and we’ve grouped the twenty into four tiers so a 250-lawyer firm doesn’t end up ranked below a 17-lawyer one.
Where a number comes from the firm itself rather than an independent source, we say so. Firms grow, split and rebrand constantly, so treat the headcounts as current-best estimates, not gospel.
One caveat worth stating plainly: this is a list of plaintiff-side firms, the ones that represent injured people, with a single flagged exception at the end.
Tier 1 — The National Volume Giants
The firms that operate less like law practices and more like national legal utilities: huge staff, saturation advertising, and a case-intake machine running in every state.
1. Morgan & Morgan
Founded in Orlando in 1988 by John and Ultima Morgan, Morgan & Morgan is the undisputed heavyweight — and by its own “Size Matters” logic, it never lets you forget it.
The firm now fields more than 1,100 trial-ready attorneys and a support army of several thousand, spread across roughly 140 offices in all 50 states plus Washington, D.C. It reports having recovered over $35 billion for more than 700,000 clients, and it is the only firm here that consistently cracks the Law360 400 on size alone. It handles the full consumer spectrum — auto and truck accidents, product liability, mass torts, class actions and employment.
- Attorney count: 1,100+
- Reach: All 50 states; ~140 offices
- Distinction: The “Amazon” of injury law — scale as a strategy.
2. Thomas J. Henry Injury Attorneys
The Texas-born challenger that has spent the last few years scaling toward true national reach. With over 250 attorneys and a support workforce north of 450, Thomas J. Henry runs one of the most aggressive advertising and intake operations in the country from hubs in San Antonio, Austin, Houston, Corpus Christi and Dallas. Its calling card is the high staff-to-attorney ratio — cases worked at industrial speed against Fortune 500 defendants.
- Attorney count: 250+
- Distinction: Volume and infrastructure; a genuine rival to Morgan & Morgan on ad spend.
3. Wilshire Law Firm
Founded by Bobby Saadian (pictured) in 2007, Wilshire has grown into California’s tech-enabled PI powerhouse, with 100-plus attorneys and more than 500 team members. It treats legal service as a data-driven enterprise, handling car accidents, catastrophic injury, employment and mass torts, and has eclipsed many older California firms in a little over fifteen years.
- Attorney count: 100+
- Distinction: West Coast infrastructure leader.
4. The Carlson Law Firm
Representing injured clients since 1976, Carlson bridges the gap between a neighbourhood firm and a national one, with roughly 50 attorneys across 20-plus offices — a heavy Texas footprint now extending into Florida. Its “local office everywhere” model gives it a volume reach that belies its headcount.
- Attorney count: ~50
- Distinction: Rapid multi-state, neighbourhood-office expansion.
Tier 2 — The Mass-Tort Powerhouses
Capital-intensive firms built for asbestos, pharmaceutical, environmental and product-liability litigation — the cases that require war chests, science departments and years of patience.
5. Weitz & Luxenberg
Founded in 1986 by Jerry Weitz and Arthur Luxenberg, this is one of the great engines of American mass-tort litigation, with 100-plus attorneys and a “Science and Experts” department larger than some entire law firms. It has recovered billions across asbestos, defective drugs and medical devices, and environmental contamination, operating from New York (HQ), Los Angeles, Detroit and Cherry Hill, NJ.
- Attorney count: 100+
- Distinction: Asbestos and environmental titan.
6. Simmons Hanly Conroy
One of the nation’s leading asbestos and mesothelioma firms, Simmons Hanly Conroy pairs mass-tort scale with pharmaceutical and product-liability work. The firm fields around 100 attorneys and reports recoveries well into the billions, with hubs in New York, Chicago, San Francisco, St. Louis and El Segundo, and headquarters in Alton, Illinois. Its size is best measured in litigation power and revenue-per-lawyer rather than raw headcount.
- Attorney count: ~100
- Distinction: Mass-tort litigation firepower.
7. Beasley Allen
Founded in 1979 by former Alabama governor Jere Locke Beasley, Beasley Allen is one of the country’s most consequential plaintiff firms — 80-plus attorneys and 285-plus staff across Montgomery and Mobile, Alabama, and Atlanta, Georgia, litigating nationwide. The firm reports having handled matters totalling more than $27 billion and holds multiple US records, including an $11.9 billion verdict against an oil company and a $4.85 billion pharmaceutical settlement. Recent headline results include a $235 million Altria/Juul settlement and a leading role in the J&J talc and Camp Lejeune litigation.
- Attorney count: 80+
- Distinction: National record-holder in complex plaintiff litigation.
8. Goldberg, Persky & White P.C.
A “boutique giant” in toxic torts, GPW has spent four decades on mesothelioma and asbestos-related disease, with a mid-sized team of specialist litigators backed by medical experts and records researchers. Its true asset is a proprietary database of asbestos worksites and job-site histories that smaller firms simply cannot replicate, anchored in industrial hubs across Pennsylvania, Michigan and West Virginia.
- Distinction: Asbestos/mesothelioma specialist with a proprietary evidence base.
9. Pintas & Mullins Law Firm
Founded in 1985 and based in Illinois, Pintas & Mullins pioneered the “intake and co-counsel” model — a national digital footprint that acquires cases across all 50 states and litigates them with specialised partners. Notably, it runs an in-house team of software engineers; its “size” is as much digital as it is legal, spanning medical malpractice, nursing home abuse and product liability.
- Distinction: National digital intake and litigation-management machine.
Tier 3 — The Elite Trial & Verdict Firms
Smaller by headcount, seismic by result. These “size by success” firms keep lawyer numbers deliberately low and out-earn the mega-firms per attorney on the strength of record verdicts.
10. Kline & Specter, P.C.
Frequently called the most powerful plaintiffs’ firm in Philadelphia, Kline & Specter fields 40-plus attorneys — including five who are also medical doctors, the most physician-attorneys of any firm in America. It handles medical malpractice, product liability and civil rights, from offices in Pennsylvania, New Jersey, Delaware and New York. In 2019, Tom Kline (with co-counsel Arnold & Itkin) won the landmark $8 billion punitive-damages verdict against Johnson & Johnson over the drug Risperdal — the largest single-plaintiff jury verdict in Pennsylvania history, later reduced on appeal.
- Attorney count: 40+
- Distinction: Medical-legal firepower and record-setting verdicts.
11. Corboy & Demetrio
A Chicago institution. With around 20 attorneys, Corboy & Demetrio has nonetheless secured more than $5 billion in verdicts and settlements and claims over 600 results exceeding $1 million. It is the go-to firm for national aviation disasters and high-profile Chicago litigation — a legacy trial powerhouse that proves headcount and heft are not the same thing.
- Attorney count: ~20
- Distinction: Legacy trial power; aviation and catastrophic injury.
12. Searcy Denney
A four-decade Florida institution with 37 attorneys across West Palm Beach, Tallahassee and Tampa. The firm reports verdicts and recoveries approaching $6 billion, including a $1.58 billion verdict against Morgan Stanley in 2005, and is known for the “war chest” to fund the multi-million-dollar litigation that smaller local firms must refer out.
- Attorney count: 37
- Distinction: Florida’s premier litigation firm.
13. Gair, Gair, Conason, Rubinowitz, Bloom, Hershenhorn, Steigman & Mackauf
A very long name attached to a very long list of verdicts. This 17-attorney New York firm bills itself as the city’s premier personal injury shop and reliably posts among the highest average verdicts in New York — truck and auto accidents, construction claims and the full plaintiff spectrum.
- Attorney count: 17
- Distinction: Highest average verdicts in NYC.
14. Abraham, Watkins, Nichols, Agosto, Aziz & Stogner
Houston’s oldest personal injury firm, in operation for more than seventy years, with around 24 attorneys and billions in reported recoveries. A perennial “best law firm” honouree, it remains one of Texas’s most established plaintiff practices.
- Attorney count: ~24
- Distinction: Texas’s oldest PI firm; deep trial pedigree.
Tier 4 — The Regional & Niche Leaders
Dominant in a state, a city, or a specialty — firms whose “size” is really market saturation or a proprietary network.
15. The Barnes Firm
The surviving half of the former “Cellino & Barnes,” The Barnes Firm has rebuilt itself into a high-volume regional force with an estimated 50–70 attorneys across major metros — Los Angeles, San Diego, San Francisco, New York City, Rochester and Buffalo. Heavy advertising makes it appear larger than its headcount suggests, with a focus on motor-vehicle and slip-and-fall cases.
- Attorney count: 50–70
- Distinction: Post-split high-volume advertiser.
16. Cellino Law
The other half of the old partnership. Post-split, Ross Cellino (pictured) built Cellino Law into a New York saturation play with an estimated 35–50 attorneys, reporting over $2 billion in recoveries. Offices in Manhattan, Buffalo, Rochester, Melville and Brooklyn, plus Bridgeport, CT, give it statewide coverage that rivals national firms within New York.
- Attorney count: 35–50
- Distinction: New York statewide saturation.
17. Sullivan Papain Block McGrath Coffinas & Cannavo P.C.
One of the oldest and largest PI practices in New York, with around 19 attorneys working purely on contingency. The firm recovered over $1 billion in 9/11 Victim Compensation Fund settlements for first responders, giving it a logistical scale in mass-claim administration that few can match. Offices in New York and New Jersey.
- Attorney count: ~19
- Distinction: Public-servant and first-responder representation.
18. Hach & Rose
A 17-attorney New York firm led by Michael Rose (pictured) and former labour lawyer Gregory Hach. Not the biggest in the city, but a primary force in the NYC construction and labour-union accident market, with deep ties to New York labour organisations that function as a proprietary referral network — no TV ads required.
- Attorney count: 17
- Distinction: NYC construction and labour-union litigation.
19. The Rothenberg Law Firm LLP
Founded in 1969 and based in New York, Rothenberg has spent over half a century on car accidents, medical malpractice and construction claims, building a long record of substantial verdicts and settlements for injured clients across the region.
- Distinction: Long-established New York injury practice.
20. Goldberg Segalla
Included with a clear caveat. With 400-plus attorneys across 20 offices in 10 states, Goldberg Segalla is one of the 200 largest firms in the US — but it is primarily a defense and multi-practice firm that often represents insurance companies, not a plaintiff-side consumer firm like the others here. We list it for scale and because its product-liability and worksite litigation intersects the injury world, but injured individuals seeking representation should note the distinction: this is not a firm that typically acts for plaintiffs.
- Attorney count: 400+
- Distinction: Multi-practice litigation giant — defense-oriented (flagged).

The Verdict: Who’s Really “On Top”?
It depends on the yardstick.
- Largest by presence: Morgan & Morgan, comfortably. Nobody else has 1,100 lawyers and an office in every state.
- Largest by litigation assets: Kline & Specter, whose five physician-attorneys give it an in-house medical department that rivals the insurers it fights.
- Fastest-growing: Thomas J. Henry and Wilshire, scaling into 2026 at a pace the older firms can’t match.
- Largest by record-setting verdicts: Beasley Allen, holder of multiple US verdict and settlement records across product liability and mass torts.
The bigger point for any injured reader is the one the advertising budgets would rather you didn’t dwell on: the biggest firm is not automatically the best firm for your case. The right firm is the one with the specific expertise, trial record and resources your claim actually needs — and sometimes that’s a specialist boutique, not a national brand.

What Actually Makes a Large PI Firm Worth Hiring
Three things separate the genuine powerhouses from firms that merely spend heavily on billboards:
Resources. Serious injury litigation is expensive. Large firms front the cost of accident reconstructionists, medical experts, economists and investigators — and only recover those costs if they win. In catastrophic-injury and mass-tort cases, that war chest is often the difference between a fair result and a lowball settlement.
Trial credibility. Insurers track which firms actually try cases and which always settle. A firm with a live verdict record has leverage in negotiation that a “we always settle” shop simply doesn’t. Morgan & Morgan makes this explicit; the elite boutiques prove it case by case.
Specialisation. Big firms typically field attorneys concentrated in specific injury types — mesothelioma, medical malpractice, trucking, product liability — so your case is handled by someone who has run that exact play before.
The trade-off is the obvious one: a national firm may treat your case as one of thousands, while a smaller specialist offers more personal attention. Ask, at the first meeting, who will actually handle your file, how many similar cases they’ve taken to verdict, and what their trial record looks like.
How Contingency Fees Work
Nearly every firm on this list works on contingency: no fee unless they win, with the lawyer taking an agreed percentage of the settlement or verdict which are typically 33% to 40%, depending on the firm and whether the case settles or goes to trial. Case expenses (experts, filing fees, reconstruction) are usually advanced by the firm and deducted from the recovery. Before signing anything, get the fee structure, the expense treatment and the percentage split (pre- vs post-suit) in writing.
The Bottom Line
Choosing a personal injury firm is not a popularity contest decided by advertising volume. Match the firm to the case: look for a demonstrable track record in your type of claim, a real trial record, resources proportionate to what you’re up against, and a team you’re comfortable working with. The largest firms bring formidable resources and credibility — but “biggest” and “best for you” are not always the same name.
