By Ask ten people which firm is the biggest name in personal injury law, and you’ll probably hear the same billboard-friendly answer. But “biggest” is not one thing. A firm can lead the pack in attorney headcount, in the size of the checks it writes to injured clients, or in the number of nine-figure verdicts it has on the board & those are frequently three different lists.
This guide breaks down the firms that dominate personal injury law by size, reach, and results, and explains why the largest firm on paper is not always the right firm for a given case.
What “Largest” Really Means in Personal Injury Law
Before ranking anyone, it helps to be honest about what “size” is measuring, because plaintiff firms tend to be big in one of three distinct ways.
Scale and National Footprint
Some firms measure size the way a retail chain would: total attorneys, number of offices, states covered, and advertising reach. These firms are built to intake enormous volumes of cases and run them through a standardized process.
Litigation Capital and Infrastructure
Other firms stay leaner on headcount but pour resources into the machinery mass-tort and toxic-exposure litigation demands – in-house medical and scientific staff, proprietary case databases, and the capital to front years of expert costs before a single settlement check arrives.
Verdict and Settlement Records
A third group is genuinely small, sometimes under 20 lawyers – yet routinely produces the eight- and nine-figure verdicts that make headlines. On a dollars-recovered-per-attorney basis, these boutique trial shops can outperform firms ten times their size.
Any credible ranking of the largest personal injury law firms in the country needs to account for all three, which is why the list below is organized into tiers rather than a single strict order. Headcounts and recovery figures cited here are current-best estimates drawn from firm-reported data and public sources; firms merge, rebrand, and grow throughout the year, so treat exact numbers as directional. With one flagged exception, every firm below is a plaintiff-side practice, meaning it represents injured people, not the companies or insurers being sued.
Tier 1: The National Volume Leaders
These firms operate at a scale closer to a national brand than a traditional law practice, with hundreds of attorneys and case-intake operations running in nearly every state.
1. Morgan & Morgan
Founded in Orlando in 1988, Morgan & Morgan is, by any conventional measure, the largest personal injury law firm in the United States. The firm now employs more than 1,100 trial attorneys across roughly 140 offices in all 50 states plus Washington, D.C., and reports having recovered over $35 billion for more than 700,000 clients. No competitor comes close on raw headcount, and the firm handles nearly every category of injury claim, from car accidents to mass torts and class actions.
2. Thomas J. Henry Injury Attorneys
Based out of San Antonio with additional hubs in Austin, Houston, Corpus Christi, and Dallas, Thomas J. Henry has built a Texas-rooted operation of more than 250 attorneys and a support staff exceeding 450 people. The firm has become known for an intake and advertising operation aggressive enough to make it one of the few genuine national-scale challengers to Morgan & Morgan.
3. Wilshire Law Firm
Founded in 2007 by Bobby Saadian, Wilshire has grown into one of California’s largest plaintiff practices, with more than 100 attorneys and upward of 500 total staff. The firm runs a heavily tech-enabled intake and case-management operation covering auto accidents, catastrophic injury, employment claims, and mass torts.
4. The Carlson Law Firm
Operating since 1976, Carlson has expanded to roughly 50 attorneys across 20-plus offices, with a deep Texas base now extending into Florida. Its neighborhood-office model gives it a geographic reach that outpaces what its headcount alone would suggest.
Tier 2: The Mass-Tort and Toxic-Exposure Powerhouses
These firms don’t necessarily chase headcount. Instead, they build the specialized infrastructure – scientific staff, medical consultants, and case databases – that pharmaceutical, asbestos, and environmental litigation requires.
5. Weitz & Luxenberg
Founded in 1986 and headquartered in New York, with additional offices in Los Angeles, Detroit, and Cherry Hill, New Jersey, Weitz & Luxenberg fields more than 100 attorneys alongside a science and experts division that rivals the legal staff of smaller full-service firms. The firm has recovered billions across asbestos, defective drug, and environmental contamination cases.
6. Simmons Hanly Conroy
Headquartered in Alton, Illinois, with offices including New York, Chicago, San Francisco, and St. Louis, Simmons Hanly Conroy is one of the country’s leading mesothelioma and asbestos litigation firms. Its roughly 100 attorneys generate recoveries better measured in litigation firepower and revenue per lawyer than in office count.
7. Beasley Allen
Founded in Alabama in 1979 by former Governor Jere Locke Beasley, Beasley Allen fields more than 80 attorneys and roughly 285 total staff across Montgomery, Mobile, and Atlanta while litigating nationwide. The firm reports having handled matters totaling more than $27 billion, including an $11.9 billion verdict against an oil company and a $4.85 billion pharmaceutical settlement, and it has played a leading role in recent J&J talc and Camp Lejeune water-contamination litigation.
8. Goldberg, Persky & White P.C.
A four-decade specialist in mesothelioma and asbestos-related disease across Pennsylvania, Michigan, and West Virginia, this firm’s real advantage is a proprietary database of asbestos worksite and job-history records that few competitors can replicate: making it one of the more quietly influential firms in this category despite a modest headcount.
9. Pintas & Mullins Law Firm
Founded in Illinois in 1985, Pintas & Mullins built an “intake and co-counsel” model that acquires cases nationwide through a digital-first operation, then partners with specialized litigators for medical malpractice, nursing home abuse, and product liability matters.
Tier 3: The Elite Trial and Verdict Firms
These firms keep attorney counts deliberately small while producing some of the largest verdicts in American legal history.
10. Kline & Specter, P.C.
Often described as Philadelphia’s most powerful plaintiff firm, Kline & Specter fields more than 40 attorneys, including five who also hold medical degrees – reportedly more physician-attorneys than any other firm in the country. In 2019, founding partner Tom Kline helped secure an $8 billion punitive-damages verdict against Johnson & Johnson over the antipsychotic drug Risperdal, among the largest single-plaintiff jury verdicts in Pennsylvania history (later reduced on appeal).
11. Corboy & Demetrio
A Chicago institution with roughly 20 attorneys, Corboy & Demetrio has secured more than $5 billion in verdicts and settlements over its history, including hundreds of results exceeding $1 million, and remains a go-to firm for national aviation-disaster litigation.
12. Searcy Denney
Operating from West Palm Beach, Tallahassee, and Tampa, this 37-attorney Florida firm reports verdicts and recoveries approaching $6 billion, including a $1.58 billion verdict against Morgan Stanley in 2005, and is known for funding litigation costs many smaller firms have to refer elsewhere.
13. Gair, Gair, Conason, Rubinowitz, Bloom, Hershenhorn, Steigman & Mackauf
This 17-attorney New York firm consistently posts among the highest average verdicts in the city for truck accidents, construction claims, and general personal injury litigation.
14. Abraham, Watkins, Nichols, Agosto, Aziz & Stogner
Houston’s oldest personal injury firm, operating for more than 70 years with around 24 attorneys, Abraham Watkins remains one of Texas’s most established plaintiff practices and a frequent “best law firm” honoree.
Tier 4: The Regional and Niche Leaders
Dominance here comes from market saturation in a state or city, or from a specialty deep enough to function as a competitive moat.
15. The Barnes Firm
The surviving half of the former Cellino & Barnes partnership, The Barnes Firm has rebuilt into a high-volume regional presence with an estimated 50 to 70 attorneys across Los Angeles, San Diego, San Francisco, New York City, Rochester, and Buffalo, concentrating on motor-vehicle and slip-and-fall claims.
16. Cellino Law
The other half of that split, now led by Ross Cellino, has grown to an estimated 35 to 50 attorneys, with more than $2 billion in reported recoveries and offices in Manhattan, Buffalo, Rochester, Melville, Brooklyn, and Bridgeport, Connecticut.
17. Sullivan Papain Block McGrath Coffinas & Cannavo P.C.
One of New York’s oldest contingency-only practices, with around 19 attorneys, this firm recovered more than $1 billion in September 11th Victim Compensation Fund settlements for first responders – a scale of mass-claim administration few firms of its size can match.
18. Hach & Rose
Led by Michael Rose and former labor lawyer Gregory Hach, this 17-attorney New York firm has built deep ties to the city’s labor unions that function as a referral network rivaling firms with much larger advertising budgets, concentrating on construction and labor-related accidents.
19. The Rothenberg Law Firm LLP
Founded in New York in 1969, Rothenberg has spent more than five decades handling car accidents, medical malpractice, and construction injury claims for clients across the region.
20. Goldberg Segalla (Flagged Listing)
With more than 400 attorneys across 20 offices in 10 states, Goldberg Segalla is genuinely one of the larger litigation firms in the country by headcount – but it is primarily a defense and multi-practice firm that frequently represents insurers and corporate defendants, not injured plaintiffs. It appears here for scale and because its product-liability and worksite litigation intersects the personal injury world, but anyone searching for a lawyer to represent them after an injury should understand this is not typically a plaintiff-side firm.

Does the Largest Personal Injury Law Firm Automatically Win the Most Cases?
Not necessarily. Size buys a firm resources: expert witnesses, accident reconstruction specialists, and the ability to front years of litigation costs – but it doesn’t guarantee that any single attorney at that firm will try your case personally, or that the firm’s trial record in your specific type of claim is strong. A firm with a thousand attorneys handling routine car-accident settlements is not automatically better positioned for a complex medical malpractice or mesothelioma claim than a 20-lawyer firm that has tried dozens of exactly that case type to verdict.
What Makes a Large Personal Injury Firm Actually Worth Hiring
Three factors separate the firms that earn their size from firms that simply spend heavily on marketing.
- Resources. Litigation is expensive well before it pays off. Large firms can front the cost of medical experts, economists, and investigators, recovering those costs only if the case succeeds — which matters enormously in catastrophic-injury and mass-tort claims.
- Trial credibility. Insurance companies track which firms actually take cases to verdict and which always settle. A firm willing to go to trial typically negotiates from a stronger position.
- Specialization. The strongest large firms concentrate specific attorneys on specific injury types: mesothelioma, trucking, product liability, medical malpractice — so a case lands with someone who has run that exact playbook before.
The trade-off is straightforward: a national firm may treat a case as one of thousands in its pipeline, while a smaller specialist can offer more direct attention. It’s reasonable, and advisable, to ask at an initial consultation who will actually handle the file day to day, how many comparable cases the firm has taken to verdict, and what its trial record actually looks like.
How Do Personal Injury Contingency Fees Work?
Nearly every firm on this list, large or small, works on a contingency-fee basis: no fee is owed unless the firm wins or settles the case. The attorney’s cut is typically negotiated as a percentage of the recovery, commonly in the 33% to 40% range depending on the firm and on whether the case settles early or proceeds to trial. Case expenses: expert witnesses, filing fees, accident reconstruction – are usually advanced by the firm and deducted from any final recovery. Anyone hiring a firm should get the fee percentage, expense handling, and any pre-suit versus post-suit fee differences confirmed in writing before signing.
Key Takeaways
- Morgan & Morgan remains the largest personal injury law firm in the US by attorney count and geographic reach, but “largest” splits into at least three separate categories: national scale, mass-tort litigation infrastructure, and elite verdict records.
- Mass-tort powerhouses like Weitz & Luxenberg, Simmons Hanly Conroy, and Beasley Allen compete on litigation capital and specialized case infrastructure rather than headcount alone.
- Boutique trial firms such as Kline & Specter, Corboy & Demetrio, and Searcy Denney often out-earn far larger firms on a per-attorney basis by winning high-value verdicts.
- Regional leaders, including The Barnes Firm, Cellino Law, and Hach & Rose, dominate specific states or niches through saturation advertising or referral networks rather than nationwide reach.
- Goldberg Segalla is a large litigation firm by headcount but is primarily a defense practice, not a plaintiff-side personal injury firm, and should not be confused with the other firms on this list.
- Firm size should never be the only factor in choosing representation. The right firm is the one with proven experience in the specific type of claim involved, a credible trial record, and a fee structure confirmed in writing before signing.
Frequently Asked Questions
-
Which is the largest personal injury law firm in the US?
Morgan & Morgan is the largest personal injury law firm in the country by attorney headcount and office footprint, with more than 1,100 attorneys operating in all 50 states.
-
How should “largest” be measured for a personal injury firm?
There’s no single correct metric. Attorney count and office footprint measure reach; reported recoveries and case values measure financial scale; verdict history measures litigation strength. A complete picture of the largest personal injury law firms looks at all three rather than ranking on headcount alone.
-
Does hiring one of the largest personal injury law firms guarantee a better settlement?
No. A larger firm generally brings more resources and negotiating leverage, but outcomes still depend on the specific facts of a case, the assigned attorney’s experience with that claim type, and whether the firm has a genuine record of taking similar cases to trial.
-
Is Goldberg Segalla a personal injury law firm for injured plaintiffs?
Not typically. Goldberg Segalla is one of the largest litigation firms in the country by headcount, but it primarily represents insurers and corporate defendants rather than injured individuals, which distinguishes it from the plaintiff-side firms elsewhere on this list.
-
What should someone ask before hiring one of the largest personal injury law firms?
Useful questions include who will personally handle the case, how many similar claims the firm has taken to verdict rather than settled, what the fee percentage and expense structure look like in writing, and how often the client should expect direct communication with an attorney rather than a case manager.
-
Are smaller personal injury firms ever a better choice than the largest ones?
Often, yes, particularly for cases requiring deep specialization — such as medical malpractice or a specific type of toxic exposure — where a smaller firm’s trial record in that exact area can matter more than a larger firm’s overall size.
