Injured on the Job? Do This First

Our Story

A Paper Route, a Picket Line,
and a Billion Dollars Recovered for Clients

One of us started as a bag boy at Albertson's, making journeyman in the union at 16. The other organized garment workers across the American West. We became lawyers because we'd already spent years fighting for working people — and decided to get better tools.

How a Union Grocery Clerk and a Labor Organizer Built a Law Firm

Bob Arns grew up in Portland, Oregon in a family with limited means — his father never completed high school, his mother's education ended there too. He started working a paper route and lawn jobs as a kid, became a bag boy at Albertson's at 14, and by 16 had made journeyman in the union as both a checker and produce worker. During his junior year of high school, he was managing night stock operations twice a week — working alongside older hands who taught him things no classroom could. He graduated with highest honors from UC Santa Barbara and finished in the top 5% of his class at USF School of Law on a full scholarship, where he was managing editor of the law review and moot court champion.

He could have gone anywhere. He chose to represent plaintiffs — the people on the wrong end of a corporate balance sheet — because he'd been one of them. He founded the firm more than 40 years ago in San Francisco on a premise that still drives everything we do: ordinary people deserve the same caliber of legal representation as the insurance companies and corporations opposing them. From the start, the practice focused on injured workers in the trades — both workers' compensation and third-party civil claims against the contractors, property owners, and equipment manufacturers responsible for unsafe jobsites.

Jonathan Davis came to the law from a different direction. Before he ever set foot in a courtroom, he served as an International Representative and National Field Director for the Amalgamated Clothing and Textile Workers' Union, representing workers in arbitrations across the West and organizing on picket lines. When he joined the firm, he brought something you can't teach in law school — an instinct for how working people actually experience the legal system, and a trial approach shaped by years of labor campaigns. He now leads the firm as Managing Partner, overseeing case strategy, mentoring younger attorneys, and maintaining the relationships with labor organizations that have been central to the practice since the beginning.

The firm's other practice areas didn't come from a business plan — they grew from the work itself. When you represent injured workers and their families long enough, you start to see the full scope of what they're up against. The same employer shorting a worker on overtime is doing it to dozens of others. The product that injured someone on a jobsite turns out to be defective across the country. A company markets a consumer product that's quietly harming the same communities you've been serving for decades. So the practice expanded — into class actions for wage theft, consumer fraud, product liability, sexual abuse — not because we wanted to diversify, but because our clients and their families needed us to. The core of the firm is still injured workers in the trades. But now we go after all the ways their families are being harmed, on and off the jobsite.

What Happens When You Hire Us

Most people have never worked with a plaintiff law firm before. Here's what the experience actually looks like at Arns Davis.

You Get a Lawyer, Not a Funnel

A lot of firms advertise on TV, sign you up, and hand your file to a paralegal you'll never meet. That's not how we operate. Your attorney gives you their personal cell phone number. When you have a question at 8 p.m. about what your doctor said, you call them directly.

Trial Preparation Starts on Day One

Bob Arns literally wrote the book on trial practice — The Evidence Wheel and The Trial Wheel are used by lawyers and judges nationwide. Our building at 515 Folsom has facilities to mock-try cases before 36 jurors in three separate deliberation rooms. That infrastructure isn't decorative. Every case is prepared as if it's going in front of a jury, because insurance companies settle differently when they know you mean it.

One Firm Handles Everything

A construction worker falls from scaffolding. There's a workers' comp claim for immediate medical care and lost wages. There may also be a civil case against the general contractor or equipment manufacturer. If the employer has been misclassifying workers, there could be a class action. Most firms handle one of those. We handle all three — and we manage the interplay between them so nothing falls through the cracks.

We Speak Your Language

Several of our attorneys and staff are fluent in English and Spanish, including partners and hearing representatives who handle cases day-to-day. This isn't a translation service bolted onto an English-language practice — it's built into how we work with clients from the first phone call through resolution.

We Take the Hard Cases

A $13 million consumer protection case against an energy drink company selling a product laced with an addictive opioid. A nationwide class action against Amazon over gig-worker misclassification. A sexual abuse case against U.S. Figure Skating. We don't shy away from complex litigation or powerful defendants. Our track record is built on cases other firms wouldn't touch.

You Pay Nothing Unless We Win

We work on contingency. There's no hourly billing, no retainer, no invoice at the end of the month. Our fee comes from the recovery we obtain for you — which means our incentives are perfectly aligned with yours. If we don't get you a result, you owe us nothing.

The Work That Doesn't Show Up on the Court Docket

Bob Arns taught trial practice as an adjunct professor at USF School of Law for 21 years, co-creating the Arns Brandi Trial Center — a certificate program that ensures graduates can actually try a case from discovery through closing argument. He has served as a Board Member for Bay Area Legal Aid and spent seven years working with Legal Aid of Napa Valley, hosting California Supreme Court Justices at educational presentations. His ABOTA "Masters of Trial" presentations — over ten of them — have trained the next generation of plaintiff trial lawyers across the country.

Jonathan Davis served as Chairman of the African-American Construction Workers Association, a nonprofit affordable housing organization, before he ever tried a case. He currently sits on the Board of Directors of the Local 261 Community Service and Training Foundation and previously served on the Board of Governors of the Consumer Attorneys of California. That civic work isn't a line on a résumé — it's the reason he became a lawyer in the first place.

We join amicus briefs on cases that affect workers' rights. We show up at union halls, not for client development, but because the labor movement's fight is our fight. When a firm treats legal work as purely transactional — take the fee, close the file, move on — the clients can feel it. We're here because we believe the tradespeople who build our cities and keep our infrastructure running deserve advocates who care about more than the billable hour.
