Trial-Ready Representation

A California Trial Bench, Not a Settlement Mill

The attorneys of Keosian Law LLP have spent decades trying cases in California state and federal court. Our firm was built around a single premise: that meaningful recoveries for injured people, grieving families, and policyholders come from lawyers who know how to win in front of a jury — not from intake mills that rely on volume and quick settlements. Every attorney on our team is selected for litigation ability first, with the courtroom temperament, technical command, and preparation standards that complex California cases demand.

How our team is organized

Our practice is organized around four litigation groups, each led by senior attorneys with focused subject-matter experience. Files move through the firm with clear ownership: a lead trial attorney who answers for case strategy, an associate or senior associate handling day-to-day discovery and motion practice, a dedicated case manager who stays in direct contact with the client, and an in-house investigation team that gathers and preserves evidence from the first 48 hours of the matter onward.

We deliberately keep individual caseloads lower than the regional norm so that each attorney has the bandwidth to prepare cases for trial — not just for mediation. That structure means the carrier on the other side cannot count on a quiet file. Depositions are taken. Experts are retained. Motions are briefed thoroughly. And when settlement negotiations begin, they begin from a posture of credibility that has already cost the defense significant time and money to defend against.

Litigation credentials and bar admissions

Our attorneys are admitted to practice before all California state courts and the United States District Courts for the Central, Southern, Eastern, and Northern Districts of California, with additional admissions to the United States Court of Appeals for the Ninth Circuit on appellate matters arising out of our trial work. We hold active membership in the Consumer Attorneys of California, the Consumer Attorneys Association of Los Angeles, the Los Angeles County Bar Association, and other plaintiff trial bar organizations through which our team contributes to continuing legal education in personal injury, insurance bad faith, and complex litigation.

Several attorneys at the firm have lectured on California insurance-coverage doctrine, the FAIR Plan claims process, and wildfire litigation strategy. That body of work is one reason carriers and defense firms know our names well before the first deposition is noticed.

Practice areas the firm accepts

Our attorneys handle matters across four core California practice categories. Each link below leads to a detailed practice page with case-type breakdowns, the law that controls those claims, and what evidence we typically need to evaluate a new file.

Mass tort and complex investigations

Beyond individual representation, members of our trial team lead the firm's California mass tort program. Active investigations include the Eaton Fire, Palisades Fire, Chiquita Canyon Landfill, Quemetco / Ecobat lead contamination, and the California FAIR Plan underpayment program. These matters require coordination across multiple attorneys, expert witnesses, and document-review teams. Our staffing model supports that scale without compromising the attention given to standalone individual cases.

Mass tort representation at Keosian Law LLP is structured around three commitments: (1) every client is screened and signed by a licensed California attorney, not a call-center operator; (2) clients receive a named case manager and direct attorney access throughout the investigation; and (3) we do not refer cases out to volume firms once signed — the trial team that opens the file is the trial team that tries it. A complete index of active and resolved investigations is available on the mass torts hub.

Choosing the right attorney for your matter

Below this section, you will find each attorney's biography, focus areas, and contact information. If you are not sure which attorney is the best fit for your matter, you can request a free, confidential consultation and our intake team will route the call to the appropriate practice group lead. We will tell you honestly whether your case fits our practice, what we believe the strongest legal theory is, and what immediate steps you should take to preserve evidence — whether or not you ultimately retain Keosian Law LLP.

No attorney fees or costs unless we recover for you. Business and corporate matters are quoted on an engagement-by-engagement basis after an initial scoping call. All consultations are free.
