O'brien & Zehnder Law Firm

What O'brien & Zehnder Law Firm does

O'Brien & Zehnder Law Firm, P.C. (operating as "OZ Law") is a personal injury and wrongful death law firm based in Elk Grove, California, founded in 1994. The firm represents individuals in Sacramento County and surrounding areas (including Folsom, Rancho Cordova, Citrus Heights, Isleton, and Galt) who have suffered injuries due to the negligence of others. Practice areas span car, motorcycle, truck, bicycle, pedestrian, construction, dog bite, spinal cord, and brain injury cases, plus wrongful death claims. Three named attorneys lead the practice: John M. O'Brien, Grant R. Zehnder (26+ years of PI experience), and Joel M. Smith.

The firm operates on a contingency fee model with no upfront cost to clients; fees of roughly one-third to 40% of recovery are charged only upon successful resolution. Free initial consultations are offered and intake is available 24/7 via phone, web contact form, and in-person visits to the single Elk Grove headquarters. Cumulative case outcomes exceed $250 million recovered across thousands of concluded cases, including marquee results of $17.65M (wrongful death, 2020), $16.6M (crosswalk brain injury), and $8.5M (fatal pool equipment defect). Marketing relies on a content-heavy website with dedicated practice-area pages, blog, FAQ content, testimonials, case results showcases, earned media (Fox 40 News interviews), and listings on legal directories (Avvo, Martindale-Hubbell, Super Lawyers, NAOPIA, National Trial Lawyers, Three Best Rated, Expertise.com, Trust Analytica, Sacramento Magazine, SEOlium).

There is no proprietary technology platform, no AI/ML capability disclosed, no app, no API, and no external institutional investment. The firm is a privately-held professional corporation with traditional partnership structure; revenue is not publicly disclosed. Competitive positioning rests on three decades of localized experience, top-tier peer ratings (AV Preeminent 5/5, Avvo 10/Superb), trial-tested litigation posture, and breadth of practice-area specialization within personal injury law.

Revenue model

1. Contingency Fee Legal Services: The firm operates on a contingency fee arrangement for personal injury cases. Clients pay no attorneys' fees unless the firm successfully recovers compensation. If the case is won, the lawyer receives a fixed percentage (typically one-third to 40%) of the settlement or civil judgment. If the case is lost, the client owes no attorneys' fees. This model provides access to justice for clients who cannot afford legal representation upfront.
