About Hanning & Sacchetto, LLP — Personal Injury Whittier, California
Hanning & Sacchetto, LLP handles personal injury Whittier cases for accident victims across Southern California, with offices in Whittier, Arcadia, Pomona, Ontario, Glendora, Irvine, and Santa Ana. Partners Nathan A. Hanning and Michael V. Sacchetto both previously worked as defense attorneys for large insurance companies before switching sides to represent injured plaintiffs — an inside-out perspective that shapes how they build and present cases against the same insurers they once defended. The firm operates on a contingency fee basis: clients pay nothing unless they recover compensation. Whittier residents can also explore the Whittier attorney directory for additional options.
Whittier sits in Los Angeles County, and most personal injury lawsuits for Whittier clients are filed in the Whittier Courthouse at 7339 South Painter Avenue or the main Los Angeles County Superior Court complex in downtown LA. The firm’s multi-office footprint across the San Gabriel Valley, Inland Empire, and Orange County means clients injured anywhere in Southern California can access representation without traveling far. Hanning & Sacchetto’s former defense experience means they know which arguments insurers use to minimize claims — and how to counter them.

Frequently Asked Questions
What is the contingency fee arrangement in California personal injury cases?
A contingency fee means the attorney charges no upfront costs and takes a percentage of the recovery — typically 33% if the case settles before trial, higher if it goes to verdict — only when the client wins. If you lose, you owe nothing in attorney fees. California Rules of Professional Conduct require contingency fee agreements to be in writing. The contingency structure aligns the attorney’s financial interest with the client’s — the attorney only profits when the client does.
How does California’s strict liability dog bite law work in Whittier?
California Civil Code § 3342 makes dog owners strictly liable for bites that occur in public places or when the victim is lawfully on private property. Unlike many states that require proof that the owner knew the dog was dangerous, California imposes liability on the first bite — no prior knowledge of aggression is required. The bite must be a bite specifically, not a scratch or knock-down, though those injuries may be covered under general negligence principles.
What information should I collect after an accident in Whittier, California?
Immediately after any accident, document the scene with photographs, get the names and contact information of all involved parties and witnesses, and file a police report. For vehicle accidents, get the other driver’s insurance information and license plate. Seek medical attention promptly — delayed treatment creates gaps in the medical record that insurers use to challenge injury claims. Store all medical bills, treatment records, and communications with insurance companies, and contact an attorney before giving any recorded statement to the other party’s insurer.
