About Gonzales Law Offices Accident Attorney Injury Lawyers · Ontario
Gonzales Law Offices is a Southern California personal injury law firm founded in 2013 by attorney Mark "The Shark" Gonzales, Esq. (California State Bar #249340), with offices across the Inland Empire including its Ontario location at 500 East E Street, Suite #407. The firm exclusively represents injured victims in car, motorcycle, truck, rideshare, pedestrian, slip-and-fall, brain injury, spinal cord, and wrongful death cases on a contingency-fee basis (no fee unless they win).

Gonzales Law Offices is a dedicated personal injury firm built around a single California-licensed attorney, Mark Gonzales, Esq., who has been admitted to the State Bar since June 5, 2007, after earning his Juris Doctor from the University of La Verne College of Law and his undergraduate degree from California Polytechnic State University. The firm was founded in 2013 and now operates four offices across the Inland Empire: Fontana (main headquarters, 7337 East Ave, Suite E), Ontario (500 East E Street, Suite #407), San Bernardino (2627 S Waterman Ave, Suite D), and Rancho Cucamonga (12365 Foothill Blvd, Suite 105). The Ontario office, situated in Executive Suites and easily accessible from I-10 and Omnitrans Route 87, serves injured residents of Ontario International Airport-adjacent neighborhoods and surrounding San Bernardino County communities. Before opening his own firm, Mark Gonzales worked in the insurance defense industry, an experience he cites as giving him insider insight into how insurers evaluate and contest claims — knowledge he now uses on behalf of plaintiffs. The firm handles the full range of personal injury matters that occur in the Inland Empire, including car and motorcycle accidents, semi-truck collisions along the busy I-10/I-15 freight corridor, Uber and Lyft rideshare crashes, pedestrian and hit-and-run incidents, dog bites, brain and spinal cord injuries, slip-and-fall/premises liability, severe burns, transportation accidents, uninsured-motorist claims, and wrongful death. Gonzales Law Offices works on a pure contingency-fee basis (clients pay nothing unless the firm recovers), offers free consultations around the clock, and provides complimentary rides via Uber or Lyft to clients who need transportation to the office. Notable reported results include a $4.2 million semi-truck collision settlement on I-10 in Fontana, a $2.8 million wrongful death recovery in San Bernardino, and a $1.5 million rideshare accident settlement in Ontario. The firm is bilingual (English and Spanish) and markets a 4.9-star Google rating across hundreds of verified reviews, an Avvo 10.0 "Superb" rating, BBB A+ accreditation, Super Lawyers recognition, and Lead Counsel verification.

California Personal Injury Law — What Ontario Drivers Should Know
The firm's Ontario car accident page explains the core California legal framework that applies to local injury claims. The statute of limitations for personal injury, product liability, and wrongful death claims is two years under California Code of Civil Procedure §335.1; claims against government entities must be filed within six months (Tort Claims Act). California is a pure comparative-fault state (Civil Code §1714), so an injured person can still recover damages even if they are partially at fault, reduced proportionally. Minimum liability insurance in California is $15,000 per person / $30,000 per accident / $5,000 property damage (Vehicle Code §16020); commercial vehicles must carry the FMCSA minimums of $750,000 to $5,000,000. The Ontario office's local knowledge section highlights the I-10/I-15 freight corridor, intersections such as San Antonio St and G St, and Ontario International Airport-related commercial traffic as frequent accident settings.
- Statute of Limitations: 2 years (CCP §335.1); 6 months for government claims
- Pure Comparative Fault (Civil Code §1714) — recover even if partially at fault
- Minimum liability insurance: $15K/$30K/$5K (Vehicle Code §16020)
- Commercial vehicle minimums: $750K–$5M (FMCSA)
- High-risk Ontario corridors: I-10, I-15, San Antonio St & G St intersection
