Our Story

Built Here.
Serving Northern California Since 1996.

Originally established in 1996, the firm has since evolved into O’Brien & Zehnder, providing injured clients with the experience and resources needed to take on insurance companies and large corporations while maintaining the personal attention of a smaller firm.

Over the last 30 years, our firm has grown, but the way we practice law has remained personal. Our attorneys and staff work closely together, our clients know the people handling their cases, and every case receives the individual attention it deserves. Today, O’Brien & Zehnder represents clients throughout Elk Grove, Sacramento, and Northern California in serious personal injury, wrongful death, product liability, construction, and other complex cases.

What Makes Us Different

Big-Firm Experience.
Small-Firm Attention.

There are plenty of law firms that can handle a personal injury claim.
We believe the difference is in how you are represented.

You Know Your
Legal Team

Our clients are not passed from department to department or treated like a case number. You will know the attorneys and staff working on your case, and our team will know you.

We Stay
Personally Involved

Every case is different. We take the time to understand our clients, their injuries, their families, and how an accident has affected their lives. That personal involvement allows us to tell our clients’ stories and advocate for what they have truly lost.
