John M. O'Brien & Associates, P.C. was formed with one thought in mind: justice for injured victims. Our record over the past eighteen years proves how successful we have been in achieving that goal. It remains our singular mission even today.

We have the experience, expertise and resources to take on any defendant, large or small, to ensure justice for our clients.

As a firm, we pride ourselves on giving each client the individual attention he or she deserves. You are not a case number to us. You are someone who is deserving of our utmost attention and skill. We take the time to learn about you and what makes your case unique, so that we are always prepared when it comes time to negotiate a resolution or present a closing argument to a jury.

Aside from experienced trial counsel, our staff is also highly qualified. Our paralegal, Kathy Long, and legal assistant, Brenda Marchant, have over 40 years of experience between them in the Sacramento legal community. They are always willing and eager to assist the firm's clients with their questions or concerns.
