Our Mission

As the largest workers’ compensation law firm in Contra Costa County, we have the resources to fully investigate the circumstances of your case, and we are unafraid to take on big insurance companies. Yet we never lose sight of our true purpose, which is to help every client get the compensation and medical care they need.

Our office is in Antioch, California, and we represent clients throughout Contra Costa County and Alameda County. You can schedule your free consultation by calling 866-432-2133, or through email.


Both partners at Ivancich & Costis, LLP, are certified mediators. Even if you are already represented regarding your workers’ compensation claim, we may be able to help you, your attorney and the insurance company come to an agreement to settle your claim. Mediation fee quotes are available upon request.

For Women Injured At Work

If you are a woman and are going through the workers’ compensation system regarding an injury of a sensitive nature, Ivancich & Costis, LLP, offers a women-only experience through the Women Injured at Work branch of the practice if you would prefer that your claim only be handled by women attorneys and staff. Please contact our office to learn more about this option of representation.
