Welcome to Mullen & Filippi

Founded in 1949, the firm of Mullen & Filippi has become known throughout California as the leader in Workers' Compensation defense law. This reputation is sustained by the firm's resolve to ensure its attorneys, and clients, are among the best informed in the field. Continuously and thoroughly apprised of changes in both applicable law and special procedures governing litigation, our firm also provides numerous means - thorough seminars, in-house workshops, timely bulletins and a host of online resources - by which any interested party can become well-informed.

Managers face enormous pressure to get cases resolved. Adjusters bear the additional burden of recent reforms focused on getting the injured worker back to work. Each client and each case presents unique requirements, and Mullen & Filippi is committed to meeting those requirements. Our relationship with our clients is marked by the day-to-day responsiveness that is absolutely critical to efficient and successful defense of claims. We understand that in your business, time is of the essence.

Rather than perpetuate the impression that lawyers are keepers of a cryptic language incomprehensible to the layperson, our firm believes that open dissemination of useful information benefits us all. Our responsiveness to the developments in legal practice - and to the individual employees and insurance carriers we represent before the California Workers' Compensation Appeals Board - is what has fueled our firm's growth for over five decades.


    Mullen & Filippi is proud of the legal services it provides to public and private employers, insurance carriers, and third party administrators in a variety of practice areas, including: Workers' Compensation, Employment Law, Subrogation, Third-Party Liability Defense Claims and the coordination of multi-forum litigation.
