What Mullen & Filippi, LLP does

Mullen & Filippi, LLP is a California-based law firm founded in 1949 that provides legal representation and advice to employers, insurance carriers, and third-party administrators in the defense of workers' compensation matters. The firm operates from a Sacramento headquarters and 14 additional California offices spanning the Bay Area, Central Valley, Los Angeles metro, Orange County, Inland Empire, and San Diego. Practice areas are organized around five specializations: Workers' Compensation defense, OSHA Defense, Asbestos Defense, Subrogation, and Serious & Willful Misconduct / L.C. 132(a) Discrimination defense. The firm is majority woman-owned, certified as a Women's Business Enterprise through the Women's Business Enterprise National Council (WBENC), and recognized with the California State Bar DEI Leadership Gold Seal.

The firm's core offering is professional legal services delivered by 80+ attorneys, including Board Certified Workers' Compensation Specialists and senior partners with multi-decade practice tenure. The technology stack consists of standard IT infrastructure supporting secure client data management and customized case handling, supplemented by a public-facing online Compensation Calculator that allows visitors to estimate disability benefits. The firm publishes educational bulletins, case briefs, and tailored on-site workshops, and runs a "Refer a Case" intake system that funnels work from its referral and association network (VICA, AWCP, NCCIPMA, PELRA, CAJPA, FIRMA). There are no disclosed APIs, SDKs, integrations, or AI/ML capabilities.

The revenue model is professional services fees — primarily hourly or flat fee billing negotiated with clients — paid by employers, insurance carriers, and third-party administrators for workers' compensation defense matters; fees are not publicly disclosed and the firm does not report financials. Pricing follows a monthly billing cadence with quote-based engagement terms, supported by free initial consultations. The go-to-market motion is relationship-led and content-led, leveraging long-standing carrier/TPA panel positions, a statewide seminar program, and organic inbound via the firm website and referral network.
