What Koszdin, Fields & Sherry does

Koszdin, Fields & Sherry (also referenced in materials as Koszdin, Fields, Sherry & Katz and abbreviated "KFSK") is a private California law firm founded in 1955 and headquartered in Van Nuys, California. The firm specializes in workers' compensation and Social Security Disability representation for individual injured workers across Southern California, operating from five offices in Van Nuys, Los Angeles, Lancaster, Palmdale, and Santa Clarita. Its primary client base is employees who have sustained work-related injuries or illnesses and need legal assistance to obtain medical benefits, temporary or permanent disability benefits, or Social Security Disability benefits, including victims of denied claims, workplace accidents, repetitive motion injuries, work-related mental health claims, and fatal workplace injuries.

The firm operates on a contingency fee basis — charging no attorney fees unless a case is won — and offers free initial consultations to reduce client-acquisition friction. Its product surface comprises a workers' compensation core practice plus modular service lines covering medical benefits, disability benefits, permanent disability, denied claim appeals, work-stress/mental health claims, pre-existing injury aggravations, and Social Security Disability. The firm employs approximately 10 people and is staffed by State Bar of California Certified Specialists in Workers' Compensation Law, including managing partner Susan E. Fields and partners Mark J. Sherry and Brett T. Sherry, alongside attorney Michael Fields.

Koszdin, Fields & Sherry pursues a sales-led, geographically constrained go-to-market model. Marketing is concentrated on local SEO through location-specific landing pages, an extensive blog covering workers' compensation topics, organic social media presence on Twitter, Facebook, and LinkedIn, and referrals reinforced by published client testimonials. The firm is privately held with no institutional investors, parent company, acquisitions, or funding rounds, and has no disclosed technology platform, software products, integrations, or AI/ML capabilities — its deliverables are attorney-led legal services.

Expansion highlights4 records

Broad incumbents

• Wilshire Law Firm: California-based plaintiff firm with a workers' compensation and personal injury practice. Comparable as a California-anchored plaintiff firm competing for the same injured-worker client pool, but with a broader practice mix and larger marketing budget.
• Morgan & Morgan: National plaintiff-side law firm with a workers' compensation practice. Comparable as a competing brand in the same plaintiff workers' comp category, but operates at significantly larger scale and broader geographic footprint.

Direct peers

• Gordon, Edelstein, Krepack, Grant, Felton & Goldstein, LLP: Long-established California workers' compensation defense and applicant-side firm with multiple California offices. Directly comparable as a multi-attorney California workers' compensation practice serving injured workers and operating on similar contingency-fee economics.
• Law Offices of Lawrence D. Rohlfing: California-based Social Security Disability practice. Directly comparable for the firm's SSD line of service, which represents a meaningful portion of the firm's caseload.
• Allred, Maroko & Goldberg: Los Angeles-based law firm specializing in workers' compensation and employment law matters. Directly comparable in geography (Southern California), practice mix (workers' comp with adjacent employment claims), and contingency-driven plaintiff representation.
• Gurewitz & Gurewitz: California workers' compensation law firm representing injured workers statewide. Directly comparable in specialty focus (applicant-side workers' comp), client type (injured workers), and contingency fee structure.

Others

• Binder & Binder (formerly The Binder Law Firm): Historically the largest U.S. Social Security Disability and workers' compensation applicant-side firm before its 2014 bankruptcy. Relevant historical peer whose rise and collapse illustrates the scale economics and concentration risk inherent in contingency-fee SSD/WC mass practice.
