Founded in 2004, Kantor & Kantor, LLP represents individuals and families in disputes with insurance companies and employee benefit plans. The firm does not represent insurers, employers, or plan administrators. That single limitation shapes everything about how the practice works - how cases are selected, how claims files are read, and how thoroughly the firm has come to understand the internal machinery by which benefits get denied. The firm serves clients from offices in Los Angeles, San Diego, San Francisco, and San Jose, California; Portland, Oregon; and Seattle, Washington, and also serves Orange County, California.
The firm's benefits work spans long-term and short-term disability, life and accidental death, long-term care, pension and retirement benefits, and the broader range of claims arising under ERISA. It handles matters at every stage, from the administrative appeal that preserves a claimant's record through trial in federal court and appellate review, and litigates both individual and class claims nationwide. Because ERISA-governed group coverage and individually purchased policies carry different procedures and different remedies, the firm maintains depth in both. Kantor & Kantor also represents homeowners in first-party property disputes, including wildfire claims, where California law provides bad faith and extracontractual remedies unavailable under ERISA.
Kantor & Kantor is further known for claims that other firms decline, including those involving conditions insurers routinely discount, including ME/CFS, Long Covid, fibromyalgia, autoimmune and neurological disease, and mental health conditions. That work has grown into sustained partnerships with patient advocacy and nonprofit organizations, which the firm treats as part of its practice rather than adjacent to it.
