Nestled along the vibrant Pacific coastline, California—with its nearly 40 million residents—basks in glitz, innovation, and cinematic allure. Yet millions also face the harsh realities of chronic illness, accidents, or unexpected health crises. Insurance is meant to provide peace of mind during these moments, but far too often, claims are denied when people need support the most.
California’s robust insurance regulations empower policyholders to push back against these denials and demand fair treatment. At the forefront of this fight is Kantor & Kantor, LLP, California, a firm devoted solely to representing individuals in disputes involving disability, health, life, and long-term care benefits. Founded in 2004 and headquartered in Northridge, the firm has expanded across the West Coast, building a reputation for being one of the most trusted voices in insurance law.
What sets Kantor & Kantor apart is its rare combination of compassion and litigation strength. With deep expertise in ERISA and insurance law, their team takes a strategic yet client-centered approach, ensuring that policyholders have a fierce advocate when facing insurance giants.
Founding Partners: Glenn R. Kantor & Lisa S. Kantor
Glenn R. Kantor, co-founder and senior ERISA litigator, has over three decades of experience holding insurance companies accountable. He played a pivotal role in the passage of California Insurance Code Section 10110.6, which eliminated insurers’ ability to deny claims through discretionary clauses. Glenn has represented thousands of clients suffering from conditions such as multiple sclerosis, Parkinson’s, cancer, and fibromyalgia, and is known for his sharp legal strategy and unwavering advocacy.
Lisa S. Kantor, the firm’s other founding partner, is nationally recognized for her work in mental health and eating disorder litigation. She has been at the forefront of cases that challenged how insurers treat mental health claims, winning decisions that expanded access to necessary care under parity laws. Her groundbreaking legal work has earned her consistent recognition as one of the top insurance attorneys in the country.
Together, Glenn and Lisa have built a firm rooted in both legal excellence and genuine empathy for their clients—people often at the lowest points in their lives.
