Founding Partner

Attorney Lisa S. Kantor

Lisa Kantor is founding partner of Kantor & Kantor LLP. Lisa has focused her law practice on representing individuals whose health benefits have been denied for treatment of physical or mental illnesses. Since 2007, Lisa has been a nationwide advocate for patients suffering eating disorders and litigating denials of medically necessary treatment for eating disorders. Through Lisa’s dedication to her clients, Kantor & Kantor has become the only law firm in the country with a distinct health law practice staffed with attorneys experienced in the specific needs of clients who have been denied benefits for eating disorder treatment.

Attorney Lisa Kantor can help with:

Unmatched Experience & Skill

Lisa’s work includes federal lawsuits and administrative appeals to health plans that refuse coverage or discontinue benefits for treatment thereby forcing patients to be prematurely discharged. She handles multiple class actions regarding the systematic denials of mental health claims by insurance companies.

Lisa is an experienced appellate attorney and regularly argues appeals to the circuit court of appeals. In 2007, Lisa achieved the first published decision in California in which the court applied the state's mental health parity law to beneficiaries who sought treatment outside California. In 2012, Lisa obtained the first federal appellate court ruling that health plans in California must pay for all medically necessary treatment for severe mental illnesses, including residential treatment. In 2014, Lisa obtained a parallel state court appellate court ruling, extending coverage for all medically necessary treatment for severe mental illnesses to all residents of California.

Lisa’s advocacy extends to the legislature where she challenges inappropriate guidelines used to deny treatment and advocates for laws ensuring that health plans provide benefits for the medically necessary treatment of all individuals suffering from severe mental illnesses.

Ground Breaking Cases:

  • Rea v. Blue Shield: class action against Blue Shield of California finding the insurer must pay for medically necessary treatment, even though their plans specifically excluded it. Blue Shield was the only California insurance company that specifically excluded residential treatment in its plans, and the panel's decision on this case is recognition of the importance of such treatment for mental health care.
  • Harlick v. Blue Shield:landmark appellate court decision that ruled health plans must pay for all medically necessary treatment of severe mental illnesses under the same financial terms and conditions as they provide for physical illnesses. In particular, this ruling will help thousands of people suffering from eating disorders receive residential treatment crucial for recovery.
  • Burton v. Blue Shield of California: first decision interpreting Harlick and deciding that California's Mental Health Parity Act mandates that insurers provide benefits for residential treatment for major depressive disorder and panic disorder.
  • Shepard v. United HealthCare: Ms. Kantor successfully petitioned the California Department of Managed Health Care on behalf of a client with anorexia being discharged from a residential care facility, forcing her insurer to agree to pay for her treatment.
  • Jacobs v. Kaiser Foundation Health Plan: Ms. Kantor recovered benefits for a client suffering from bulimia when her medical plan declined to refer her to an out-of-plan treatment facility and refused to pay for the cost of treatment. The California Court of Appeal ruled that the decision to place the plaintiff in residential treatment, rather than follow the health insurers flawed treatment decisions, may have saved her life.
  • Thompkins v. BC Life & Health Insurance Co.: the first published appellate decision in California for an eating disorder case where her client was denied benefits for in-patient treatment of bulimia. The Court of Appeal interpreted California's mental health parity law to include beneficiaries from California policies who did not live in California and sought medical care outside of California.

Client Testimonials

  • Truly outstanding in every way!

    “Both Glenn Kantor and his associate attorney Brent Brehm are truly experts in the field of disability law. They handled a complex individual disability policy issue for me. Their knowledge of the law, coupled with their experience, resources, and tactical skills, helped me obtain results that exceeded my expectations. Truly outstanding in every way!”


  • I won the appeal.

    “Hi Glenn- This is a very belated thank you for your generous assistance and advice last summer, when I was appealing UBH's decision for my son. I won the appeal, at least for care at the partial hospitalization level (they wouldn't budge on residential, but the facility was accepting the partial care reimbursement for residential treatment). But the appeal was a great moral victory, and I think it's a great thing to have in the record, just in case he needs to go for treatment again. Thanks again for your generous help, I was very grateful for it. Wishing you a most happy Thanksgiving.”

    Terry S.

  • Your compassion for me and my situation is very much appreciated.

    “My thanks to you for pursuing my case with vigor. I don't know much about how these legal things are handled, but I could tell by your communications with me, making sure I was always informed, that you were on top of it all. Also, you were ALWAYS available to me to answer questions, and your compassion for me and my situation is very much appreciated. I have had limited exposure to the legal system and attorneys, but I have never been able to just call and talk to them, as I could with you. I always had to speak with someone in the office that couldn't really answer my questions.”


  • We will never forget the good you have done and may you continue to earn gold stars.

    “More than your skilled expertise, uncompromising professionalism and breadth of experience, we have been immensely impressed with the sincerity, generosity and integrity with which you conducted our affairs, acted on our behalf and guided us through the sometimes confusing process. Throughout, we developed a great respect for all of you and it is our wish that both collectively and individually, you experience continued professional success and personal gratification in all that you pursue. We will never forget the good you have done and may you continue to earn gold stars.”

    Lalida C.

  • You've helped to remove a great burden from our lives. It's nice to know there are decent people still in the world.
