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.
