Glendale Obstetrics & Gynecology Data Breach Exposes Sensitive Patient Information
Shamis & Gentile P.A., a class action law firm specializing in data breach cases, is investigating a cybersecurity incident involving Glendale Obstetrics & Gynecology (GOG), a women’s healthcare provider based in Glendale, Arizona. The breach, discovered in October 2023, resulted in the unauthorized access and exfiltration of sensitive patient data.
GOG, led by Dr. Diana Heard and Nicola Maurer, WHNP, provides obstetric, gynecological, and reproductive health services at its location in Glendale, AZ. On October 25, 2023, the practice detected a network disruption and launched an investigation, later confirming that an unauthorized party had accessed files containing personally identifiable information (PII).
The exposed data includes names, Social Security numbers, addresses, dates of birth, driver’s license details, health insurance information, and medical records. While the total number of affected individuals remains undisclosed, GOG completed its review and began notifying impacted patients in April 2026.
The incident highlights ongoing risks to healthcare data security, with legal firms now evaluating potential compensation claims for those affected. The breach underscores the vulnerability of sensitive medical and personal information in digital healthcare environments.
