Glendale Obstetrics & Gynecology Data Breach Exposes Patient Information
In October 2025, Glendale Obstetrics & Gynecology, a medical practice based in Glendale, Arizona, suffered a data breach that may have compromised sensitive patient information. The incident was disclosed to the New Hampshire Attorney General on April 13, 2026, with notification letters sent to affected individuals beginning April 9, 2026.
On October 25, 2025, the practice detected a network disruption and launched an investigation, which later confirmed that an unauthorized individual had accessed certain files. A review of the affected data, completed on March 16, 2026, revealed that personally identifiable information including names, Social Security numbers, dates of birth, addresses, and driver’s license details may have been exposed. Additionally, protected health information, such as medical records and health insurance data, was potentially compromised.
In response, Glendale Obstetrics & Gynecology is offering affected individuals 12 months of free credit monitoring, credit reports, and fraud assistance through Cyberscout, a TransUnion company. Enrollment is available via a unique code provided in notification letters, with a 90-day window for activation. A dedicated support line (1-833-289-6054) is also available for assistance during business hours.
The total number of individuals impacted across the U.S. has not been disclosed.
