What Happened?
According to Glendora Surgery Center’s public notice, the organization identified suspicious activity on a limited portion of its computer network and then began an investigation with the help of third-party cybersecurity specialists. The notice states that, based on that investigation, Glendora later determined that certain patient medical information was accessed and taken without authorization during the late-November to early-December 2025 timeframe.
The notice also says Glendora reviewed the impacted data to determine what information was present and who was affected, then conducted a record-validation process to prepare notifications. Glendora further states that it had no indication of identity theft or fraud related to the event at the time of the notice.
What Information Was Exposed?
The public notice identifies the information in the affected systems as name and medical treatment information. In practical terms, that means the reported incident may have involved patient health records or information connected to care received at the surgery center.
The notice reviewed here does not publicly list broader categories beyond those items. It also states that, to Glendora’s knowledge, the reported event involved Glendora information rather than Woodglen information.
What Should You Do Next?
- Review medical and financial activity carefully. Check explanations of benefits, provider statements, insurance records, and account statements for charges, services, or claims you do not recognize.
- Get your free credit reports. You can request reports from all three major credit bureaus at AnnualCreditReport.com and look for unfamiliar accounts or inquiries.
- Consider extra credit protections if you are concerned. A fraud alert or credit freeze can help reduce the risk of new accounts being opened in your name.
- Watch for phishing and impersonation attempts. Be cautious with calls, emails, or texts that reference medical treatment, bills, insurance issues, or requests for personal information.
- Keep records and ask questions. Save any notice you received, document unusual activity, and contact the assistance line listed by Glendora at (888) 202-1910 if you want more detail about what may have been involved.
- Consider getting legal guidance. If you are worried about misuse of your information or want to understand your options, you can contact Strauss Borrelli PLLC or fill out the form on this page for a case review.
