About the Investigation:


Have you been a patient at any of the following medical groups?

  • Regal Medical Group
  • Lakeside Medical Organization
  • ADOC Medical Group
  • Greater Covina Medical

If so, your data may have been stolen!

On February 10, 2023, it was announced that a California medical group had suffered a cyberattack to its network that affected 3.3 million patients. The Heritage Provider Network system includes different medical groups, so the data breach exposed the information of patients of Regal Medical Group, Lakeside Medical Organization, ADOC Medical Group and Greater Covina Medical.  The information accessed by the hackers included patients’ names, addresses, phone numbers, Social Security numbers, dates of birth, private medical information, and health plan numbers.

Data breaches are serious matters that can cause long term damage. Hackers break into networks so that they can steal your personal information to sell it on the dark web, commit identity theft, financial theft or other frauds.

How do you know if you were affected? If you received a letter from Heritage Provider Network, Regal Medical Group, Lakeside Medical Organization, ADOC Medical Group, or Greater Covina Medical saying that your personal information was impacted in their data breach, contact us to find out if you may be eligible for compensation!
