Mission Community Hospital Data Breach Investigation

Turke & Strauss LLP, a leading data breach law firm, is investigating Mission Community Hospital regarding its recent data breach. The Mission Community Hospital data breach involved sensitive personal information belonging to an undetermined number of individuals.


Mission Community Hospital is a health care provider offering a full range of medical, surgical, psychiatric, and emergency room services. Founded in 1923, Mission Community Hospital prides itself as the oldest hospital in the San Fernando Valley of California. Today, Mission Community Hospital is owned and operated by its parent company, Deanco Healthcare, LLC. Headquartered in Panorama City, California, Mission Community Hospital is a two-campus care center with a 60-bed inpatient unit, as well as a newly built 145-bed facility.


On May 1, 2023, Mission Community Hospital discovered that it had experienced a data breach in which the sensitive personal information in its systems may have been accessed and acquired. While much information surrounding the data breach remains unknown, on May 31, 2023, a ransomware group posted several files online as proof of the attack, including files from Mission Community Hospital’s imaging system, employee-related files, and financial reports and files. At present, Mission Community Hospital has not publicly confirmed that they were the victim of a cyberattack.
