What NORCAL Mutual Insurance Company does
NORCAL Mutual Insurance Company was a California-based medical malpractice insurer founded in 1975, providing professional liability coverage to physicians, surgeons, and healthcare practices for nearly 50 years. The company historically operated as a policyholder-owned mutual insurance structure, distributing coverage through independent insurance agents and brokers specializing in medical malpractice and generating revenue primarily through recurring insurance premiums tied to specialty, claims history, and geographic risk factors. NORCAL's footprint was concentrated in the California market, with a correspondence address in Mechanicsburg, Pennsylvania, and a headcount of 251–500 employees.
In May 2021, NORCAL underwent a regulatory-supervised demutualization under the California Insurance Code and California Department of Insurance oversight, converting from a mutual insurance company into NORCAL Insurance Company, which was simultaneously acquired by ProAssurance Corporation. Eligible policyholders received Contribution Certificates — long-term interest-bearing securities maturing in 2031 at 3.0% per annum, administered by Computershare Investor Services LLC — in exchange for their mutual ownership interests. ProAssurance was subsequently acquired by The Doctors Company (TDC Group) on June 26, 2026, making TDC the ultimate parent of NORCAL Insurance Company. Under TDC, NORCAL's physician and healthcare professional customer base gains access to a substantially broader product suite spanning D&O, E&O, EPLI, property and general liability, workers' compensation, telehealth coverage, and health and disability lines — well beyond NORCAL's original medical malpractice focus. As of the latest available information, NORCAL Insurance Company continues to exist as a subsidiary within the TDC Group structure.
