About Us

Medical professionals typically believe they get better service and outcomes from a company they own, rather than from a giant, national firm owned by stockholders. But they also want the big ideas, the expertise of national leaders, and the financial strength of an established company. Alterna provides physicians and groups looking for alternative risk financing the best of both worlds-ownership, focused expertise, and creative solutions to managing risk.

Alterna has offices in Florida, Nevada, Vermont, Washington, and West Virginia and is a wholly owned subsidiary of Physicians Insurance A Mutual Company.
