Yes, Kaiser Permanente, one of the most hated HMOs in the United States. It's the health plan that's so bad, every American who has a choice runs screaming to another insurer - ANY other insurer - and yet they still annihilated the NHS in every category.
That's like managing to find a company whose finances make Enron look like saints.
That's a frightening, yet sobering, thought. Thanks be to god, that we do not have a government health care system, yet.
