Yes! The KP HMO has history with but is not owned by the Kaiser industrial companies. It was essentially setup by Sidney Garfield at the behest of Henry Kaiser and the help of FDR to treat workers at the Kaiser shipyards, hence the name. It's a not for profit organization completely distinct from other Kaiser organizations. Funny enough I'm pretty sure at $79 billion yearly, it grosses more than it's industrial namesakes.
