Health care branding

As a grad student, my health insurance provider is Gallagher Koster. That's what the printed materials and the website say, anyway. My card says UnitedHealthcare Insurance Company, with further logos from Signature Health Alliance, Beech Street, and Medco. Payment notices in the mail come from Klais & Co.

Now Gallagher Koster announces we can get dental insurance through United HealthCare Dental. When you go to their website to look up providers, you have to choose a plan name, and none of them (as far as I can tell) are mine. At least, I've ruled out the ones that have "Arizona" and "Dallas" in their names.

You know, in most businesses, brand recognition is considered a highly desirable thing. How else will the customer know to request Acme products? I guess in businesses where your customers hate you, they want to make sure they don't know your name.
