Ruane Clinical Research Group Inc.

Los Angeles carries 551 listings under public health clinic, more than anyone scrolls through in one sitting. Zip code is the fastest filter: several zips top out at 5 clinics each, so checking your own zip first beats paging through the full 551. Most listings have a phone number, 531 of them, so calling ahead about hours or eligibility works even for a bare-bones entry.

Fewer clinics list a website, 299 total, so skip nothing just because it lacks a link. Sponsored marks any paid placement on this page, and none exist in this category, so what you're browsing is unpurchased, plain directory order. If you run one of these clinics and see a wrong phone number or a missing site, you can claim the listing and update it yourself, which helps someone in Los Angeles find real info instead of a guess.
