Cannot understate how unhappy I've been with GHC. Providers themselves are great, but if you're on an HMO and need any services other than primary care, forget it. My main provider is booking 4 months out. I've been fighting with their mental health department for a year and a half now to get basic services that were no problem with my former insurer. My roommate saw one of their chiropractors and after adjustment he told her, "well, come back whenever it hurts again" -- despite the fact that she has scoliosis and ongoing back problems. They patch you up for the short-term and then make you scrape and beg for service once things get urgent again. They seem to have a philosophy as an insurer that discourages ongoing or preventative care. Just... absolutely terrible.
