"Really should be honest about hours open for out of towners. Definitely closed well before 1130 for lunch. No one should have to sit in a hot parking lot for 2 hours waiting to be checked in to wait god only knows how long to be seen."

LocalityBiz user review

"I’ve consistently had a frustrating experience with CHI billing. Simple payments take 25–30 minutes or more, and verifying accounts for my husband or child is unnecessarily complicated."

LocalityBiz user review

"ER doc treated me in street clothes? Also almost every ER doctor here has horrible bedside manner."
