Cleveland Regional Medical Center is a hospital that works to help you ... the patient. They have a sleep center, a psychriatric center, and other divisions like most hospitals. Most area doctors recommend their patients to go here for bloodwork, sleep tests, and the like. Although their sleep lab is not accredited, they say it will be within a year.
Beware of your bills, though. Be sure to check them really well, as I have found errors in my statements. They are easy to talk with on the phone, but if you find errors, the proof needs to be really good proof or they won't correct the errors. The emergency room there isn't that good because every time I go, I wait for hours on end.
