My recent take on chiropractors:
We moved from one corner of Virginia last year up near another corner. I'd go to my wife's chiropractor once every five years or so if I was really out of whack. $25 per visit, as my insurance did not allow for chiropractic (uhh, thanks, Obama). Very down-home office, as suits the territory. Doctor was athletic and middle-aged hip, but it was a "Hi, Hon" medical office.
Move up here: High-tech office, more modalities, decompression rooms, paying more rent. My wife's on Medicare, but I asked about rates for no insurance:
$75 per visit. I gulped.
"But you can put down $1440 for the next 24 visits and we'll give you a discount." Uh, no thanks.
My wife was put on an original schedule of twice per week, and they scheduled 26 weeks in advance. My wife finally decided she was tired of going down there twice a week. On the next visit, we said, "Please switch to every two weeks." Counter girl is not impressed. She's taking all those paid appointments off the schedule.
She doesn't try to convince us of the benefits of continued treatment. The doctor doesn't come out for a second and say that's against original orders.
I'm sure they are doing some kind of good work. They also cheerfully treat their patients as ATMs, except when the plug is pulled.
