Watch out... The place you are going to might be great but chiropractic adjustments are essentially a sham and a bit dangerous... often they will find things that are not even wrong with you... hopefully yours is good though?
I'm well aware of chiropractic practices being a huge sham. However, this place also touts itself as a sports massage therapy place. The workers and professionals there are all relatively young, so that makes me a little more comfortable. But if they have me doing retarded back cracks and stuff, I'll be out of there in no time.
If they don't directly address postural issues that I KNOW I have, without me telling them, I'm also out of there. My left upper trap is overactive, for example. My lats are very tight. If they don't do this test:

Or something like this:

So I guess I have a way of assessing their assessing skills
