I live in South Katy and still drive down to Ryan Newton in Greatwood. Been seeing him for 10 years. Really honest guy, good adjustments, and never have a problem seeing him on short notice.
Whatever you do, DO NOT go to Lambert Collins at Lifestyle Chiropractic on Cinco Ranch. Gave him a shot for a few months because he's so close to home, but he's just a snake oil salesman.
And if it's simply a quick adjustment to get right try a Joint location. No appointment needed, in and out quickly, and good adjustments. I started going to The Joint on Bunker Hill/I-10 when I realized it was cheaper, easier, and just effective as seeing a regular chiro.
We will just have to agree to disagree. While there are a large number who only try to sell you this and that, there is some benefit to what they do, if it's done right. Do they cure cancer, of course not, but there is some validity to proper chiropractic in the proper situation. And this is coming from a pharmacist.
