I disagree with you completely! Dr. Rind really helped me after I was in a car accident. I had whiplash and in 6 visits I was 1000 times better and my neck was able to turn. He helped me in many other areas too like with my spine, infection, and hormones. He is one of the best doctors I have ever gone too.
I also took a course he gave once and it was fabulous. I still use the techniques I had learned from him to this day.
Now his office does NOT bill your insurance. You have to take care of that yourself...but you should have gone into it knowing that. I did. Half of the things he does there are simply not covered by insurance and that is a problem for some people and can be frustrating because when you are sick you want more things to be covered....but you can call your insurance company like I do before anything is done to ask if it is covered or not. I grew up with alternative medicine so sometimes people who haven't don't know what to expect and that is where I think some of your frustration is sourced.
He healed me where no other doc did. Did I find the long waits in his office frustrating? Yep. But if you have something serious that needs attention and other docs just give you a pill to get rid of you, then you are better off seeing him as he will get you healthier.
