Once in a while, I stumble across a treasure trove of expertise.  The NOI Group mostly provides training and seminars to physical therapists, but with a little sleuthing,  this listing will help you find a top-notch practitioner in your corner of the world.  Use Google to do the rest.

I love it when I get an email from a trainer who really gets it!

Nicola Folino is a 46-year-old mother of two, a former low back pain sufferer and a personal trainer.  Due to her own issues with crippling lower back pain, that at times prevented her from engaging in her love for fitness, she embarked on a mission to try to fix the problem.

From Nicola:

"I spoke with doctors and chiropractors and read and read and read some more! I eventually discovered Stuart McGill and it changed my world. I read all of his books, watched his videos, attended his seminars and I am waiting to sign up for his "McGill Certification Program" which is coming soon!  I have "fixed" my own back pain and enjoy fitness full time again!  I have developed a Personal Training Program based on Stuart McGill's methods for my clients with low back pain and have had great success!  I also just invested in one of the spine models from Dynamic Disc Designs which is a phenomenal teaching tool."

Dr. Stuart McGill is a professor of biomechanics at the University of Waterloo in Ontario, Canada. He frequently advises governments, corporations, and elite athletes and athletic teams when it comes to difficult back cases. In his laboratory at the University of Waterloo, experts test out products and recommendations, and only the best make it to his website, BackFitPro, a repository of back pain prevention and rehabilitation information.
