I've been using Dr. Pat Bona for a year now. She has a human practice as well in Blue Bell. She's just getting her website up for horses here:http://www.postureprep.com/
I can't wait to get one of her posture prep groomers. I've been making due with what I have, but it makes my hands hurt. It's so important to deal with the muscles at the same time as the joints and spine.
I also have been a client of Dr. Pat Bona's for just over a year. She is very well versed in biomechanics and has been doing a wonderful job on my sometimes-grumpy thoroughbred.
As a medical professional myself, I find her fantastic to deal with, and I've watched her interact with some of the younger clients in our barn just as easily.
We love Dr. Pat!!
