Tim Grady’s Corner
My good friend and former USP colleague Tim Grady and I frequently challenged each other and wrote articles addressing positions as the USP evolved new standards. Some of these articles were never published and the web now
These articles present Tim’s views which may not be those of the USP or me but getting them out there may stir some thoughts and that is good.
I hope you enjoy his articles and I’m sure there will be others.
