A couple of years ago, after some search, I found Paul Gruber's sample video and loved it.
I have greatly benefitted from videos and live sessions. He has extraordinary ability to identify your issues and teach you in a way that change your conversation. I highly recommend him to anyone who need help in this area. He is amazing!
