I have two David Dorian-Ross Tai Chi dvd's. I like him. My kids and husband hate his voice, but I find it relaxing. LOL for years I did his a.m. practice every morning, and found it a great relaxing way to get moving in the morning. I live in kansas out in the middle of no where so there was no local classes that is why I chose the dvd. about 6 months ago I moved to a much larger town (a population of 3,000 people) and just read in the paper they have monthly Tai Chi classes at a local gym. I am pretty excited and plan to sign up for them this summer!
