Andrieh Vitimus is the only person that has ever been able to get me to quiet my mind, and believe me, I've tried everything. Not only that, but he taught me how to do it myself. I highly recommend his classes. They are fun and informative. He's an effective and patient teacher, willing to assist you until you've grasped what you need to. Regardless of your path, you will always get something out of every class.
