I want to tell you how kind and professional Ellen Stern was when I first had a biofeedback session. I work very hard and my colon had been bleeding for years. I feel that biofeedback was one of the factors, that has helped me heal. I also get a power house full of energy from the biofeedback. I was so amazed at the machine knowing, where and what I harbor in my mental and physical body. WOW, is this machine alive, so cool. Thanks so much, Ellen! I am sure I need a tune up now! You’re the Best.
