Dr. Lewis Heller, is not just a hypnosis doctor he has his medical degree and is very patient when speaking to him. Actually he has given me CD' to play back at a later time after his session to keep me on track. His voice is soothing making your anxiety disappear allowing your body to heal. Once while in the hospital after my surgery he did a session with me, which allowed my pain to lessen giving me the strength to not have to depend on drugs to keep the pain level to a minimum.
