CranioSacral therapy was first developed in the 1920’s by Dr. William Sutherland, who discovered the gentle rhythm of the cerebral spinal fluid which he called the Primary Respiratory Mechanism. After extensive investigation into the movements of the cranial bones, he developed Cranial Osteopathy. In the 1970’s, Sutherland’s work was researched and scientifically validated by a team led by Dr. John Upledger, D.O. at Michigan State University. Subsequently, Dr. Upledger went on to develop a method of training CranioSacral therapists and created the Upledger Institute. Dr. Maureen Schwehr, a naturopathic physician, was trained in the Upledger tradition at the Integrative Bodywork Institute by Dr. Nancy Soliven, DC, MD who was Team Leader at the Upledger Brain and Spinal Cord Center. Dr. Schwehr has taught CranioSacral therapy at Bastyr University in Seattle, and the Cortiva Institute, Desert Institute of the Healing Arts in Tucson. She currently conducts classes in Tucson and Minneapolis/St. Paul.
