Several times a year, Prairiewoods serves as a site for the Institute of Spiritual Healing and Aromatherapy, which teaches classes in spiritual healing and aromatherapy. People from all walks of life, from nurses, chaplains, massage therapists to just people with an interest in healing, take a series of classes to to prepare them in the art of hands-on healing and anointing with essential oils. ISHA is based in the Denver, Colo., area and offers their courses throughout the U.S. The folks who come here spread out in our conference room, lodge in our guesthouse and enjoy two-to-three days of classes.
