They volunteered Reiki at Ground Zero  after 9/11. They were pioneers in introducing Reiki in the operating rooms of New York Presbyterian/ Columbia University Medical Center, during breast cancer surgeries. Their work together was the precursor of both Raven Keyes Medical International, founded to train  Certified Medical Reiki Masters, and Medical Reiki Works.
