Jeff Garf first learned about Dr. Rife and his healing technology in 1987. His 19-year-old daughter was diagnosed with leukemia and died in 1999. He purchased one of these instruments to try and help her. He found that none of the machines or frequencies used in any of these machines matched Dr. Rife’s machine or original frequencies. He determined to find out why. After ten years of extensive investigation, he was able to find out how the machines worked and reconcile all the devices and the different frequencies they used.
