Dr. Jeanne Petan, PhD., utilizes Electrodermal Screening (EDS) developed 50 years ago in Germany, which has now been used by 100,000 health care practitioners around the world. Goldberg states, “I am an instrument-rated pilot, and to use the vernacular, I consider any practitioners not using EDS as “flying blind”. Anyone who is taking supplements, especially individuals with health problems, should have their foods, vitamins, minerals, herbs, homeopathic, etc., tested to make sure that they are actually biologically necessary and beneficial.”
