Peter J. D'Adamo, ND, MIFHI

"I am afraid that Peter's merits are not estimated enough in the scientific world. Therefore it seems to me necessary, not only to promote his concept here in Europe, but also to tell him that I acknowledge him as one of the most creative scientists in the Western world."

-Professor Gerhard Uhlenbruck, PhD, MD

"Dr. Peter D'Adamo is a giant in the field of naturopathic and integrative medicine, and he has made transformational changes in the way thousands of doctors treat their patients. He has taught them to better manage and reduce patient's risk for various chronic health conditions."

- David Brady, ND, DC, Vice Provost for Health Sciences, University of Bridgeport
