Dr. Greenberg began his premedical studies at the University of California in Santa Cruz and remained a first responder/paramedic throughout the 1980's. Disillusioned by mainstream medicine, he attended the National College of Naturopathic Medicine (NCNM) in Portland, Oregon. While attending NCNM, he treated a severe poison oak rash with homeopathy and had a instantaneous response. This inspired an intensive study of this 200 year old art and science. He graduated in 1989. He began his practice in Kona (Big Island, Hawaii) but by mid-1990 relocated to Kauai. Since then Dr. Greenberg has faithfully served the Kauai island residents utilizing physical medicine (manipulative therapy, craniosacral therapy, myofascial trigger point injections) and classical homeopathy primarily. However, after a few years in practice Dr. Greenberg began integrating applied kinesiology with nutritional and herbal therapies as well.

Over almost the past 20 years, Dr. Greenberg sees routine as well as difficult and complex cases from industrial and auto accident injuries to the private sector that the medical establishment had given up on. Miles strives to engender independence in patients and to improve the quality of their lives. He also freely refers within the Natural Health Clinic and as well to appropriate specialists. Naturopathic medicine strives to follow the Hippocratic oath of "first do no harm" and not be confined by ideology or dogma. Our patients deserve to be treated with dignity and with what works best regardless if it's from nature or science.
