Greg Nigh

Clinic Medical Director, Naturopath, Oncologist, Licensed Acupunturist

Dr. Greg Nigh co-founded Immersion Health in 2014 with Maria Zilka, NTP. Dr. Nigh is a graduate of the National College of Natural Medicine, where he completed both the Naturopathic Doctor (ND) program and the Master of Science in Oriental Medicine (MSOM) program concurrently. Prior to studying naturopathic medicine, he attended the University of Notre Dame, where he received his Bachelor’s in English and then completed a Master of Humanities program at Arizona State University.

Prior to his work at Immersion Health, Dr. Nigh co-founded Nature Cures Clinic in 2001. It was during his early years of work there that he developed his interest and passion for researching and implementing alternative cancer therapies. It was also at Nature Cures Clinic that Dr. Nigh began collaboration with Maria Zilka, which spanned his last 5 years of work there.

Dr. Nigh is widely respected in the naturopathic profession. He has spoken several times at the annual convention of the American Association of Naturopathic Physicians on topics as diverse as naturopathic treatment of strokes, the use of hypnosis in clinical practice, and the use of energy medicine in the treatment of anxiety and depression.  He has also spoken at the national conference of the Oncology Association of Naturopathic Physicians on cancer cell metabolism.

Dr. Nigh is a prolific reader, researcher and writer. He contributed a chapter to the upcoming two-volume Foundations of Naturopathic Medicine textbook, and has published articles, book reviews, essays, and even short stories. Topics of deep interest and ongoing exploration range from evolutionary biology, epigenetics and the politics of science, to cosmology, metaphysics, zen philosophy, current events and, of course, the biology and physiology of cancer.

Dr. Nigh (he prefers “Greg”) works very hard to be easily accessible to every patient in the treatment program. He spends a great deal of time with every patient, always attempting to have a complete understanding of each individual, their personal circumstances and challenges, and the best strategy for implementing the appropriate treatment program.
