About Immersion Health

Immersion Health was started as an intensive naturopathic oncology clinic. Dr. Nigh develops comprehensive and intensive treatment programs for all types and stages of cancer. 


The cancer treatment approach at Immersion Health is unique, recognizing cancer as a metabolic disease. At Immersion Health we are delivering therapies that address all aspects of health and vitality, because long-term success against cancer depends on a strong immune system, low inflammation, ongoing detoxification, lifelong nutritional strategies, stress management, physical activity and much more. Immersion Health brings this all together into individualized treatment plans that optimize every individual's potential for recovery and ongoing wellness.


In addition to cancer treatment, Dr. Nigh brings these same metabolic therapies into the treatment of many patients with difficult chronic conditions such as mold-related illness, Lyme disease, chronic fatigue/immune dysregulation syndrome (CFIDS), fibromyalgia, and others. In practice for over 17 years, he works collaboratively with clinic co-owner and nutrition therapist Maria Zilka. They have had great success treating patients with thyroid disorders, autoimmune diseases, diabetes, hypertension and heart disease, Crohn's disease and ulcerative colitis, menopausal symptoms and much more.



Dr. Nigh is a naturopathic physician and licensed acupuncturist, graduating from the National College of Natural Medicine in 2001. He has a specialty in naturopathic oncology, and through years of research has developed a unique approach to cancer treatment. Read More...

Maria Zilka received her Nutrition Therapist certification in 2008 and has been working since that time in collaboration with Dr. Nigh. She is responsible for patient education and implementation of a wide range of therapeutic diets used with patients of Immersion Health. Maria is one of the most experienced and knowledgeable practitioners in the country regarding all aspects of the calorie restricted ketogenic diet and its implementation with cancer patients. In addition to that, Maria literally wrote the cookbook on implementation of the Low Sulfur Protocol that she and Dr. Nigh developed and have used to great success with hundreds of patients.
