Neil Nathan, MD

Neil Nathan, MD, has been practicing medicine for over 50 years. He has been board-certified in Family Practice and Pain Management and is a Founding Diplomate of the American Board of Integrative Holistic Medicine and a Founding Diplomate of the International Society for Environmentally Acquired Illness (ISEAI). 

Dr. Nathan has written several books, including Healing is Possible: New Hope for Chronic Fatigue, Fibromyalgia, Persistent Pain, and Other Chronic Illnesses and On Hope and Healing: For Those Who Have Fallen Through the Medical Cracks. He also hosted the internationally syndicated VoiceAmerica radio program and podcast The Cutting Edge of Health and Wellness Today. 

Dr. Nathan has worked to bring awareness to mold toxicity as a major contributing factor for patients with chronic illness and lectures internationally on the subject. This work led to the publication of his ebook Mold and Mycotoxins: Current Evaluation and Treatment, originally published in 2016 and updated in 2022, followed by his best-selling book Toxic: Heal Your Body from Mold Toxicity, Lyme Disease, Multiple Chemical Sensitivities, and Chronic Environmental Illness. The second edition of Toxic was released in 2025. In 2021, he published Energetic Diagnosis, a discussion of the value of intuition and energetic devices as aids to both diagnosis and treatment of medical illness. The Sensitive Patient’s Healing Guide was published in 2024. 

Dr. Nathan has been treating complex chronic medical illnesses for 30 years and Lyme disease for the past 20 years. As his practice has evolved, he has increasingly focused on patients who have become so sensitive and toxic that they can no longer tolerate their usual treatments, with a major interest in finding unique ways to help them recover. 

He currently provides mentorship in the treatment of chronic inflammatory illness to approximately 200 physicians with Dr. Marie Matheson.
