Diplomate, American Board of Internal Medicine
Member, HHS Tick-Borne Disease Working Group Co-chair, HHS Other Tick-Borne Diseases and Co-infections Medical Director, Hudson Valley Healing Arts Center, Hyde Park, NY Author of two best-selling Lyme disease books

Richard Horowitz, MD, is a board-certified internist in private practice in Hyde Park, NY. He is the medical director of the Hudson Valley Healing Arts Center, an integrative medical center that combines classical and com- plementary approaches to the treatment of Lyme disease and other tick-borne disorders. Dr. Horowitz has pro- vided clinical preceptorships for the past two decades for practitioners nationwide. He has treated over 13,000 chronic Lyme disease patients and is a founding member of the International Lyme and Associated Diseases Soci- ety (ILADS) and past president of the International Lyme and Associated Diseases Educational Foundation (ILADEF). In his New York Times best-selling book “Why Can’t I Get Better? Solving the Mystery of Lyme and Chronic Disease,” Dr. Horowitz explains his full diagnostic and treatment approach to patients who have complex tick-borne illnesses. Dr. Horowitz’s second book, another national best-seller, is titled “How Can I Get Better? An Action Plan for Treating Resistant Lyme and Chronic Disease.” Dr. Horowitz is a popular guest on TV and radio, and he lectures nationally and internationally. He is a member of the HHS Tick-Borne Disease Working Group, which recently provided Congress with recommendations for the diagnosis and treatment of tick-borne disorders.

BOOK DESCRIPTION: Dr. Richard Horowitz released his second book, “How Can I Get Better? An Action Plan for Treating Resistant Lyme and Chronic Disease,” through St. Martin’s Press in February 2017, and it has become a national best- seller. This edition contains important scientific updates on Lyme, other Borrelia species, associated co-infections (such as Babesia, Bartonella, rickettsial infections and tularemia) with a new chapter on pulsing and “persisters.” This chapter explains in detail the science on biofilms and persister formation for Borrelia, and it also ex- plains how to use Dapsone and other “persister” protocols in individuals failing tra- ditional treatments. “How Can I Get Better?” also contains updates on the MSIDS model and how it impacts many chronic diseases (such as Alzheimer’s, autism, and ALS) plus a detailed addendum for healthcare practitioners on how to prescribe both classical and integrative therapies to help patients who are still chronically ill. The new ILADS guidelines are also highlighted with over 800 scientific references sup- porting diagnostic and therapeutic interventions. The book is available for order at Amazon.

Neil Nathan, MD has been practicing medicine for 48 years, and 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 ISEAI. He 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 has hosted an internationally syndicated radio program/podcast on Voice America called The Cutting Edge of Health and Wellness Today. He has been working to bring an awareness that mold toxicity is a major contributing factor for patients with chronic illness and lectures internationally on this subject which led to the publication of his book, Mold and Mycotoxins: Current Evaluation and Treatment, 2016 and now to his most recent book Toxic: Heal Your Body from Mold Toxicity, Lyme Disease, Mul- tiple Chemical Sensitivities and Chronic Environmental Illness.

His current medical practice is the Redwood Valley Clinic in Northern California. He can be contacted most easily through his website www.neilnathanmd.com, through which consultations are available.

Dr. Nathan has been treating chronic complex medical illnesses for 25 years now, and Lyme disease for the past 15 years. As his practice has evolved, he finds himself increasingly treating the patients who have become so sensitive and toxic that they can no longer tolerate their usual treatments, and his major current interest is in finding unique ways of helping them to recover.

A Comprehensive & Practical Review of Mold Toxicity and its Complications

with Neil Nathan MD & Jill Crista ND


A videotape of this Workshop is now available.
If you are interesting in receiving the recording, please contact us at:


Please join us this April for a truly in-depth and practical review of Mold toxicity and its complications. 

This workshop is designed for medical practitioners who have MD, DO, ND, NP or PA certification. In this workshop, we will be discussing the presentation of mold toxicity, how to test patients and then step-by-step treatment programs for patients who have a robust constitution and for those who have become more sensitive. We will delve into the finer points of the entire detoxification process, and then dig into the conditions frequently triggered by mold toxicity that often present stumbling blocks in treatment: mast cell activation, limbic dysfunction and vagal nerve dysfunction.

We will include a discussion of common comorbidities with mold toxicity including Lyme disease, Heavy Metal toxicity, and Endocrine Disruption (among others).

Workshop Pricing: $300 (USD)

Register via email by contacting Dr. Neil Nathan at: askdrnathan@gmail.com

Cancellation policy:  You may cancel your registration up to two weeks prior to the workshop, minus a $25 administration fee.

Hosted by Dr. Rebecca Risk

Episode Description

Millions of people have sought medical care, and found that they have hit a wall with their doctor even though they feel very sick. There is an epidemic of tick born illnesses (Lyme Disease), mold exposure, chemicals and other toxins that are causing illness. Unfortunately, these illnesses are falling through the cracks in our health care system. Dr. Neil Nathan is discussing his book “Toxic”, which is a easy to read, but thorough journey through these toxic illnesses.

More about Toxic…Heal Your Body

Now available as an audiobook on Amazon.com


Millions of people are suffering from chronic illnesses that, unbeknownst to them, are caused by exposure to mold, Lyme disease, other infectious agents, and other environmental toxins. Millions. Because the symptoms of these illnesses are so varied and unusual, many of these individuals have sought medical care only to be dismissed, as if what they are experiencing is “in their head.” Many (if not most) have tried to tough it out and continue to function without hope of improvement. Unfortunately, their illnesses are very real. Toxic is a book of hope for these individuals, their loved ones, and the physicians who provide their care. Over many years of helping thousands of patients recover their health (even after their previous doctors had given up on them), Dr. Neil Nathan has come to understand some of the most common causes for these debilitating illnesses, which allows for the utilization of more precise and effective forms of treatment.
The goal of this book is to shed light on these complex illnesses so that suffering patients and their families can get the help they so desperately need. In the book, you will find:

  • Information about how extreme sensitivity and toxicity develop in the body, how they differ, and how they often overlap
  • Detailed descriptions of each of the four major causes of hypersensitivity and toxicity: mold, Bartonella (a co-infection of Lyme disease), mast cell activation, and porphyria and carbon monoxide poisoning
  • An outline of the cell danger response, a revolutionary model developed by Dr. Robert Naviaux that explains how the body essentially gets “stuck” fighting a threat even after the danger has passed
  • A system-by-system plan for “rebooting” the body to break the cycle of illness and allow healing to begin
  • Information about coping with stress and embracing an emotional and/or spiritual awakening on a path to wellness

Dr. Nathan’s wisdom, clinical acumen, kindness, compassion, careful listening to his patients, and lifetime of experience have sparked medical insights that have the power to inspire a new generation of physicians.”

                      —Robert Naviaux, MD, PhD

                          from the foreword

Dr. Neil Nathan’s book, Toxic—Heal Your Body, fills a critical niche in the evaluation and treatment of patients with mold illness, tick-borne illnesses, and chemical sensitivities.  This is one of the most difficult, and widely misunderstood, areas of medicine, yet critical to so many patients in need. Dr. Nathan brings a clinical experience and expertise that is unmatched when it comes to multiple chemical sensitivities.  If you are a patient with these problems or a practitioner caring for such patients, this is the most important book you will read this year.

Mold and Mycotoxins

“Mold & Mycotoxins: Current Evaluation and Treatment 2016”

This book is intended to help both medical practitioners and patients to understand our growing understanding of how mold toxicity and mycotoxins can profoundly affect health. It provides an overview of how mycotoxins create an unrelenting inflammatory process that influences the immune system, nervous system, endocrine system, gastrointestinal system, emotions and pain. It reviews the current approaches to diagnosis and treatment.


On Hope and Healing: For Those Who Have Fallen Through the Medical Cracks is a resource book offering the latest information on a range of illnesses that most family practitioners are unequipped to diagnose or treat effectively. Written in nontechnical language, On Hope and Healing also offers clear, readable explanations for the causes and cures of today’s onslaught of complex/chronic illnesses. Physicians and patients alike will benefit from this book.
