Information about the Mentorship with Jill and Neil sessions…

We are excited about our collaboration with Dr. Jill Crista, author of the bestselling book, Break the Mold, and the newly released, A Light in the Dark for PANDAS & PANS. This mentorship group formed after a workshop given in April 2021 on Mold Toxicity with Drs. Crista and Nathan. After attending the “live” workshop attendees were invited to an ongoing Mentorship with Jill and Neil that meets every two months on a Saturday from 9 am – 12 pm PDT. Participants are invited to present patient cases to be reviewed and discussed from both the MD and ND perspective. All with prescriptive authority are invited to join the discussion. The cost is $100 per session. We hold the sessions via Zoom and send recordings afterwards to all who registered. If you are unable to attend the “live” discussion, you can purchase the video recordings and view at your convenience.

A few words from Dr. Nathan…

We also have an active listserv dedicated to this group. Members can discuss patients’ health concerns and gain valuable suggestions and insights from the experience that colleagues bring to this forum. We are so pleased with the camaraderie and knowledge base offered in this group.

To ensure that everyone “comes to the table” with the same knowledge base, we do ask that you purchase and review the videos of one of the previous workshops: Comprehensive Mold Toxicity Workshop, 2021, Advanced Chronic Inflammatory Illness, 2022, All Day Workshop, 2023, and An In-depth Exploration of Chronic Illnesses, 2024.  If you have taken Dr. Crista’s course, this will also meet the criteria.

For more information, please contact us at askdrnathan@gmail.com. We look forward to hearing from you.



Testimonials from members of the Mentorship

Dr. Nathan is the world’s foremost authority on treating complex chronic illness.
I will forever be grateful for his guidance in teaching me to help even the
most complex and chronically ill patients. Mentorship with Dr. Nathan
has transformed how I approach medicine and has allowed me to heal
patients that I previously thought were incurable. His lessons and wisdom
come to my mind every single day I work with patients.

Dr. Joe Mather, MD, MPH&TM
Medical Director Ruscio Institute for Functional Medicine

Dr. Nathan has impacted the lives of my patients, my career, and my own health
journey. He is a gifted teacher who communicates with great clarity. He provides
detailed, yet practical approaches to evaluate and treat the most complex of patients.
Dr. Nathan exemplifies compassion and honoring the patient’s autonomy.
He also models and encourages self-care to those he mentors.

Courtney Snyder, MD
Child & Adult Holistic Psychiatry/Functional & Environmental Psychiatry

I am so fortunate to have Dr. Nathan’s mentoring webinars and counsel to help give me the extra pairof “eyes and ears” I need to see more clearly how to help my patients. I find Dr. Nathan has atremendous amount of real world experience that every physician who practices in the fieldof functional medicine can benefit from.

Dean Mitchell, MD
Adjunct Clinical Assistant Professor Touro College of Osteopathic Medicine

I am beyond grateful that I found Dr. Nathan as early in my career as I did, and that he generously shared his knowledge. I remember listening to him lecture at my very first ILADS and thinking “this guy sees the same patients as I do” and proceeded to take every opportunity to learn from him that I could find. It was a huge relief because the other doctors described cases of patients taking huge amounts of medications and getting better – those protocols would have prostrated the people I was seeing in my office. I didn’t know much about Lyme, nothing about coinfections, hadn’t heard of mold, and was busy turning over rocks in the MTHFR space looking for answers. Finding answers that work for my sensitive patients is still a full time pursuit, but thanks to to Dr. Nathan’s work and willingness to share, I have been better able to help the thousands of sensitive, wounded and confused people who have reached out to me for medical care.


Anne Van Courvering, ND, LMT

I have been in the mentorship for several years. I especially appreciate the focus on the sensitive patient with specific guidance for this growing subset of patients. The listserv allows great input and conversations from everyone in the mentorship, with input by both Dr. Nathan and Dr. Crista as well.This group is my “go to” for questions and advice on tough patients.

Clemma Nash, MD
Functional Medicine, Board Certified in Family & Integrative Medicine

I am a holistic adult and child psychiatrist practicing in the Boston area. Over time it has become clear that many of the patients who consult with me who have not been helped by conventional psychiatry are actually suffering from mast cell activation and illness caused by mycotoxins. I have learned to recognize and treat these conditions through the skilled mentorship of Dr. Neil Nathan. He has a wealth of experience and has been unfailingly responsive to work with him, which as allowed me to be more effective in my practice with complex patients

Judy Tsafrir, MD

Challenging cases which don’t flow smoothly may raise multiple intellectual and emotional issues for the physician causing self-doubt and clinical decision-making anxiety: Have I got it wrong and am I missing something here? The mentoring process helped me towards a more considered perspective on the treatment of complex illness, which always was positive and encouraging to stretch my skills, but without ever feeling patronized. I am a much better doctor from what I have learned, with a diagnostic road-map which really improves the doctor-patient mutual trust and partnership.

Dr. Patrick Magovern
Drummartin Clinic

Neil Nathan’s mentorship program has been on of the most outstanding and impactful trainings in my entire professional career. In two years, I went from having little understanding of how to diagnose and treat complex and severe mold-impacted patients, to gaining a proficiency that has allowed me to dramatically improve the lives of my pediatric patients. Neil Nathan is the most generous and wise teacher any persona can ask for.

Pejman Katiraei, DO
Wholistic Kids and Families, Wholistic Minds

Mentoring with Dr. Neil Nathan was a game changer for my practice. His methodical, practical approach to managing complex, chronic conditions is highly effective for a population of people whoare often failed by both traditional and functional healthcare. He is also one of the rare practitioners who is able to combine rigorous scientific understanding with deep empathy and intuition, all of which are needed in working with people with extreme sensitivities.

Beth O’Hara, FN
Functional Naturopath/Mast Cell Activation and Histamine Specialist

When I hit a plateau in helping my dementia patients afflicted with mycotoxin illness, it was extremely helpful to become part of Dr. Nathan’s mentorship group. His support over the past 4 years has been priceless, helping me to establish a framework, and troubleshoot cases, which has been instrumental in getting patients better.Dr. Nathan is heart centered and addresses all his mentees without judgement, meeting them wherever they are at in their practices.
