Dr Sandeep Gupta, MBBS (MD)

Dr Gupta is a vocationally registered general practitioner who runs an integrative medicine clinic (Lotus Holistic Medicine) on the Sunshine Coast, Australia. His main passion relates to finding the underlying causes and innovated approaches to managing chronic illness. Dr Gupta graduated from medical school at the University of Queensland 1999 before working in the hospital system for ten years. After a brush with illness led him to embracing a more holistic model of patient care his initial approach was heavily dietary and nutritionally oriented but later he came to know of mold-related illness, tick-borne disease and heavy metal toxicity. He has now treated over 10,000 patients with these complex chronic illnesses and is passionate to share his knowledge with other practitioners keen to add this to their tool kit. In 2017 he established the Lotus Institute of Holistic Health which has seen the launch of the online courses Mold Illness Made Simple, EMFs Made Simple and Mast Cells Made Simple.
Dr Amy Derksen, ND

Dr Amy is a former competitive athelete and Naturopathic Physician with a full scope of practice in Washington State (Holistic Healing Arts). She did her undergraduate studies in biochemistry and she was the first physician to do her medical postgraduate training with Dr Dietrich Klinghardt, MD, PhD after graduation in 2003 and taught ART courses for his academy for 10 years. She specializes in working with both autism and chronically ill patients, including Lyme disease, mold-related illness and MCAS. She has additional training in PANS/PANDAS, ILADS, mold-related illness, genetics/methylation, LDA/LDI allergy treatments, peptide therapies and BHRT. Dr Amy is someone who struggles with an autoimmune disease and who has recovered from post-COVID symptoms. She became particularly interested in mold illness from personal experience via exposure to a water-damaged home in college that triggred thyroid issues and then later had water intrusion in her medical practice that led to evacuation and relocation.

In general Mold Illness Mastery has approximately 22 hours of video lecture content plus 2-3 hours of live Q&A. Each cohort may have a slight differences in total lecture/Q&A length.
Mold Illness Mastery uses a hybrid format with live and on-demand components:
- Live: 8 weeks of live Zoom sessions comprising key pre-recorded lessons plus a Q&A with both instructors. Duration: 2 hours per week (approximately).
- On-demand: All pre-recorded lessons, plus the Q&A recording, for that week will be available within 24 hours after the live session. Duration: 1-3 hours per week (approximately).
- Bonus modules: These can be watched on-demand at any time. Duration: 5.5 hours.
A student can choose to do a combination of live and on-demand, or if they can’t make the live sessions, on-demand only.
Mold Illness Mastery is a comprehensive practitioner level online course focused on mold-related illnesses, including chronic inflammatory response syndrome (CIRS), dampness and mold hypersensitivity syndrome (DMHS), sick building syndrome, mold toxicity, fungal colonization, and mycotoxicosis.
The Mastery Course Portal for students is:
(this is a different link than for the Made Simple courses)
Although primarily for health practitioners, members of the general public who are at an advanced level (ideally have studied one or more of the Made Simple courses) can enroll in a Mastery Course, however, they should not use the live Q&A for specific medical questions about their own health.
The Mastery Courses are advanced courses using a hybrid live and on-demand course format.
The Mastery Courses are aimed at health practitioners of all types including doctors, dentists, naturopaths, osteopaths, chiropractors, nutritionists, psychologists, other allied health practitioners and health coaches.
