1995 CHIRO 100 CHARLIE AND MARK WASH DC — 1995 Mark and Charlie DuBois, Chiropractic 100th Birthday

Protomorphogen (PMG) Research

Advancing the modern understanding of PMGs and their clinical application in immune-mediated reactions — one of Dr. Royal Lee’s most significant contributions.

Autoimmunity as Disease Progression

Reintroducing Dr. Royal Lee’s concept that autoimmunity represents a stage and phase of disease progression rather than a primary disease itself — a framework with significant clinical implications.

Cataplex B-Core Development

Conceiving of, formulating, and contributing to the development of Cataplex B-Core, one of the most successful contemporary Standard Process formulations currently in clinical use. Based on original findings of Royal Lee, powerful but rarely configured naturally occurring B vitamins register rapid, profound, and measurable effects on the body.

Heart Sound Recorder (“Reincarnation” of the Endocardiograph)

Preserving the knowledge of the “extinct” Endocardiograph and helping guide its modernization — Dr. Royal Lee’s instrument for evaluating heart sounds (auscultation) — now developed as a digital Heart Sound Recorder. A profoundly accurate measurement of nutritional status of the heart.

Webinar Wednesday

For 30 years, Mark Anderson hosted his annual Back to School for Doctors seminars in Denver — the largest gathering of its kind, bringing doctors together to share the vision, knowledge, and camaraderie of these content-rich, often life-altering classes. The mission continues with the same passion: preserving and building upon the timeless works of Dr. Royal Lee by educating doctors in the philosophy, knowledge, and applications of Dr. Lee's unique and powerful formulas. Truth never fades. Join Mark online twice monthly — on the first and third Wednesday of each month — for Nutritional Therapeutics training sessions inspired by the Royal Lee Legacy.
