William D. Nelson, NMD, has been in continuous clinical practice since 1996, helping patients who feel lost, overwhelmed, or out of options finally understand what is happening in their bodies—and what to do next. As founder and medical director of Explore Health in Scottsdale, Arizona, Dr. Nelson has become the physician people are sent to when answers are unclear and progress has stalled.
Many patients arrive after years of specialists, imaging, labs, second opinions, and endless online research. Yet despite all the information, they remain stuck. That is because true healing is rarely about a single diagnosis. It requires seeing patterns—how genetics, inflammation, infection, structure, nervous system regulation, and lived experience intersect.
Dr. Nelson is known for his rare ability to combine advanced modern medicine with the insight of a true healer. Patients often describe him as part indigenous medicine man—sometimes referred to as a “Shaugoma”—and part relentless diagnostician in the spirit of Dr. House. He listens deeply, thinks critically, and explains complex physiology in a way patients can finally understand.
Explore Health specializes in complex chronic illness, including Ehlers-Danlos syndrome, ME/CFS, chronic viral illness such as EBV and CMV, Long COVID, autoimmune and inflammatory conditions, and difficult pain syndromes. Dr. Nelson also supports cancer patients using innovative, evidence-informed approaches including onco-genomic testing, repurposed medications, and European natural therapies such as mistletoe—often integrated alongside conventional care.
In regenerative orthopedics, Explore Health offers non-surgical solutions for back, hip, knee, shoulder, and nerve pain using advanced injection therapies, neural therapy, and biologic products including cord-blood–derived stem cell products, exosomes, and Wharton’s Jelly. These products are not FDA-approved drugs but are manufactured in compliance with FDA CFR standards and are designed to restore healthy cellular signaling—reducing inflammation, promoting blood supply, and supporting tissue repair.
Approximately half of Explore Health patients travel from outside Arizona to establish care, then continue with structured telemedicine follow-ups. When patients don’t know where to turn, they are often told the same thing: Go to Explore Health. They’ll help you figure it out.
WHY EXPLORE HEALTH IS DIFFERENT
Explore Health is not a protocol-driven clinic. It is a navigation center for people who feel stuck.
Dr. Nelson does not treat diagnoses in isolation—he treats systems. Symptoms are viewed as signals, not nuisances to suppress. Every plan begins with a simple question: Why is this person not healing?
Care at Explore Health integrates:
Root-cause evaluation rather than symptom masking
Advanced diagnostics combined with clinical pattern recognition
Structural, immune, metabolic, neurologic, and psycho-spiritual insight
Regenerative therapies focused on repair rather than suppression
Education so patients understand their bodies and their options
Healing often requires more than information. It requires perspective, experience, and guidance. Some obstacles are physical—degeneration, inflammation, infection. Others are deeper: genetic vulnerabilities, nervous system dysregulation, or loss of direction after years of illness.
Explore Health exists to help patients navigate that terrain with clarity, honesty, and hope—grounded in real clinical experience, not trends or shortcuts.

Dr. Sean earned his Doctorate in Physical Therapy in 2001 and opened up his first clinic in 2004. Dr. Sean earned his bachelor’s degree in Exercise Science from Arizona State University and graduated ASU with a 4.0 GPA, and was Awarded “Outstanding Senior of the Year” in 1997.
