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.

After earning a Doctorate in Physical Therapy from Arizona School of Health Sciences,  he helped grow and expand various clinics in the Phoenix Area and entered into private practice in Casa Grande, AZ in 2004.  He is experienced in working with a vast spectrum of patients, ranging from professional athletes to children and older adults.  He has a passion around seeing his patients, peers, and families win, and has focused extensively on manual physical therapy since 2001 because he found that although traditional physical therapy was helpful, it didn’t go the extra mile to help patients achieve their maximum potential with recovery.  Dr. Sean believes every client encounter is a unique opportunity to learn from his patients and become better at serving others.

Dr. Flannagan is married to Lina Flannagan, the business manager of OneAccord, and together have two amazing young boys who, on special occasions, accompany their dad and help create a cheerful environment at the clinic.  They also have two boxers, Argus and Toby, whom love to play with the family and are great with the kids!

Describe the essence of what you do in your role at One Accord Physical Therapy?

I have multiple roles I play within our organization.   In regards to patient care, I like to think I am a facilitator of healing for patients.  My desire is to see them win and achieve the best possible outcome, so when treating patients I like to think I offer them hope, and a pathway to recovery.

In regards to the company as a whole, I have the opportunity to create a work environment that fosters growth, compassion and fun!  I love being an employer, and I enjoy developing, training and growing people.

What are some of your personal interests, outside of work?

I love my family.  I married “up” and I know my wife makes me better every day.  I have two amazing kids that I enjoy playing sports, video games and just hanging with.  We also have two boxers as part of the family.  For fun I enjoy golf, the outdoors, snowboarding, reading and just learning. My wife and I also have a relationship & communication training company, Solid Life International, that serves married couples, business owners and executives.

What are some things you believe in? What is your favorite quotes or words of wisdom?

I believe, that with God, all things are possible. Without Him I would be lost. We have a family first environment, I put my family first, I expect my employees to do the same.

QUOTES:

“Build people, and they will build your company.”  Dr. Tom Anderson

“It’s all good.”       “And if you did know. . . “

“How is that working for you?”       “What does that look like to you?”

“120 years divided by eternity is Zero . . . you have zero time here, what have you done with your zero-time? Your life is but a vapor, play big.”

Draw near to God, and He will draw near to you. James 4:8

“I want to do something so big, it will fail without you Lord….” John Waller

What do you like most about working for One Accord PT?

I love our employees.  I am honored by the team we’ve attracted, trained and developed.  They come every day and give their all for our patients.  I am humbled by them every day.  I love that I get to go to work and have fun with a great team of individuals!

What do you like most about caring for patients?

That we are a source of hope, relief and results.  Since we take a hands-on, manual therapy approach that is unlike 95% of traditional physical therapy practices, we get results, so our patients actually get better.  Each patient is unique, and we get to experience that uniqueness every visit.  I learn just as much from them, as they do from me, sometimes more.

Why did you choose to become a physical therapist?

I was always fascinated by the body and loved sports.  This gave me a career that combined both the human body and movement!  Now, I’ve learned that physical therapy is the avenue through which I get to release my gift of laughter, fun and encouragement with a lot of people every day.

What do you think patients like MOST about you?

I get a lot of comments about my laugh.  Yes, I love to laugh, I believe laughter is medicine, and I’ve found it doesn’t come with negative side effects outside sore cheeks and abdominals at times.

What do you think patients like MOST about OneAccord Physical Therapy?

That we are truly here to serve and that we really work as a team.  I’m humbled by the number of other business owners and patients who pull me aside to comment on our staff and how well they enjoy each of them and the healing environment we create as a team.
