Dr. Karl R.O.S. Johnson, DC
DC, CFMC, FIFHI
Chiropractic Physician · Certified Functional Medicine Clinician
A Different Kind of Practitioner
Dr. Karl R.O.S. Johnson has spent decades helping people overcome chronic health challenges that conventional medicine couldn't solve. His approach is rooted in a simple but powerful belief: the body is always willing to heal — when you give it the right information.
Now, through Functional Gene Wellness, Dr. Johnson brings that same philosophy to a new frontier: your genetic blueprint. By combining advanced genetic testing with functional medicine principles, he helps health-conscious individuals understand exactly what their DNA is telling them — and how to use that knowledge to optimize nutrition, energy, and long-term vitality. All delivered virtually, wherever you are.
Why I believe in this
I Did It Myself First
Dr. Johnson's commitment to genetic wellness isn't just professional — it's deeply personal. Motivated by his own family health history, he underwent comprehensive genetic testing on himself. What he discovered changed everything.
His results revealed hereditary hemochromatosis (a condition causing the body to absorb too much iron), genetic gluten intolerance, severely compromised detoxification pathways, and vitamin D receptor polymorphisms — all conditions that can silently undermine health for years without a conventional diagnosis.
These discoveries allowed Dr. Johnson to make targeted, proactive changes to his nutrition, lifestyle, and supplementation — before symptoms became serious. That experience is the foundation of everything he does at Functional Gene Wellness. He knows firsthand what it means to have your genes decoded, and what it means to act on that knowledge.
"I didn't wait for symptoms to appear. My genes told me what was coming — and I changed course. That's exactly what I want to help you do."

The philosophy
Treat the Individual, Not the Diagnosis
Whole-Person Perspective
Conventional medicine often treats the body in segments. Dr. Johnson's approach considers every interconnected system — genetic, neurological, hormonal, metabolic, and digestive — as part of a single, unified whole.
Root Cause Over Symptom Management
Rather than masking symptoms, Dr. Johnson uses advanced diagnostic tools — including genetic testing — to uncover the underlying imbalances driving your health challenges.
Personalized, Evidence-Based Care
Every recommendation is grounded in scientific evidence and tailored specifically to you. No generic protocols. No one-size-fits-all plans. Your genes, your history, your goals.
Empowerment Through Education
Dr. Johnson believes you are an integral part of your own healing journey. He takes the time to explain the 'why' behind every recommendation, so you leave each session with deeper knowledge of your own body.
The origin story
Healing Runs in the Family
Dr. Johnson's passion for natural healing was shaped long before he entered practice. His grandfather, a revered healer from Sweden, served as a Detroit Tigers baseball trainer in the 1930s and 40s and founded the Bloom Health Institute in Detroit — a legacy of helping people heal without drugs or surgery.
That legacy ignited Dr. Johnson's own calling. He graduated Summa Cum Laude from Palmer College of Chiropractic and spent the next four decades deepening his expertise across neurology, functional medicine, genetics, and metabolic health — always asking the question his patients needed answered: 'What is the root cause?'
The discovery of genetic testing as a clinical tool was a turning point. It provided the missing piece — a way to understand why two patients with identical symptoms could respond so differently to the same protocol. Your genes hold the answer. Dr. Johnson's role is to help you read them.
