"My experience with Dr Fennel has been the missing piece. I’ve been working through trauma with counseling and coaching, but hit a wall called ‘let it go’. I’d love to do that… but how? The answer for me has been NET therapy, diet, carefully selected supplements and judicious lab testing. Working with Dr Fennel has been a very positive experience and I can’t recommend him enough. I feel more like ‘me’ with each appointment. I’m seeing my therapist less and my energy levels are continuing to climb."

Address the Root-Cause for Complex, Chronic Symptoms

MOLD ILLNESS

One of the most misdiagnosed conditions worldwide. Symptoms are real and the path forward is individualized.
TRAUMATIC BRAIN INJURY AND NERVOUS SYSTEM DYSFUNCTION

Brain fog, neurological autoimmunity, and unaddressed TBI… understanding these is the key to real recovery.
GUT HEALTH

Most health issues involve the gut… but not all start there. Personalized protocols beat universal cleanses every time.
AUTIMMUNE CONDITIONS

Under the right conditions, your immune system can turn against your own body. Hashimoto's, rheumatoid arthritis, multiple sclerosis, lupus… these conditions all have a root cause. Remission is possible. Let's find it.

New Patients: Begin Here

Dr. Cole Fennel's path into functional medicine is deeply personal. His wellness journey began with an immersion into nutrition and lifestyle changes in an attempt to improve his athletic performance as a rock climber. That interest turned into a passion, leading him to complete his undergraduate degree and set his sights on becoming a chiropractor.

Early in his education, something shifted—his own health took a turn. Riddled with intense fatigue, brain fog, and dizziness, he received a Lyme disease diagnosis and, years later, uncovered a likely lifelong struggle with mold toxicity. Rather than pursuing conventional treatment, he took a holistic approach, turning to functional medicine and applied kinesiology. The improvements he experienced only deepened his belief in natural healing and inspired him to keep learning so he could help others do the same.

"I wanted to share what I was learning more deeply with others."

Today, Dr. Cole helps patients uncover the root causes behind chronic, complex symptoms through highly personalized care that supports the body chemically, physically, and emotionally. He specializes in mold illness, Lyme disease and Lyme co-infections, autoimmunity, chronic fatigue, traumatic brain injuries, infertility, and performance optimization.

Dr. Cole is currently the only functional medicine practitioner in Arkansas certified by the Kharrazian Institute and the only chiropractor in the state certified in Neuro Emotional Technique (NET).
